The Cell
Cytology: study of the cell
Why study cells?
- Cells concentrate needed molecules, expel waste, synthesize larger molecules with complex functions, generate/store/use energy for metabolic processes, move (transport)
- Diseases begin at the cellular level (ex: cells dividing uncontrollably.. cancer)
- You are made of 75 trillion cells
Cells divided into:
- Sex cells: sperms/eggs
- Somatic cells: cells of the body
Looking at the structure of a cell can show the cell’s function
Environment of the cell
- Cytoplasm (intracellular fluid)
- Cytoplasm (intracellular fluid
- Extracellular fluid: usually fluid like, consists of resources

Anatomy of an Epic

...N D Dr. W. Yarborough English 205 July 22, 2012 The Anatomy of an Epic When it comes to the art of storytelling, one has to think of the great storyteller known as Homer. There are other great story tellers and epics that stand out in history such as Vergil and his epic The Aeneid. Though there is no duplicate to the epic poems of Homer. Homer of Greece was a blind bard known for a sensational memory and his ability to entertain an audience with the portrayal of his words. Two well known epic poems he told were The Odyssey and The Iliad. Both of these poems are very different from any story or poem written in ancient Greece. The structure, development, and the art of how each epic was told is the reason why each work is different and why each is called an epic. Especially the Odyssey it is the pentacle of an epic poem and contains everything needed to be considered so. The Odyssey is the great story of Odysseus and the sequel to Homer’s other epic the Iliad. The main character Odysseus is put through a lengthy journey on his return home to Ithaca from the battlefield of Troy. Over the span of 24 detailed books Homer tells Odysseus’ path and what he must face to get home. From the raging seas created by Poseidon, Odysseus’ lengthy stay with calypso, and his travels through the underworld. These and other conflicts that Odysseus faces are part of the elements to which make the odyssey and epic poem. In the first book of the Odyssey, Homer introduces a very......

Anatomy I

...Sarahbeth Cook May 12, 2011 Anatomy I Professor Kriota Willberg It is rare to find someone with a complete and perfect symmetrical body. Every human being has his or her own skeletal structure and no one is alike. If you are one of those few people lucky enough to have “perfect symmetry and balance,” you might end up finding a flaw elsewhere, or so I’d like to think. For myself, being as active of a dancer that I am, I already put a tremendous amount of wear and tare on my body, especially since I’ve been studying for eighteen years. The chances of me being perfectly in balance are slim to none. No matter how much physical therapy I do on my body, if I continue to dance with extreme physical motion I will always have something that is not in place. After doing these assessments I discovered a few things I didn’t realize about my body, but after analyzing them I see how they possibly may trigger some of my areas of discomfort. These imbalances affect my everyday activities, physical comfort, range of motion, and general sense of well-being. I have the privilege of having a physical trainer to assist me at work before every performance. She’s there to make sure my imbalances are cared for and I’ve been given exercises to strengthen my weak areas. The main areas I’ve decided that need major work consist on my shoulders, spine, core, and ankle/foot. I’ve selected a series of exercises that I believe will help improve my weaknesses. My overall posture is very good and......

Anatomy and Physiology

...Throughout this assignment the anatomy and physiology of the central nervous will be examined in relation to the affects a stroke may cause. The causes and symptoms will also be identified along with the various affects a stroke may have on an individual such as physical, emotional, and social impact. Finally, the care and treatments provided will be highlighted and will be referenced throughout according to relevant literature and guidelines such as Infection control, Health and Safety, and various government policies. According to the National Stroke Strategy 2007, a stroke is a condition in which the brain cells suddenly die due to a lack of oxygen. A stroke is often caused by an obstruction in the blood flow, or the rupture of an artery that feeds the brain (reference). The two main types of stroke which will be referred to throughout the text are hemorrhagic and Ischemic. National Stroke Strategy (2007) states that ‘an Ischemic stroke accounts for around 87% of all strokes and occurs when a blood clot (thrombus) forms that blocks the blood flow to a certain part of the brain’. When a blood clot forms somewhere in the body and breaks off to become free-floating, it is called an embolus (reference). This wandering clot may then be carried through the bloodstream and to the brain where it can then cause an ischemic stroke. A hemorrhagic stroke occurs when a blood vessel on the brain's surface ruptures and then fills the space between the brain and skull with blood or when...

...Environmental Health Perspectives Vol. 44, pp. 1-8, 1982 The Eye and Visual Nervous System: Anatomy, Physiology and Toxicology by Connie S. McCaa* The eyes are at risk to environmental injury by direct exposure to airborne pollutants, to splash injury from chemicals and to exposure via the circulatory system to numerous drugs and bloodborne toxins. In addition, drugs or toxins can destroy vision by damaging the visual nervous system. This review describes the anatomy and physiology of the eye and visual nervous system and includes a discussion of some of the more common toxins affecting vision in man. Anatomy of the Eyeball The eye consists of a retinal-lined fibrovascular sphere which contains the aqueous humor, the lens and the vitreous body as illustrated in Figure 1. The retina is the essential component of the eye and serves the primary purpose of photoreception. All other structures of the eye are subsidiary and act to focus images on the retina, to regulate the amount of light entering the eye or to provide nutrition, protection or motion. The retina may be considered as an outlying island of the central nervous system, to which it is connected by a tract of nerve fibers, the optic nerve. As in the case of the brain and the spinal cord, the retina is within two coats of tissue which contribute protection and nourishment. On the outside of the sphere, corresponding to the dura mater, a layer composed of dense fibrous tissue serves as a protective envelope, the......

Anatomy

...Anatomy is the branch of biology concerned with the study of the structure of animals and their parts; it is also referred to as zootomy to separate it from human anatomy. In some of its facets, anatomy is related to embryology and comparative anatomy, which itself is closely related to evolutionary biology and phylogeny.[1] Human anatomy is one of the basic essential sciences of medicine. The discipline of anatomy is divided into macroscopic and microscopic anatomy. Macroscopic anatomy, or gross anatomy, is the examination of an animal’s body parts using unaided eyesight. Gross anatomy also includes the branch of superficial anatomy. Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures, known as histology and also in the study of cells. The history of anatomy is characterized by a progressive understanding of the functions of the organs and structures of the human body. Methods have also improved dramatically, advancing from the examination of animals by dissection of carcases and cadavers (corpses) to 20th century medical imaging techniques including X-ray, ultrasound, and magnetic resonance imaging.

The Anatomy of Chimpanzees

...The Anatomy of Chimpanzees The male common chimp stands up to 1.7 m (5.6 ft) high and weighs as much as 70 kg (150 lb); the female is somewhat smaller. The common chimp’s long arms, when extended, span one and a half times the body’s height. A chimpanzee's arms are longer than its legs.[9]The bonobo is slightly shorter and thinner than the common chimpanzee but has longer limbs. In trees, both species climb with their long, powerful arms; on the ground, chimpanzees usually knuckle-walk, or walk on all fours, clenching their fists and supporting themselves on the knuckles thereof. Chimpanzee feet are better suited for walking than are those of the orangutan because the chimp has broader soles and shorter toes. Both the common chimpanzee and bonobo can walk upright on two legs when carrying objects with their hands and arms. The bonobo has proportionately longer upper limbs and more often walks upright than does the common chimpanzee. The coat is dark; the face, fingers, palms of the hands, and soles of the feet, hairless; the chimp, tailless. The exposed skin of the face, hands and feet varies from pink to very dark in both species but is generally lighter in younger individuals, darkening as maturity is reached. A University of Chicago Medical Centre study has found significant genetic differences between chimpanzee populations.[10] A bony shelf over the eyes gives the forehead a receding appearance, and the nose is flat. Although the jaws protrude, the lips are thrust out......

Anatomy of Merger

...Anatomy of a merger: behavior of organizational factors and processes throughout the pre- duringpost-stages (part 1) Steven H. Appelbaum Concordia University, Montreal, Quebec, Canada Joy Gandell Concordia University, Montreal, Quebec, Canada Harry Yortis Hydro-Quebec, Montreal, Quebec, Canada Shay Proper Montreal Stock Exchange, Montreal, Quebec, Canada Francois Jobin Kruger, Inc., Trois-Rivie Âres, Quebec, Canada Keywords Mergers and acquisitions, Organizational behaviour, Process efficiency, Managers Introduction Since the late 1980s, the total number of mergers and acquisitions (M&As) has far surpassed the number that occurred throughout the 1960s. Whereas the M&As throughout the 1960s were mainly due to unions between conglomerates, the 1980s and 1990s has witnessed an increase in M&As between firms of different sizes and different industry types (Tetenbaum, 1999). The trend to engage in this type of vertical integration or diversification does not seem to show signs of diminishing in the near future. Yet, at best, the firm that initiates the merger usually only achieves normal economic profits while the value created rests almost solely with the firm that was approached (Barney, 1997). The primary purpose of merging and acquiring new firms is usually to improve overall performance (Lubatkin, 1983) by achieving synergy, or the more commonly described as the ``2 + 2 = 5'' effect (Cartwright and Cooper, 1993a; Hovers, 1971) between two business units that will......

...As far as we know, anatomy is the oldest medical science. Cave paintings of the early Stone Age, about 30,000 years ago,* show a simple knowledge of the anatomy of animals, and it is assumed that these cave dwellers applied some of their anatomical knowledge to their own bodies. The civilizations of the Babylonians, as Syrians, Egyptians, Chinese, and Hindus made no serious attempt to learn anatomy because they were interested in the supernatural world, not the natural one, and their cultures placed strong religious restrictions against debasing the body. Any anatomical dissections that were performed on animals were made to "study" organs in an effort to predict the future and to tell fortunes. *The Stone Age, the earliest known period of human culture, is characterized by the use of small stone tools. Anatomy in Ancient Greece The systematic study of anatomy may have begun in the fifth century B.C ., with the work of two Greek scientists, Alcmaeon (ca. 500 B.C.) in Italy andEmpedocles (ca. 490-430 B.C) in Sicily, where Greek culture and science flourished. Alcmaeon was probably the first person to dissect the human body for research purposes, and he is also given credit for proposing that the brain is the center of intelligence. Empedocles, who believed that the heart distributed life-giving heat to the body, initiated the idea that an ethereal substance called pneuma, which was both life and soul, flowed through the blood vessels. Although such early anatomists were......

In the very early years of life, playing and using their imagin gives children a chance to make connections. When playing store, it is common for children to ask their teacher what a specific food is or what a box says. In first grade children begin to learn from their mistakes. When they do things wrong one way they then learn what not to do next time, and what to try instead. In third grade children learn by working together. This allows students to pull from the information the other students know. The students help each other and this gives the children a chance to learn different problem solving methods. Testing students give teachers a great indicator of how much each student knows. This will give the teacher a good starter point or gives them a chance to prepare for what they may have to go over again. Finding students strong points and making the connections on how that subject was taught gives the teacher a great indicator of how they learn. There are many different ways to learn; Visual, Auditory, and Kinesthetic. Visual learners use images to help better understand what is bring taught. Somone telling you an apple is red or the sky is blue does not hold as much promise as knowing that an apple is red because you have seen it or the sky is blue because you stood outside......

...Lisa Wright Anatomy and Physiology I 09/08/2011 Journal Questions 1-6 Journal # 1 Why does our skin age when even at 90, the outer layer is only 3 weeks old? Over time, the skin looses its flexiblity/collagen. The collagen becomes less elastic and thinner. This is where the problems with getting more moisture to the upper layer, the epidermis, begins. When you are young like in your 20s, you have more fatty vessels in your skin, as you age the fat dissapears. Journal # 2 What is the function of the multiple nuclei in striated muscle cells? Some nuclei that is present in the Muscles are Mytoblast. They form individual muscle fibers. The mytoblast that do not fuse with muscle fibers remain in the adult muscles and become sattelite cells. After an injury, these suspected sattellit celss can get bigger and divide. They can fuse with damaged fibers from the muscle and then assist in the regeneration of the muscles tissues. Journal # 3 How is the concept of Homeostasis (or its loss) related to disease & aging? Homeostasis maintains the internal conditions of your body. For Example: when your body uses a ton of energy and gets hot, you body sweats in response to that. When you age, alot of energy is not used as often as you used it when you were young. This is how diseases such as arthritis can occur much easier. You immune system can slow down as well. When you age, your body gets out of balance and out of homeostasis. Then you become more......
