Nerve fiber layer

Scientists have long thought that the cause on why our fingers prune was caused by osmosis. Osmosis is the swelling of the outer layer of the skin as water is soaked into cells (Perkins, 2013). Scientists thought osmosis was the answer, because after having your fingers in water for a long period of time, much of the sebum is rubbed off, and our outer layer of skin starts to absorb water, which is osmosis. While scientists had an impression that osmosis was the answer to why our fingers prune

Better understanding of glaucoma, requires assessment of the different components incorporate ,retinal nerve fiber layer (RNFL), and, and visual function. On the other hand, elevated intraocular pressure, are not only risk factor of glaucoma .RNFL thickness measured by optical coherence tomography (OCT) is a reliable early marker of glaucoma[1,2]. As the pathogenesis of glaucoma involves the degeneration of axons as well as cell bodies and dendrites, The primary site of axonal damage in glaucoma

rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous system. Understanding how the neurons work is vital to understanding the nervous system. Neurons The neuron has two important structures called the dendrite and axon, also called nerve fibers. The dendrites are like tentacles that sprout from

is formed by various interconnected networks, called plexuses, of enteric neurons, glial cells, and axons (Widmaier et al. 2014). The majority of these nerve cells are found within two different arrangements of ganglia (Fig. 1): the myenteric (Auerbach’s) plexus and the submucosal (Meissner’s) plexus (Furness 2006; Guyton and Hall 2006). The nerve cells’ axons either synapse with additional neurons in the plexus or innervate the smooth muscle of digestive organs (Furness 2006). Neural activity in

organ systems involved with performing or assisting with the action of typing. The integumentary system acts as a barrier to protect the fingers from harm or pathogenic agents from the keyboard. Thick skin, such as the skin of palms, has five skin layers including the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum, in order to protect the fingers from wear and tear. The integumentary system also provides protection with chemical barriers such as the acid

made of three separate layers of tissues. Starting from the inner layer out, they are the: tunica interna, tunica media, and tunica externa. The structure of the vessels differ slightly between the arteries and veins which will described shortly. The tunica interna is the innermost and thinnest layer of the blood vessel, which contains a few layers within it. However, the tunica interna does not greatly contribute to the thickness of the blood vessel. It is also the layer that is in direct contact

tissue Epithelial tissue Epithelial tissue & subtypes The epithelial tissue covers inner and outer layer/surface of the body, e.g. the stomach, or blood lines, vessels and the lung. The epithelium consists of closely packed, flattened cells that make up the inside/ outside lining of body areas. Epithelial tissues that cover/line surfaces are classified by cell shape and by the number of cell layers, the image on the left is the subtypes of epithelial tissue; Squamous - flattened cells, fried egg

absorbs the stomach and gut, filters the kidney, and forms glands traits. It closely attached to each other forming a protective barrier, has no blood vessels but can soak up nutrients from blood vessels in connective tissue underneath, can have lots of nerves in it, very good at regenerating for example fixing a sunburn or skinned knee. There are different types of epithelium by shape and cell. The shapes are squamous, cuboidal, and columnar. By cell there is simple and stratified epithelium. Connective

Marigold Kotey 12/03/15 Case Study #4: Wearing on Her Nerves Dr. Fundaro Part I 1. What components of the nervous system are involved in physical sensation? How does sensory impulse move throughout the body? The components of the nervous system that are involved in the physical sensation is the peripheral nervous system, which is divided into two groups they are, sensory and motor divisions. The sensory impulse moves through the body by stimulating a receptor in the skin, and it goes through the
