Transcript: 1.Migraine 2/3 of 300 million people suffering from migraines worldwide are women between the ages of 15 and 55 tippically due to hormonal influences 2. Myelin: Myelin begins to form around the axon around the 14th week of prenatal development. Not all axons are completely myelinated, but rather around the time the child starts walking and onward development continues. is an inherited defect in a lysosmal enzyme causes myelin to accumulate, burying neurons in fat. This defect is usually detected around six month old, gradually losing sight, hearing, and muscle function until death at age 4. However this disease is extremely rare. 3. Multiple Sclerosis (MS) blurred vision numb legs or arms 4.Neuroma 5. Impulse Conduction painful muscle cramps, convulsions, paralysis, and anesthesia can each result from channges in the permebility of axons to particular ions. A number of substances alter acon membranepermebility to ions. calcium ion are required to close sodium channels in axon membranes during an action potential. if calcium is dificient, then sodium ions diffuse through the membrain contiuallyso that impulses are transmitted repeadly. if the muscles continuously spasm due impulses traveled along axons (tetanes or tetany). Tetanic contraction may also occur when the diet lacks calcium and or vitamin D; prolonged diarrhea depletes the body of calcium. A small increase in the concentration of extracellular potassium ions causes the resting potential of nerve fibers to be less negative (partially depolariced). As a result, the threshold potential is reached with a less intense stimulus than usual. If the ectracellular potassium ion concentration is greatly decreased, the resting potentals of the nerve fibers may become so negative that action potentiials are not generated. In this case, impulses are not triggered, and muscles become paralyzed. Certain anesthetic drugs, such as procaine, the decrese membrane permeability to sodium ions. In tissuefluids surroundin an axon, these drugs prevent impulses from passing through the affected region. Consequently, the drugs keep impulses from reaching the brain, preventing perception of touch or pain. 6. Opiate Drugs: poppy plant 7.Drug Addiction: when a smoker increases the number of cigarettes smoked, the number of nicotinic receptors increases. so receptors are produced faster then they are taken apart. After a pirod of steady nictine exposure, many of the receptors malfunction and no longer admit the positive ions trigger the nerve impulse. this may be why as time goes oon it takes more nicotine to produce the same effect- a hallmark of addiction.

They constrict blood flow therefore can be dangerous to certain people. symptoms: tetanus MS is a disorder that affects 2.5 million people worldwide, and 400,000 in North America. About 70% of people notice the symptoms between ages twenty and forty; earliest three years, latest sixty-seven years. Caucasian Women are the most likely to get MS in regards to men and women of other races. Doctors consent History: Exposure: if a peripheral nerve is severed, it is important that the two cut ends be connected ASAP. However if the cut is larger than 3 millimeters, the regenerating axons may form a tangled mass called a neuroma. It is composed of sensory axons and is painfully sensitive to pressure. Neuromas sometimes complicate a patients recovery following limb amputation. Neurons do not divide.In the adult brain , the rare neural stem ccells are in a region called the centate gyrus and near fluid-filled cavities called ventricles. Neural stem were discovered in the 1980's, in songbirds. Today, human neural stem and progenitor cellre being used to screen drugs and are being delivered as implants to experimentally treat a variety of brain disorders. One day, a person's neural stem cells may be coaxed to help heal from within. enviromental triggers: pounding head waves of nausea extreme sensitivity to light and sound sometimes shimering images in the peripheral visual feild Anatomy Triptan is a vary

Transcript: Human Anatomy "Anatomy" as a word came from the greek words meaning "to cut up", as it was first studied through dissection. Da Vinci, Galen, Aristotle, and Vesalius were the first who scientists who really started anatomy. Da Vinci dissected human corpses and was known as "the father of anatomy as a science". Galen's research was directed towards knowing the function of parts of a body and how well adapted they were to their purpose. Vesalius wrote and in 1543 published his book "De Humani Corporis Fabrica" which means "On the Fabric of the Human Body". a couple important organs The human heart keeps blood flowing by pumping two ways. The right side pumps de-oxygenated blood to the lungs, and the left side pumps the newly oxygenated blood through the body The lungs are the site of gas exchange with the blood, putting oxygen in it to be carried to the rest of the body. The kidney regulates the concentrations of acids and extracellular fluid as well as keeping steady blood pressure. The liver synthesizes proteins and fatty acids, metabolises carbohydrates, and detoxifies the blood. The stomach stores and prepares food for digestion. It releases mucus to lubricate, acids to kill off bacteria, and anzymes to help break down the food. The spleen creates and stores red blood cells for when needed. The pancreas makes enzymes to help digest foods and hormones to keep blood sugar in check. Liver Stomach Heart Lungs Pancreas Kidney Spleen

Transcript: - All my definitions are found at annd my pictures were taken from The rest of my information is from the Human Anatomy Book. The skin disorders were found on fox2 The functions of the Integumentary System are: Maintain Body Temperature, Protection, Perception of Stimuli, Excretion, Synthesis of Vitamin D, Immunity, and Blood Reservoir. Dermis: the dense inner layer of skin beneath the epidermis, composed of connective tissue, blood and lymph vessels, sweat glands, hair follicles, and an elaborate sensory nerve network. Sebaceous glands: any of the cutaneous glands that secrete oily matter for lubricating hair and skin. Epidermis: the outer, nonvascular, nonsensitive layer of the skin, covering the true skin or corium Nerve: one or more bundles of fibers forming part of a system that conveys impulses of sensation, motion, etc., between the brain or spinal cord and other parts of the body. Asymmetry: the two sides of the pigmented spot or mole do not match. Border Irregularity: the borders of the lesion are not smooth but exhibit indentations. Color: the pigmented spot contains areas of different colors: blacks, browns, tans,and sometimes blues and reds. Diameter: the spot is larger than six millimeters in diameter, which would be the size of a pencil eraser. All About Me (: Hair Follicle:a small cavity in the epidermis and corium of the skin, from which a hair develops. 3. Seborrheic DermatitisSeborrheic dermatitis, which causes oily, waxy patches to develop on the scalp, is distinct from other forms of dermatitis. I have over 200 community service hours. I have applied to 6 colleges. The admission expectations for the colleges of my choice are both ACT and GPA. I'm looking forward too going in to Physical Therapy, and Cosmetology. I have started my FAFSA! Describing the layers of the skin location and function: Pacinian Corpuscles:a microscopic, onionlike body consisting of layers of connective tissue wrapped around a nerve ending, located in the deep layers of skin, tendons, etc., and functioning as a sensory receptor of pressure and vibration. Epidermis; The epidermis is the outer layer of skin. The thickness of the epidermis varies in different types of skin. The bottom layer, the stratum basale, has cells that are shaped like columns. In this layer the cells divide and push already formed cells into higher layers. As the cells move into the higher layers, they flatten and eventually die. The top layer of the epidermis, the stratum corneum, is made of dead, flat skin cells that shed about every 2 weeks. 1. Acne Acne is a skin disorder that causes pimples when the passageway that connects the skin’s pores to the oil glands becomes clogged. First degree burns only affect the outermost layer of skin, the epidermis. These cause slight swelling and redness and are fairly painful. Second degree burns affect the epidermis and the dermis. These burns are very painful and cause the skin to turn bright red and blister. Third degree burns affect the entire skin, including hair follicles, sweat glands, oil glands, blood vessels, and other structures. These burns aren't painful because even the pain receptors have been damaged, and are often leathery, white, brown, or tan in color. Human Anatomy 1st Degree Burn 5. Psoriasis Psoriasis is a chronic and disfiguring genetic disease. It is a buildup of excess skin tissue that looks red and thick and is covered with silvery scales. It first appears on the elbows and knees, but can spread to other parts of the limbs and even the trunk. Certain forms affect particular areas like the hands, scalp or the joints. Subcutaneour/hypodermis: situated or lying under the skin, as tissue. Define: 2. Eczema — Atopic dermatitis is the most common and is seen most often in children. One to three percent of adults compared to 10 to 20 percent of children have this long-term genetic disease, which causes itchy rashes in the crux of the elbows and behind the knees. Integumentary Project 3rd Degree Burn The functions of the Integumentary system are: Five types of Skin Disorders or Ailments: Adipose:fatty; consisting of, resembling, or relating to fat. Differences between 1st, 2nd and 3rd degree burns: 2nd Degree Burn What's the ABCD rule and what does it mean:? Work Cited page. Exocrine Glands: any of several glands, as the salivary glands, that secrete externally through a duct. 4. Skin CancerSkin cancer is the most common type of cancer in the United States. Melanin: any of a class of insoluble pigments, found in all forms of animal life, that account for the dark color of skin, hair, fur, scales, feathers, etc.
