Nerve and neuron sound similar to most people‚ but they are two different components of the body (Martini‚ 375). Nerves are found only in the peripheral nervous system‚ while neurons are found in the brain‚ spinal cord‚ and peripheral nerve (Martini‚ 375). Neurons are nerves cells that are specialized for intercellular communication (Martini‚ 375). A neuron is composed of a cell body‚ dendrites and axon (Marieb‚ 376). A nerve is a bundle of axons or dendrites that is wrapped in connective tissues

muscle contraction Introduction For a skeletal muscle fiber to contract‚ a stimulus must be applied to it. The stimulus is delivered by a nerve cell‚ or neuron. A neuron has a threadlike process called and axon that my run 91 cm or more to a muscle. A bundle of such fibers from man different neurons composes a nerve. A neuron that stimulates muscle tissue is called a motor neuron. The motor neuron branches into terminal structures called telodendria that come into close approximation with

“Electromyography in the Abductor Pollicis Brevis‚ Bicep‚ and Tricep Muscles of a Human”. July 6‚ 2015. PCB 3713L- General Physiology Lab‚ Section #001 Introduction Skeletal muscles are responsible for most of the locomotion seen in humans and animals. Electromyography can be used to measure the electrical activity emitted from the muscle and nerves that control the muscle. This electrical activity is seen when a neuron ignites an action potential that activates the muscle fibers that were innervated

Schoffstall Introduction In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary

IMPULSE CONTROL DISORDERS Many of the self-control disorders involve disturbances in the ability to regulate an impulse - an urge to act. People with impulse control disorders act on certain impulses involving some potentially harmful behavior that they cannot resist. Impulsive behavior in and of itself is not necessarily harmful; in fact‚ we all act impulsively upon occasion. Usually our impulsive acts have no ill effects‚ but in some instances they may involve risk. Consider the following

Impulse control disorders are conditions in which the afflicted cannot control his or her actions. Examples of Impulse control disorders include Pyromania and Kleptomania‚ the uncontrollable urge to set fire to something and the urge to steal something usually invaluable for the sheer rush of stealing‚ respectively. Both these disorders sound like excuses to illegal activities but studies show that only 5% of shoplifters can be diagnosed with Kleptomania and less that 2% of people accused of arson
