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

Humans breathe and speak daily without a thought of what really goes into this one aspect of communication. Even though breathing and speaking may seem like a mindless process‚ there are a number of muscles‚ ligaments and body parts that go into the mechanisms that make life what it is. In order to live and speak‚ we must be able to breathe. Respiration is the act of breathing. The act of drawing in a breath‚ or inspiration is the process of in-taking air. Air is taken in through the upper airways

is pumped by the heart and circulated through the body via a system of arteries and veins. It is an essential component of the body and without it we would not be able to survive. This paper discusses the anatomy and physiology of blood in a brief review. Anatomy and Physiology of Blood The blood is made up of four main components. These are plasma‚ red blood cells‚ white blood cells and platelets. The blood is circulated throughout the body by one of two types of vessels; arteries or veins

The musculo skeletal system is an organ system that gives humans the ability to move‚ it provides stability‚ protection‚ movement and support to the body . It is also made up of bones‚ tendons‚ ligaments‚ cartilage‚ joints and other connective tissue that binds tissues and organs together. The musculo skeletals job is to The skeletal system acts like a framework to support vital organs by keeping them place when doing vigourous sports‚ for example the vertebrae acts like a pillar and holds the

LABORATORY REPORT RENAL PHYSIOLOGY INTRODUCTION: The kidneys‚ which maintain the purity and constancy of our internal fluids‚ are perfect examples of homeostatic organs. They regulate the chemical content the pH and osmotic pressure of the blood. Kidneys filter gallons of fluid from the bloodstream. They then process this filtrate‚ allowing wastes and excess ions to leave the body in urine while returning needed substances to the blood in just the right proportions. Factors that affect urine

Even though cardiac muscle has an inherent ability to beat. the nodal system plays a critical role in heart physiology. What is that role? Ensures that depolarization proceeds in an orderly manner from atria to ventricles ; accelerates and coordinates heart activity to effectively pump blood. Electrocardiography 3.
