The muscular system is what is responsible for the way that we move. Without the muscular system‚ we wouldn’t be able to participate in the normal activities that we do today. There are 700 known/named muscles that are attached to the human skeleton. There are three different types of muscle that can be found in the human body. The Visceral muscle which can be found inside organs such as the stomach. This type of muscle is controlled by the unconcious part of the brain. This muscle is also known

Muscle Fiber contractions for our purposes begins with the arrival of action potential (action potential- is an electrical current) at the end of the axon terminal (axon terminal- the swollen distal end of the motor neuron axon). When the action potential reaches the axon terminal the action potential causes the voltage- gated calcium ion channels to open allowing calcium to flow in from extracellular fluid. The presence of calcium in the axon terminal causes synaptic vesicles (synaptic vesicles-

how muscles contract‚ this is shown by the 5 stages of the sliding filament theory. When the muscle contracts‚ the myosin filaments attach themselves to similar actin filaments‚ this attachment causes formation in chemical bonds this then forms the cross bridges. Myosin and actin molecules are made in a series‚ this series is what makes up a muscle cell. This basic module is called the sarcomere‚ these are what gives the tissue of a skeletal muscle its appearance. The mechanism within muscle contraction

Foster Collage of Physical Education & Sports Mr. April 13‚ 2015 What is the Neuromuscular System? According to research the neuromuscular system is to make the body move‚ a signal travels along neurons nerve cells from the brain to the spinal cord. There‚ "lower motor neurons" pass the message on to the muscles. The end of every lower motor neuron releases a chemical‚ which is

The Muscular System Teacher pages The muscular system allows us to move. Adults have a certain fixed number of muscle cells‚ approximately 602. . Through exercise‚ such as weight lifting‚ the cells enlarge but the number of cells does not increase. Structure and Function There are three types of muscle tissue—smooth‚ skeletal‚ and cardiac. Each has its own distinctive function‚ and therefore‚ its own distinctive structure‚ but all muscles allow movement of some kind. Skeletal Muscle

Skeletal System and Muscular System In anatomy and physiology we study the structure of living things and the function of living systems. In physiology‚ the scientific method is applied to determine how different organisms‚ organ systems‚ organs‚ cells‚ and biomolecules carry out the chemical or physical function that they have in the living system. Both anatomy and physiology are subcategories of biology. Throughout our class we have discussed many different systems of the body. One system that is

Muscle contractions and stimulations play a very integral part in the functioning of an organism and muscles are especially function for force production and motion all this is highly influenced by specific temperatures‚ electrical impulses‚ proteins and enzymes and other factors that occur whether on the inside or the external environment of an organism (Amitrano & Tortora‚ 2012). Proteins as defined by Cheeke 2010‚ are molecules that are made up of amino acids and are responsible for almost all

Skeletal‚ Muscular‚ and Integumentary System The Muscular System Our muscular system provides the main source of force to put our bodies into motion. More than 40% of our body mass is composed of muscle. Types of Muscular Tissue There are three types of muscle tissue: 1. Skeletal Voluntary movement‚ attached to bones. 2. Smooth Involuntary movement‚ found in digestive tract‚ circulatory system‚ etc. 3. Cardiac Involuntary movement‚ found only in heart. Muscle Contraction Skeletal Muscle
