Transcript of The Muscular System

What is the Muscular system?
The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body.
The Muscles
a band or bundle of fibrous tissue in a human or animal body that has the ability to contract, producing movement in or maintaining the position of parts of the body.
Skeletal Muscle
a muscle that is connected to the skeleton to form part of the mechanical system that moves the limbs and other parts of the body.
Visceral Muscle
the visceral muscle tissue (which lines the blood vessels, stomach, digestive tract, and other internal organs) are composed of bundles of specialized cells capable of contraction and relaxation to create movement.

The Muscular System
Cardiac Muscle
Cardiac muscle is an involuntary, striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle
Smooth Muscles
Smooth muscles are controlled directly by the autonomic nervous system and are involuntary, meaning that they are incapable of being moved by conscious thought. Functions such as heart beat and lungs (which are capable of being willingly controlled, be it to a limited extent) are involuntary muscles but are not smooth muscles.
Aerobic and anaerobic muscle activity
In aerobic respiration, glucose and oxygen are converted into energy, carbon dioxide and water. ... In anaerobic respiration, glucose is converted into energy and lactic acid.
What the muscles need to work
The muscles in the muscle system need oxygen an nutrients to funtion properly
