Muscular System

by Mallory Cutler

Functions

Involuntary, voluntary, and cardiac are the muscle systems main muscles. Voluntary muscles can be controlled by yourself, for example you can move your arms and legs by yourself. Cardiac muscles makes up walls to protect the heart. Involuntary muscles are muscles you can't control by yourself, they work automatically. Blinking can be involuntary because it's an action to protect your eyes from damage. A heartbeat can also be involuntary, but not all the time, you can't stop your heart from beating right away, if you hold your breath it will stop soon, but not right away. Muscles that help food get through the intestine are also involuntary. Smooth muscles can not be controlled. Tissues that are in the muscle system include cardiac muscle cell, skeletal muscle, smooth muscle, and visceral muscle.

Diseases In The Muscular System

Diseases in the muscular system include Cerebral Plasey, Dermatomyositis, Compartment Syndrome, and Muscular Dystrophy. Cerebral Plasey is common congenital disorder that affects the posture and balance. Dermatomyositis is inflammatory myopathy affecting skin and muscle, harming connective tissue. Compartment Syndrome is blood vessels, muscles, and nerves get compressed in a closed area, which ends up cutting off oxygen supply. Muscular Dystrophy is the cause of damage of muscle fiber and the effect is losing the ability to walk, and trouble breathing or swallowing. It usually happens in childhood and primarily in boys. There is no cure for muscular dystrophy, but medications and therapy can help control it and slow the course of the disease. Exercising and eating a balanced diet can help prevent all these diseases. You can not live without the muscular system because it contains ligaments, tendons and muscles that connect to bone.

Interacting With Other Organ Systems

The muscular system interact with many systems inculding skeletal, nervous, circulatory, and digestive. The circulatory system brings down nutrients to the muscles and takes away wastes. The digestive system helps chew up the food, and move food from the mouth to the stomach. The skeletal system protects the heart (which is a muscle) and provides structure for the muscles to be attached to.
