Livestrong - Five Functions Of The Muscular System

New York - United States

The muscular system in your body is composed of skeletal muscle, cardiac muscle and smooth muscle. Skeletal muscle attaches primarily to your skeleton and moves voluntarily or by reflex. Cardiac muscle is the muscle of your heart and contracts involuntarily. Finally, smooth muscle is found in your blood vessels, eyes, hair follicles and the walls of hollow organs like your stomach and intestines.

The primary function of skeletal muscle is to produce voluntary gross and fine movements to keep you alive. Large movements include walking, standing, gathering food, cooking food, turning in a chair, running, playing sports and lifting weights. Fine motor skills or smaller movements include chewing, closing your eyes, blinking, typing, writing and talking. Your skeletal muscles will also contract as a reflex to stimuli, like moving your hand from a very hot coffee cup or blinking your eyes when an eyelash lands on the surface of the eye.

The muscular system is a system of tissues - called muscles - throughout the body which allow you to move. Most of the muscles in the body are under conscious control and are moved by commands sent to the muscles from the brain via the nervous system. However, some muscles (such as the cardiac muscles) are involuntary - that is, they move regularly without any conscious control. Except for the involuntary muscles, muscle fibers are connected to t

Muscles are responsible for your body's every move. Muscles keep your gut from sagging and your lungs pounding. Muscles are more than movers. Muscles make the heat that keep you warm. If you leap, bend, or reach, this is a result of a muscle action. A muscle makes itself smaller when it contracts and larger when it relaxes. Types of Muscles: Skeletal Smooth Cardiac

Medpedia:Muscular System
United States

The muscular system consists of the more than 600 muscles of the body and their associated fascia, tendons, tendon sheaths, and bursae. Muscles largely consist of skeletal muscle fibers, and are innervated by motor nerve fibers of peripheral nerves. Conscious and subconscious contractions of muscles affect body posture, and generate reflex, spontaneous (or automatic), and voluntary movements.

Skeletal muscle tissue is attached to bones by tendons, and is typically named according to its location. Skeletal muscle is voluntary muscle; that is, it can be made to contract by conscious effort. Cardia muscle tissue forms the walls of the heart and is involuntary by nature. The third type of muscle, visceral muscle is found in the walls of internal organs like the stomach and intestines and in blood vessels. The contraction of visceral

Musscles are very important part of our body. Without muscles the body will lose its ability to move and carry out various actions. In fact, without the human muscular system, we probably won't be able to survive. This is because most of the organs in the digestive system are made up of muscles and even our heart that keeps pumping blood is a muscle. If the muscular system is affected by any disease or disorder, it leads to many minor and in some
