The Muscular System

The muscular system is an organ system that permits movement of the body, maintains posture, and circulates blood throughout the body. The muscular system consists of:

The skeletal muscle are consciously controlled muscles that contract the muscles and cause movement of those bones. Examples of activities that involve skeletal muscles are running, chewing, writing, and typing. Smooth muscles are also known as VISCERAL muscle. The smooth muscle is the weakest muscle, but it plays an essential role. The essential role that it plays is contracting the muscles to allow food to move along the digestive tract. The cardiac muscles is an involuntary striated muscle that constitutes the main tissue of the walls of the heart. The function of the cardiac muscle tissue is to keep your heart pumping through involuntary movements. The bone matrix acts as a reservoir for a number of minerals important to the functioning of the body. These minerals that are stored within the bone tissue are still able to release it back into the bloodstream to maintain levels needed to support physiological processes. Bones also serve as a site for fat storage and blood cell production. The softer connective tissue that fills the interior of most bones are referred to as bone marrow. There are two kinds of bone marrow, yellow marrow and red marrow. Red blood cells, white blood cells, and platelets are all produced in the red marrow.
