BIOLOGY Lecture Notes - Lecture 4: Skeletal Muscle, Neuromuscular Junction, Myocyte
Document Summary
Describe the molecular mechanism of skeletal muscle contraction in detail. The muscular system is an organ system consisting of skeletal, smooth and cardiac. It permits movement of the body, circulates blood throughout the body and maintains muscle. posture. It is composed of muscle fibers for contraction. Muscles are attached to bones, or internal organs and blood vessels and are responsible for movement. All the movements in the body are the result of muscle contraction. Skeletal or voluntary or striped muscles are those which are under conscious control. They are responsible for the movement of body parts and the locomotion. The main functions of these muscles are support, movement, protection, production of blood cells, storage of ions and endocrine regulation. Neuromuscular junction is the site where the motor nerve fiber and the skeletal muscle fiber meet. It is also known as synapse or synaptic cleft.
