Muscular System Anatomy And Physiology Modernheal The trunk muscles include (1) those that move the vertebral column; (2) anterior thorax muscles, which move the ribs, head, and arms; and (3) muscles of the abdominal wall, which help to move the vertebral column and, most important, form the muscular “natural girdle” of the abdominal body wall. anterior muscles. The musculoskeletal system. the muscular system is made up of muscle tissue and is responsible for functions such as maintenance of posture, locomotion and control of various circulatory systems. this includes the beating of the heart and the movement of food through the digestive system. the muscular system is closely associated with the.
Muscles Diagrams Diagram Of Muscles And Anatomy Charts The muscular system is composed of specialized cells called muscle fibers, which contain contractile proteins that enable them to contract and relax. the main types of muscle tissue are: skeletal, cardiac and smooth muscles. skeletal muscles are voluntary muscles attached to bones, which enable movement of the skeleton, and maintain body. 1. nerve releases a neurotransmitter (acetylcholine) 2. neurotransmitter causes the muscle cell membrane gates to open. 3. ions (na and k ) exchange places causing the sarcoplasmic reticulum to release ca 2 . 4. this release of ca starts the muscle contraction as the actin filaments slide past the myosin filaments. Definition. the muscular system is a set of tissues in the body with the ability to change shape. muscle cells connect together and eventually to elements of the skeletal system. when the muscle cells contract, force is created as the muscles pull against the skeleton. The primary job of muscles is to move the bones of the skeleton, but muscles also enable the heart to beat and constitute the walls of other vital hollow organs. there are three types of muscle.

Click to view larger image. the muscular system is responsible for the movement of the human body. attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.
