Muscle Contraction Diagram Quizlet Hip flexor, deep in pelvis; a composite of two muscles. sternocleidomastoid. one of two thick muscles running from the sternum and clavicle to the mastoid and occipital bone. semitendinosus. flexes leg at the knee and extends thigh at the hip; belongs to the hamstring group. muscular system learn with flashcards, games, and more — for free. Muscles attach to bones directly or through tendons or aponeuroses. skeletal muscles maintain posture, stabilize bones and joints, control internal movement, and generate heat. skeletal muscle fibers are long, multinucleated cells. the membrane of the cell is the sarcolemma; the cytoplasm of the cell is the sarcoplasm. Muscle contraction requires energy, and when atp is broken down, heat is produced. this heat is very noticeable during exercise, when sustained muscle movement causes body temperature to rise, and in cases of extreme cold, when shivering produces random skeletal muscle contractions to generate heat. Skeletal muscle is one of the three types of muscle tissue, alongside cardiac and smooth muscle. it is classified as a striated muscle tissue, which functions to contract and permit movements under voluntary control. this article will discuss the structure of skeletal muscle tissue, it’s mode of contraction and relevant clinical conditions.

When a skeletal muscle has been dormant for an extended period and then stimulated to contract, with all other things being equal, the initial contractions generate about one half the force of later contractions. the muscle tension increases in a graded manner that to some looks like a set of stairs. this tension increase is called treppe, a. Relaxing skeletal muscle fibers, and ultimately, the skeletal muscle, begins with the motor neuron, which stops releasing its chemical signal, ach, into the synapse at the nmj. the muscle fiber will repolarize, which closes the gates in the sr where ca was being released. atp driven pumps will move ca out of the sarcoplasm back into the.
