Muscle Fiber Diagram Quizlet 10 the skin : understand the functions of the integumentary system. quizzes on the anatomy of the human muscular system, including the locations and actions of all the main muscles of the head and neck, the torso, and the upper and lower limbs. plus there are links to lots of other great anatomy quizzes; all 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. These tissues include the skeletal muscle fibers, blood vessels, nerve fibers, and connective tissue. each skeletal muscle has three layers of connective tissue (called “mysia”) that enclose it and provide structure to the muscle as a whole, and also compartmentalize the muscle fibers within the muscle (figure 10.3). The muscles all begin the actual process of contracting (shortening) when a protein called actin is pulled by a protein called myosin. this occurs in striated muscle (skeletal and cardiac) after specific binding sites on the actin have been exposed in response to the interaction between calcium ions (ca ) and proteins (troponin and tropomyosin) that “shield” the actin binding sites.

The energy source for muscle contractions is: calcium glucose atp cholinosterase. 7. the a band in a myofibril is an area of: thin filaments thick filaments transverse tubules motor end plates. 8. a sarcomere is defined as the section of fiber between: z lines a lines h zones i bands. 9. tendons connect: muscles to muscles muscles to neurons.
