What tissue surrounds each individual muscle fiber? Name two characteristics of skeletal muscles. Differentiate between mucous, serous, cutaneous and synovial membranes. What is the primary function of skeletal muscle? Name the neurotransmitter responsible for initiating muscle contraction. What is the name of the process that occurs when the muscle fibers are contracting (shortening). What are the components of a motor unit? Which type of contraction is described as a prolonged and continuous muscle contraction, muscle twitch or tetanic contraction? Which type of contraction is occurring when someone pushes against a stationary wall? Isometric or Isotonic? During mild exercise, what process provides the richest supply of ATP for muscle contraction? What is described as a state of sustained partial muscular contraction that is vital for the health of muscles?
