Matching
Match the following.
Premises:
Sarcomere lengthens as calcium is returned to sarcoplasmic reticulum, and the troponin-tropomyosin complex attaches to myosin binding sites on actin.
time between the stimulation of a muscle and the beginning of a muscle contraction
complete cycle of contraction and relaxation
decline in muscle activity as ATP levels decrease
increases muscle force by activating more motor units
contain gap junctions that permit rapid electrical stimulation of muscle cells
aerobically break down fatty acids and glucose
anaerobically break down creatine phosphate
Actin filaments slide over myosin filaments, and the sarcomere shortens.
Responses:
contraction
twitch
latent period
intercalated discs
fast-twitch fibers
relaxation
slow-twitch fibers
fatigue
recruitment
