In a skeletal muscle fiber, Ca2+ is released from a. ACh receptors. b. the motor end plate. c. the sarcoplasmic reticulum. d. the sarcolemma and T-tubules.
Stimulation of a muscle fiber by a motor neuron occurs ata. the neuromuscular junction.b. the transverse tubules.c. the myofibril.d. the sarcoplasmic reticulum.e. none of the above.
If a muscle cell had very short T-tubules, how much tension would the muscle fiber create, relative to a normal muscle fiber? Assume sarcoplasmic reticulum can still react to activity at the neuromuscular junction.
a)Less tension would be created.
b) No difference in tension creation.
c) More tension would be created.
d) No tension would be created.
