Action potentials travel the length of the axons of motor neurons to the axon terminals. These motor neurons extend from the brain or spinal cord to the sarcolemma of a skeletal muscle fiber extend from the brain to the sarcolemma of a skeletal muscle fiber extend from the spinal cord to the sarcolemma of a skeletal muscle fiber arise in the epimysium of a skeletal muscle and extend to individual skeletal muscle fibers My Answers Give Up Review Part Calcium entry into the axon terminal triggers which of the following events? Cation channels open and sodium ions enter the axon terminal while potassium ions exit the axon terminal. Acetylcholine is released into the cleft by active transporters in the plasma membrane of the axon terminal. Synaptic vesicles fuse to the plasma membrane of the axon terminal and release acetylcholine. Acetylcholine binds to its receptor. My Answers Give Up Review Part

Solution

PART C

These motor neurons extend from brain or spinal cord to the sarolemma of a skeletal musle fiber.

PART D

Calcium entry in the axon terminus triggers the event of Acetylcholine release into the left by active transporters in the plasma membrane of axon terminus.
