Each Skeletal Muscle Fiber is Controlled by a Single ________

Question

Each skeletal muscle fiber is controlled by a single ________.
A) synaptic cleft
B) motor end plate
C) triad of transverse tubule and terminal cisternae
D) motor neuron whose cell body is located inside the central nervous system
E) neurotransmitter

Accepted Answer

Each skeletal muscle fiber is controlled by a motor neuron whose cell body is located inside the central nervous system. The motor neuron sends an action potential down its axon, which then releases neurotransmitters at the neuromuscular junction, ultimately leading to muscle contraction. The other options are not responsible for the control of each skeletal muscle fiber.
