Question

Quizplus · Accepted Answer

The synaptic knob, also known as the axon terminal, contains vesicles filled with neurotransmitters such as acetylcholine. These neurotransmitters are released into the synaptic cleft (the space between the synaptic knob and the motor end plate) to stimulate muscle contraction at the neuromuscular junction. Transverse tubules are involved in the transmission of the action potential into the muscle fiber, but do not contain vesicles filled with neurotransmitters.
