C) nodes of Ranvier
D) cell body

Question

Quizplus · Accepted Answer

Vesicles are directly associated with synaptic transmission. They contain neurotransmitters which are released into the synaptic cleft to bind to receptors on the postsynaptic membrane, generating a signal to the next neuron or effector cell. The axon carries the signal, the nodes of Ranvier are gaps in the myelin sheath that allow for faster transmission, and the cell body contains the nucleus and other organelles but is not directly involved in synaptic transmission.
