The Surface on a Neuron That Discharges the Contents of Synaptic

Question

The surface on a neuron that discharges the contents of synaptic vesicles is the
A)dendrite.
B)axon hillock.
C)node of Ranvier.
D)postsynaptic membrane.
E)presynaptic membrane.

Accepted Answer

The presynaptic membrane is the surface on a neuron that discharges the contents of synaptic vesicles into the synaptic cleft, allowing for communication with the postsynaptic neuron. This process is known as neurotransmitter release. The dendrite receives signals from other neurons, the axon hillock is the start of the axon and acts as an integrating center for incoming signals, and the node of Ranvier is a gap in the myelin sheath of an axon where action potentials are generated. The postsynaptic membrane is the specialized region of the membrane of a postsynaptic neuron that is in close proximity to the presynaptic terminal and receives the neurotransmitter signal.
