Axons

Question

Axons
A) contain the nucleus.
B) are numerous extensions from each neuron.
C) do not have a trigger zone.
D) have a distal portion that branches to form the presynaptic terminals.
E) do not have a resting membrane potential.

Accepted Answer

Axons have a distal portion that branches to form the presynaptic terminals, which communicate with other neurons or effector cells, such as muscle or gland cells. The nucleus is located in the cell body of the neuron, not in the axon. Axons are usually a single extension from each neuron. Axons have a trigger zone where the action potential is generated. Like all cells, axons have a resting membrane potential, which is the difference in electrical charge between the inside and outside of the cell.
