A) axon hillock.
B) varicosity.
C) axon.
D) dendrite.
E) nerve.

Answer 1

The axon is the part of the neuron responsible for transmitting electrical signals to other cells, ultimately leading to the release of neurotransmitters at the axon terminals.

Step-by-step explanation:

The structure on the neuron that transmits electrical signals to trigger the release of neurotransmitters is the axon. Neurons are specialized cells that transmit signals using electrochemical processes. An axon is a tube-like structure that extends from the cell body, conducting electrical signals to the axon terminals. The axon terminal contains synaptic vesicles that release neurotransmitters into the synapse, communicating signals to other neurons, muscle cells, or target organs. Some axons are insulated with myelin, produced by glial cells, which increases the speed of signal conduction and prevents signal loss. The insulation is punctuated by nodes of Ranvier, which help to recharge the signal as it travels down the axon.
