Answer
Axon terminals release vesicles containing neurotransmitters.
Solution
The part of the neuron that releases vesicles containing neurotransmitters is the axon terminals.
Here’s a brief explanation of each option:
-
Axon terminals: These are the endpoints of the axon where neurotransmitters are stored in vesicles and released into the synaptic cleft to communicate with other neurons.
-
Dendrites: These are the branching extensions of a neuron that receive signals from other neurons but do not release neurotransmitters.
-
Myelin sheath: This is a fatty layer that insulates the axon and helps speed up the transmission of electrical signals, but it does not release neurotransmitters.
-
Cell body: This part contains the nucleus and organelles of the neuron, but it is not involved in the release of neurotransmitters.
Thus, the correct answer is axon terminals.

The axon terminals are the superstar part of the neuron when it comes to releasing those all-important neurotransmitters. These tiny swellings at the end of axons house vesicles filled with neurotransmitters, which are then released into the synaptic cleft to communicate with neighboring neurons. It’s like sending a tiny message from one neuron to another!
Dendrites, on the other hand, do a different but equally vital job. They act like antennas, receiving signals from other neurons. Once they pick up these chemical messages, they relay the information back to the cell body. So, while axon terminals send out signals, dendrites are busy picking them up—teamwork at its best!
