Question

the cluster of fibers at one end of a neuron that receive messages from other neurons are referred to as
o dendrites.
o axons.
o the myelin sheath.
o terminal buttons.

Explanation:

To solve this, we analyze the function of each neuron part:

• Dendrites: These are the branch - like structures at one end of a neuron that receive signals (messages) from other neurons.
• Axons: Axons are responsible for transmitting signals away from the neuron's cell body, not receiving them.
• Myelin sheath: It is a fatty layer that insulates axons to speed up signal transmission, and it has nothing to do with receiving messages.
• Terminal buttons: These are at the end of axons and are involved in sending signals to other neurons (e.g., by releasing neurotransmitters), not receiving.

So the correct option is the one related to dendrites.

Answer:

A. dendrites.
