Question

the cluster of fibers at one end of a neuron that receive messages from other neurons are referred to as

terminal buttons.

dendrites.

axons.

the myelin sheath.

Explanation:

To solve this, we analyze each option:

• Terminal buttons (or synaptic knobs) are at the end of axons and send messages, not receive.
• Dendrites are the branch - like structures at one end of a neuron that receive signals from other neurons.
• Axons are the long fibers that transmit messages away from the neuron's cell body.
• The myelin sheath is a fatty layer that insulates axons to speed up signal transmission, not for receiving messages.

Answer:

B. Dendrites (assuming the second option is labeled B, as the text shows "dendrites" as the second option; if the original labeling was different, adjust the identifier but the correct option text is "dendrites")
