Question

the small bulge at the end of the axon that sends messages to other neurons are called

axons.

dendrites.

the myelin sheath.

terminal buttons.

Explanation:

To solve this, we analyze each option:

• Axons are the long fibers that carry signals, not the bulges at the end.
• Dendrites receive signals, not send from axon ends.
• Myelin sheath insulates axons, not the bulges.
• Terminal buttons (or axon terminals) are the small bulges at the end of axons that release neurotransmitters to send messages to other neurons.

Answer:

D. terminal buttons.
