Question

the small bulge at the end of the axon that sends messages to other neurons are called axons. terminal buttons. the myelin sheath. dendrites.

Explanation:

To solve this, we analyze each option:

• Axons: Long fibers that transmit signals, not the bulge at the end.
• Terminal buttons: Small bulges at the end of axons that release neurotransmitters to send messages to other neurons.
• Myelin sheath: Insulates axons, not a bulge at the end.
• Dendrites: Receive signals, not send from axon ends.

Answer:

B. terminal buttons. (Note: Assuming the options are labeled as A. axons, B. terminal buttons, C. the myelin sheath, D. dendrites as per typical neuron structure questions)
