Which is True of Interneurons

Question

Which is true of interneurons?  
A) They detect stimuli.
B) They receive and send signals.
C) They control muscles.
D) They control glands.
E) They have a long axon.

Accepted Answer

Interneurons are responsible for receiving signals from sensory neurons and transmitting signals to motor neurons. Therefore, they are involved in communication between neurons within the nervous system. They do not detect stimuli directly, control muscles or glands, nor do they have a long axon, as they generally function within shorter distances within the nervous system.
