Question

______________ detect environmental signals and convey this information to the central nervous system, _____________ convey signals from one neuron to another, and ___________ convey signals from the central nervous system to effector organs.

• A. Afferent neurons; efferent neurons; interneurons
• B. Efferent neurons; interneurons; afferent neurons
• C. Interneurons; sensory neurons; efferent neurons
• D. Afferent neurons; interneurons; efferent neurons

Answer 1

The correct option is D Afferent neurons; interneurons; efferent neurons

Sensory neurons: These neurons are also called afferent neurons. Their function is to receive initial stimuli from sense organs.

Interneurons: These types of neurons are also called connector neurons or association neurons. They “read” impulses received from sensory neurons. Interneurons are found in the spinal cord or brain.

Motor neurons: These neurons are also called efferent neurons, and their function is to stimulate effector cells.
