B) Motor neurons and muscle neurons
C) Sensory neurons and interneurons
D) Sensory neurons and reflex neurons

Question

Quizplus · Accepted Answer

Sensory neurons and interneurons represent two distinct functional classes of neurons in the human nervous system. Sensory neurons receive input from sensory organs and transmit this information to the central nervous system. Interneurons, also known as association neurons, are located entirely within the central nervous system and are responsible for processing and integrating information from sensory neurons and communicating with motor neurons. Motor neurons, on the other hand, are responsible for transmitting signals from the central nervous system to muscles or glands, resulting in movement or secretion. Therefore, option C is the correct answer. Option A and B are incorrect as "uptake neurons" and "muscle neurons" are not actual types of neurons. Option D is incorrect as "reflex neurons" are not a distinct functional class of neurons, but rather a descriptive term for neurons involved in reflex arcs.
