______________ 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.
Afferent neurons; interneurons; efferent neurons
Sensory neurons: These neurons are also called afferent neurons. (Think of them as being affected by a sight, sound, smell, touch, or taste.) 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.
