In the context of AP Psychology, which of the following best describes the primary function of sensory neurons in the nervous system?
A
They produce myelin to insulate axons and speed up neural transmission.
B
They connect neurons within the brain and spinal cord to facilitate communication.
C
They carry signals from the central nervous system to muscles and glands.
D
They transmit information from sensory receptors to the central nervous system.
Verified step by step guidance1
Step 1: Understand the role of different types of neurons in the nervous system. There are three main types: sensory neurons, motor neurons, and interneurons.
Step 2: Identify the function of sensory neurons. Sensory neurons are responsible for carrying information from sensory receptors (like those in the skin, eyes, ears) toward the central nervous system (CNS).
Step 3: Differentiate sensory neurons from motor neurons, which carry signals away from the CNS to muscles and glands, and from interneurons, which connect neurons within the CNS.
Step 4: Recognize that myelin production is a function of glial cells, not neurons themselves, so sensory neurons do not produce myelin.
Step 5: Conclude that the primary function of sensory neurons is to transmit sensory information from the body to the brain and spinal cord, enabling perception and response to stimuli.
