First-Order Neurons ________

Question

First-order neurons ________.
A) travel to the thalamus and synapse on third-order neurons
B) transmit motor information from a receptor to the central nervous system
C) carry sensory information from a receptor to the central nervous system
D) travel from the thalamus to the cerebral cortex

Accepted Answer

First-order neurons are sensory neurons that carry sensory information from receptors (such as in the skin, muscles, or organs) to the central nervous system. They transmit this information to second-order neurons, which then relay the information to the thalamus, spinal cord, or brainstem.
