multiple choice
what type of fibers are found in spinal nerves?
options:

• both motor and sensory neurons
• motor neurons only
• sensory neurons only

Explanation:

Spinal nerves are mixed nerves, meaning they contain both motor (efferent) fibers that transmit signals from the central nervous system to muscles/glands and sensory (afferent) fibers that transmit sensory information from the periphery to the central nervous system. So spinal nerves have both motor and sensory neuron fibers.

Answer:

Both motor and sensory neurons
