Question

multiple choice question
what type of fibers are found in the anterior root of a spinal nerve?
-
o the axons of motor neurons
o the axons of both sensory and motor neurons
o the axons of sensory neurons

Explanation:

To determine the type of fibers in the anterior root of a spinal nerve, we recall the anatomy of spinal nerves. The anterior (ventral) root of a spinal nerve contains the axons of motor neurons, which are responsible for transmitting motor signals from the spinal cord to muscles or glands. Sensory neurons' axons are found in the posterior (dorsal) root. So the anterior root has only motor neuron axons.

Answer:

A. The axons of motor neurons
