what type of fibers are found in spinal nerves?
multiple choice
sensory neurons only
both motor and sensory neurons
motor neurons only
Spinal nerves are part of the peripheral nervous system. They originate from the spinal cord. Motor neurons carry signals from the central nervous system (brain and spinal cord) to effectors (muscles and glands). Sensory neurons carry signals from sensory receptors (e.g., in skin, eyes, ears) to the central nervous system. Spinal nerves have a dorsal root (sensory fibers entering the spinal cord) and a ventral root (motor fibers leaving the spinal cord). When these roots combine to form a spinal nerve, it contains both motor and sensory neurons.
