WebDec 8, 2024 · The somatic motor fibers (efferent special visceral or branchial motor) arise from the cells of the nucleus ambiguus, which is the motor nucleus for striated muscles of the pharynx, larynx and palate in the middle of the upper part of the medulla. It is adjacent to the respiratory motor neurons in the brainstem. (See the image below.) WebA neuron is a single sensory or motor nerve cell, whereas a nerve is a bundle of neuronal fibers (axons). Cranial nerves have three types of sensory and three types of motor neurons, known as modalities. Therefore, a nerve may be composed of a combination of sensory or motor neurons (e.g., the facial nerve possesses sensory and motor neurons).

WebThe cell bodies of the sensory neurons are in the dorsal root ganglion, but the motor neuron cell bodies are in the gray matter. The two roots join to form the spinal nerve just before the nerve leaves the vertebral column. Because all spinal nerves have both sensory and motor components, they are all mixed nerves.
