What type of nerve is the Hypoglossal nerve classified as?

The Hypoglossal nerve is classified as a motor nerve because its primary function is to innervate the muscles of the tongue, which are responsible for movements necessary for speech and swallowing. This nerve controls motor functions specifically, allowing for the precise movements of the tongue that are critical in articulating sounds and in the manipulation of food during chewing and swallowing. It does not carry sensory information, which differentiates it from sensory and mixed nerves. Sensory nerves carry sensory signals to the brain, while mixed nerves contain both motor and sensory fibers. The Hypoglossal nerve does not have sympathetic functions, which would be associated with autonomic control. Therefore, its clear and focused role in motor function makes it a pure motor nerve.
