CN IX is innervated bilaterally and has sensory, parasympathetic, and motor components. Two of the cranial nerves receive innervation from only one side of the brain (the contralateral side): CN XII (hypoglossal which innervates the tongue) and CN VII (facial which innervates the muscles of the face). The corticobulbar tract also contributes to the motor regions of cranial nerve X in the nucleus ambiguus. The peripheral nervous system (PNS) is one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system (CNS). This article will explore the functions of the cranial nerves and provide a diagram. Cranial Nerves. 2. Twelve pairs of nerves (the cranial nerves) lead directly from the brain to various parts of the head, neck, and trunk. This means that both the left and right side of a pair of cranial nerves are innervated by the cortex of both the left and right hemispheres. Solution for All cranial nerves receive bilateral innervation from the cortex with the exception of The functions of the cranial nerves are 15 The sensory division receives general sensory fibers from the tonsils, pharynx, middle ear, and the The axons from the motor neurons create the lateral thoracic nerve, which innervates the cutaneous trunci muscle.
