The 12 sets of efferent fibers that exit the CNS directly from the brain rather than from the spinal cord. In order they are: Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Aducens, Facial, Vestibulocochlear, Glossopharyngeal, Vagus, Accessory and Hypoglossal nerves.
Nerves that carry sensory or motor fibers to the face and neck. Included among this group of 12 nerves are the optic nerve (vision), trigeminal nerve (sensation along the face), vagus nerve (pharynx and vocal cord). Evaluation of cranial nerve function is part of the standard neurologic exam.
The twelve pairs of "nerves" that are directly connected to the brain. They are the nervi olfactorii(I), opticus(II), oculomotorius(III), trochlearis(IV), trigeminus(V), abducens(VI), facialis(VII),vestibulocochlearis(VIII),glossopharyngeus(IX), vagus(X), accessorius(XI),and hypoglossus(XIII). The olfactory "nerve" and the optic "nerve" are actually post-synaptic tracts with glial cells like astrocytes and oligodendrocytes, rather than Schwann cells. image
The twelve pairs of nerves that enter and exit directly from the hindbrain. These nerves control movements of the head and neck, carry sensations from them including vision, olfaction, and audition, and regulate the various glandular secretions in the head.
12 pairs of nerves that carry information to and from sense organs, muscles and internal organs. The cranial nerves include: olfactory nerve (smell), optic nerve (sight), oculomotor nerve (eye movement, dilation of pupil), trochlear nerve (eye movement), trigeminal nerve (sensation from the head and chewing muscles), abduccens nerve
Cranial nerves are nerves that emerge directly from the brain in contrast to spinal nerves which emerge from segments of the spinal cord. Conventionally, there are twelve recognized cranial nerves in humans. The nerves from the third onward arise from the brain stem.
