Crainal Nerves
The brain consists of 12 pairs of cranial nerves that derive from our brain and brain stem. These nerves's functions are crucial to different senses around the body. Some nerves even work with motor functions to control features on the face.
Olfactory Nerve:
This is a sensory nerve that functions with the sense of smell. This nerve provides olfactory epithelium cells with connection to the brain.
Optic Nerve:
This is another sensory nerve except this nerve transforms information about vision to the brain. It supplies information to the retina in the form of ganglion cells.
Oculomotor Nerve:
This is a motor nerve that connects different midbrain areas. It controls functions such as eyelid movement, eyeball rotating, constriction of the pupil, and eye muscles.
Trochlear Nerve:
This is another motor never that helps control functions in the midbrain such as eye muscle movements and motor functions in the brain.
Trigeminal Nerve:
This is the largest cranial pair because it preforms many sensory and motor functions in the nose, eyes, tongue, and teeth. This nerve is so large it has three branches: ophthalmic, maxillary, and mandibular nerve.
Abducens Nerve:
Another nerve that controls motor functions to the pons and controls the function of laterally turning the eye.
Facial Nerve:
This nerve serves important motor functions in the face. It is responsible for creating different types of facial expressions. It also supplies sensory information about senses in the face and tongue.
Vestibulcochlear Nerve:
This nerve controls motor information relating to balance of the head and sense of sound/hearing. It carries vestibular and cochlear information to the inner ear in the brain.
Glossopharyngeal Nerve:
This sensory nerve carries information from the pharynx, normal size of throat, and proportions of tongue and palate. This nerve covers a portion of taste buds and salivary glands, this helps obtain information about temperature and pressure. This nerve also carries some motor function that helps with swallowing.
Vagus Nerve:
This is another nerve that mixes with motor and sensory functions. This nerve's motor functions is in the pharynx, larynx, esophagus, trachea, bronchi, and some areas of the hear and palate. The vagus nerve constricts the muscles in the states regions. The sensory aspect of this nerve is assisting in the ability to taste things.
Spinal Accessory Nerve:
This nerve supplies motor information about the spinal cord, trapezius and other surrounding back muscles which it provides movement for.
Hypoglassal Nerve:
The hypoglassal nerve has motor functions in the muscles of the tongue.
This is a sensory nerve that functions with the sense of smell. This nerve provides olfactory epithelium cells with connection to the brain.
Optic Nerve:
This is another sensory nerve except this nerve transforms information about vision to the brain. It supplies information to the retina in the form of ganglion cells.
