Craneal Nerves

Function

Its function is sensitive

It is responsible for driving the olfactory impulses from the nose to the central nervous system.

Apparent Origin

Olfactory Bulb:
lower face of the frontal lobe

Function

Send the signals that the eye perceives to our brain

Apparent Origin

Optic chiasma:
frontal lobe

Function

It has motor and parasympathetic functions

Motor:It is one of the nerves that controls eye movement

Parasympathetic: Responsible for pupil size

Apparent Origin

This nerve emerges in the common ocular motor groove located on the inside of the brain peduncles.

Function

Innervates the upper oblique muscle of the eye

Apparent Origin

Posterior face of the mesencephalic
inferior to the quadrilateral colicules

It has three main branches

Olfactory nerve

Maxillary nerve

Mandibular nerve

Function

It is a nerve with mixed function (motor and sensitive)

Mainly controls the chewing musculature and facial sensitivity

Apparent Origin

Anterolateral side of the bridge
(lateral fossa)

Function

It innervates the lateral rectus muscle of the eyeball, being responsible for turning the eye outward

Apparent Origin

Bulboprotuberancial groove at the level of the pyramids

Function

It is mainly responsible for coordinating language movements

Apparent Origin

Preolivar groove

Function

Controls sternocleidomastoid
muscles and trapezius

Apparent Origin

It leaves the skull through the jugular
hole along with the glossopharyngeal
and the vagus.

Function

Provides innervation to most laryngeal muscles

Carries parasympathetic fibers to the abdominal viscera

Receive the sense of taste from the epiglottis

Apparent Origin

Side groove of the bulb, between the olive bulbar and the inferior cerebellar peduncle

Function

Receive taste impulses from the posterior third of the tongue

Provides secret-motor innervation to the parotid gland and motor innervation to the stylopharyngeal muscle

Apparent Origin

Emerges from the posterior collateral groove of the medulla oblongata

Function

It is in charge of balance and auditory functions

Apparent Origin

Side angle of bulboprotuberancial groove

Function

It is a mixed nerve, with mainly motor function and with a sensitive portion

Collect taste impressions of the previous two thirds of the language

Apparent Origin

Bulboprotuberancial groove at olive level
