Cranial Nerves

Front 1

Cranial Nerve I.
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 1

Name: Olfactory Nerve
Function: Registers smells by carrying the impulses for the sense of smell from the nose to the Brain.

Purely a Sensory Nerve

Front 2

Cranial Nerve II
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 2

Name: Optic Nerve
Function: Optic nerve carries the impulses formed by the retna. These impulses are routed through the optic nerve to the brain.

This is a Sensory Nerve.

Front 3

Cranial Nerve III
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 3

Name: Oculomotor Nerves
Function: Responsible for the nerve supply to muscles around the eye.
The upper eyelid muscle which raises the eyelid.
The Extraocular muscle which moves the eye inward.
The papillary muscles which constricts the Pupil.

This is a Motor Nerve.

Front 4

Cranial Nerve IV
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 4

Name: Trochlear Nerve
Function: Controls the superior oblique muscle of the eye.

A Motor Nerve

Front 5

Cranial Nerve V
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 5

Name: Trigeminal Nerve
Function: Provides sensory information from the face, forehead, nasal cavity, tongue, gums and teeth (touch, and temprature).
Provides Somatic motor innervation to the muscles of mastication or "Chewing".

So it is a Mixture of both sensory and motor nerves.

Front 6

Cranial Nerve VI
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 6

Name: Abducens Nerve
Function: Supplies a muscle called the lateral rectus muscle that moves the eye outward.

Purely Motor Nerve.

Front 7

Cranial Nerve VII
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 7

Name: Facial Nerve
Function: Motor innervation to the many muscles for facial expression.
Sensory activity from the face and taste information from the anterior 2/3 of the tongue.

Mixed sensory and motor nerve.

Front 8

Cranial Nerve VIII
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 8

Name: Vestibulocochlear Nerve/ Auditory Nerve
Function: Responsible for the sense of hearing and which is also relevant to balance, to the body position sense.

Purely sensory

Front 9

Cranial Nerve IX
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 9

Name: Glossopharyngeal Nerve.
Function: Supplies the tongue, throat and one of the salivary glands.
Carries Sensory Data suach as touch , temperature, and pressure from the pharynx and soft palate.
It carries taste sensation from the taste buds on the posterior 1/3 of the tongue.
It provides somatic motor response to the throat muscles involved in swallowing.
It provides visceral motor activity to the salvary glands.
It also supplies the carotid sinus and reflex control to the heart.

Composed of both sensory and motor nerves.

Front 10

Cranial Nerve X
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 10

Name: Vagus Nerve
Function: Supplies nerve fibers to the pharynx, larynx, trachea, lungs, heart, esophagus, and the intestinal tract.
The Vagus nerve also also brings sensory information back from the brain from the ear, tongue, pharynx, and larynx.
Provides visceral motor signal to the heart, stomach, intestines, and gallbladder.
It is part of the parasympathetic branch.

It is composed of both sensory and motor nerves.

Front 11

Cranial nerve XI
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 11

Name: Spinal accessory Nerve.
Function: Spinal branch supplies the sternocliedomastoid muscle, it is in the front of the neck and turns the head.
The Trapezius muscle moves the scapula, turns the face to the opposite side, and helps pull the head back.

Cranial branch provides somatic motor innervation to some of the muscles in the throat involved in swallowing.

Purely a motor nerve.

Front 12

Cranial Nerve XII
Name of the nerve.
Describe the function, Identify if sensory, motor, or mixed.

Back 12

Name: Hypoglossal nerve
Function: Supplies the muscles of the tongue.

It is a motor nerve.
