a
a motor & autonomic nerve that controls muscles that move the eye, lift eyelid, change pupil diameter, change lens shape. Comes from midbrain.
Oculomotor
mixed nerve - motor and sensory - it has autonomic function. Carries information taste on the posterior 1⁄3 of tongue, stimulates parotid glands to make saliva, one pharyngeal muscle. Comes from medulla oblongata.
Glossopharyngeal nerve
(smell) sensory only
olfactory
vision - sensory functions only
optic nerve
CN V
trigeminal nerve
a motor nerve that controls superior oblique eye muscle. Comes from midbrain.
Trochlear
mixed nerve motor and sensory - it has autonomic functions. Main parasympathetic nerve in your whole body - visceral sensory info from heart, lungs, most abdominal organs. Somatosensory from ears and throat. Innervates smooth muscle and glands of the heart, lungs, larynx trachea and most abdominal organs. Comes from medulla oblongata.
Vagus Nerve
nerves with sensory functions only
olfactory
optic
vestibulocochlear
hypoglossal nerve
CN XII
trochlear nerve
CN IV
Mixed nerve motor and sensory. it has 3 branches mandibull, maxillary and ophthalmic branch. Sensory for feeling on the face, sensation from your teeth, biting tongue and external ear and even meninges. Border of midbrain and pons.
Trigeminal nerve
motor nerve, that controls intrinsic and extrinsic tongue muscles. Comes from medulla oblongata.
Hypoglossal nerve
nerves with motor functions only
trochlear
abducens
accessory
hypoglossal
oculomotor (with autonomic functions)
VAGUS NERVE
CN X
CN VII
facial nerve
Motor nerve that controls lateral rectus muscle that abducts the eye. From pons.
Abducen Nerve
sensory nerve - involved in hearing and equilibrium. Comes from medulla oblongata.
Vestibulocochlear nerve
nerves with mixed functions & what the functions are
oculomotor (motor and autonomic)
trigeminal (sensory and motor)
facial (sensory, motor and autonomic)
glossopharyngeal (sensory, motor and autonomic)
Vagus (sensory, motor and autonomic)
CN II
optic nerve
CN VIII
vestibulocochlear nerve
Mixed nerve motor and sensory - it has autonomic functions - transmits taste sensation from anterior 2⁄3 of the tongue, relays motor output to muscle of facial expression lacrimal, tear and gland and salivary glands. Comes from the pons.
Facial nerve
motor nerve that controls muscles of the neck, pharynx. Innervates sternocleidomastoid muscle and trapezius muscle. Comes from medulla oblongata.
Accessory nerve
CN I
olfactory
CN III
glossopharyngeal nerve
CN IX
