| Function of the nerves; sensory or motor is to sense or supply muscles | Vagus is the longest; serves upper body and abdominal area.
🗑

| The nucleus of the nerves cross over at the optic chiasm. most of the nerves are in the area of the brain-stem | Olfactory nerves pass through holes in the cribriform plate and then to the olfactory bulb.
🗑
|
||||
| The olfactory tracts lead from these bulbs back to the thalamus and then to the frontal lobe for smell perception | Special Visceral Afferents;;Chemical senses taste and smell if no taste then no smell

| pathway of the optic nerve...optic tract--thalamus--visual cortex. Medial fibers cross, lateral fibers remain on same side (lateral same eye | Special senses only found in the head=Vision II, Hearing and Ballance VII
🗑

| Oculomoter parasympathetic fibers control muscles of iris for constricting pup. Controls extrinsic eye muscles Superior & Inferior rectus and Inferior oblique muscles. bilateral 6 total | Trochlear contsol the superior oblique muscle of the eye. Stabilizes eye. Pulley shaped. Between pons and the midbrain

| Trigeminal- Great sensory nerve of the head. largest nerve in the body. | Trigeminal-Three divisions: opthalmic, maillary and mandibular

| VII Facial leaves posterior cranial fossa via Internal Auditory Meatus---enters facial canal | Greater Petrosal N (Facial VII) forms Nerve of Pterygoid Canal
🗑
|

| Muscles of facial expression--1. Temporal - auricular 2. Zygomatic - muscles of the zygomatic arch . 3. Buccal - muscles in the cheek and above the mouth. 4. Mandibular - muscles in the region of the mandible. 5. Cervical - the platysma muscle | Pathway to lacrimal gland: Greater Petrosal N. to Pterygopalatine Ganglion to Lacrimal
🗑

| Lacrimal Gland-Post-ganglionic Parasymp. join Zygomatic to V1 Lacrimal | Pathway to mucus gland of nose, palate: Greater Petrosal N. to Pterygopalatine Ganglion to Musus Glands Nose , Palate via greater and lesser palatine N.
🗑

| Pathway to submandibular, sublingual , salviary glands, taste fibers to ant 2/3 tongue. Chorda typani around lingual nerve submandibular ganglion to tongue and glands | Greater Petrosal-mucus glands of nose and plalate form N. of Pterygoid Canal, synapse in Pterygoid Palatine Ganglion
🗑
