Nerves Flashcards
OCULOMOTOR NERVE (III) PARASYMPATHETIC (Visceral motor) Where’s the ganglion?
to constrictor pupillae and ciliary muscles Parasympathetic fibers of the oculomotor nerve synapse in the Ciliary Ganglion
TROCHLEAR NERVE (IV) – Somatic Motor to the… ABDUCENS NERVE (VI) - Somatic Motor to the…
superior oblique m. lateral rectus m.
ACCESSORY NERVE (XI) – Branchial Motor to the…
trapezius and sternocleidomastoid muscles
HYPOGLOSSAL NERVE (XII) – Somatic Motor to all tongue muscles, except…
the palatoglossus muscle
BRANCHIAL MOTOR of V – contained only in V3 are motor too
MUSCLES OF MASTICATION: OTHER MUSCLES: Tensor tympani, tensor veli palatini, mylohyoid, anterior belly of digastric muscles
GENERAL SENSORY – contained in V1, V2 and V3. Principal general sensory for all of the head. 1st order sensory neurons relay to 2nd order sensory neurons in the following Trigeminal sensory nucleii:
Mesencephalic nucleus (Midbrain) - muscle proprioception
Pontine Trigeminal nucleus (Pons) - touch
Nucleus of spinal tract (Pons – Spinal cord)- pain and tempurature

V2 BRANCHES IN THE PTERYGOPALATINE FOSSA
To the Pallet?
- Greater palatine nerve – hard palate distal to canines
- Lesser palatine nerve – soft palate
- Nasoopalatine nerve – nasal septum and hard palate
V2 BRANCHES IN THE PTERYGOPALATINE FOSSA
To the face?
-
Zygomaticofacial – skin over zygomatic arch
- Zygomaticotemporal – skin over ant. temple
- Zygomatic nerve - enters the orbit to branch into two nerves:
