meddula, pons, midbrain

(diencephalon is not, according to Susan)

• vegetative functions: circulation, respiration, digestion, sleep/wakefullness
• houses cranial nerves
• contains ascending and descending fibers from spinal cord and cortex, also in and out of cerebellum
• rhythmic and crude voluntary motor control

• numbered according to rostral-caudal position
• all cranial sensory neurons are neural crest derived except (I & II)
• cranial motor neurons are basal plate, nueral tube derived.
• closer to medulla (caudal) = more resemblance to spinal nerves
• I, II, VIII: pure sensory
• III, IV, VI, XI, XII: pure motor
• V, VII, IX, X: mixed

• terminates in olfactory bulb within nasal cavity (goes through bone!)
• contains axons of sensory nerves derived from neural TUBE--> 
• telecephalon--> rhinencephalon, specifically 
• regarded as a special sensory nerve

• develops from diencephalon, innervates retina
• contains sensory nerves originating from neural TUBE cells.
• regarded as a special sensory nerve

• first of three nerves that controls eye muscles for movement--> Somatic Motor
• Also Visceral Motor: controls ciliary, iris, sphincter eye muscles, used for lens accomodation and pupil dilation

second of the three nerves used for eye muscle movement

Sensory Motor: moves superior oblique muscle

• thrid of three nerves for eye movement
• Somatic Motor: moves lateral rectus muscle of eye

• main somatosensory afferent (SA) in front portion of face (sinuses, teeth)
• Somatic Motor (SE)-- motor muscles for chewing (mastication)

Somatic Motor: muscles for facial expression

Visceral Motor: lacrimation and salivation

Visceral Sensory: taste on the anterior 2/3rds of tongue.
