____________ (direct and consensual reflexes) by flashing a light
sensory is CN ___ and motor is CN ___ that will produce pupillary constriction
Pupillary reflex
sensory is CN II
motor is CN III
MESENCEPHALON: Midbrain
CN which has no nucleus because it is CN I (OLFACTORY) AND CN II (OPTIC) because it is __________
cortical
DIENCEPHALON
sensory and motor relay to the cerebral cortex
visual inputs (CN II)
are of higher center responsbile for maintenance of consciousness
thalamus

generally made up of pineal gland
concerned with the sleep-wake cycle
responsible for biologic rhythm
epithalamus
