Olfactory
Sensory
smell
Optic
Sensory
vision
Oculomotor
Motor
moves eye upward, downward, medial
Trochlear
Motor

Trigeminal
Both motor and sensory
Sensations of head, face, chewing movements, proprioception
Abducens
Motor
Abduct eye, proprioception
Facial
Both
receptors are the taste buds of 2/3 anterior of the tongue
Function: FAcial expressions, secretion of saliva and tears, taste
Vestibulocochlear(Acoustic)
Balance or equilibrium sense(vestibular)
cochlear- hearing
Glossopharyngeal
both
Receptors: Pharynx; taste buds and other receptors of posterior 1/3 of the tongue
Function: Sensations of tongue, swallowing movements, secretion of saliva, various reflexes, control of BP and respiration
Vagus
Both
Receptors: Pharynx, larynx, carotid body, thoracic and abdominal viscera
Function: slows heart rate, increases peristalsis/digestion, contracts muscles for voice production
Spinal Assesory
MOTOR
Receptors: Trapezius and SCM
Function: “Shoulder shrug” Shoulder movements, turning movements of head, proprioception
Hypoglossal
MOTOR
Tongue movements, proprioception
