Lab Practical 3 Flashcards
Filaments of the olfactory nerve (I)
Sensory, carries afferent impulses for senses of smell
Optic Nerve (II)
Sensory, carries afferent impulses associated with vision
Oculomotor Nerve (III)
Motor, motor fibers to direct eyeball
Trochlear Nerve (IV)
Motor, provides somatic motor fibers to superior oblique muscle that moves eyeball
Trigeminal Nerve (V)
Mixed, sensory nerve of face, motor nerve that innervate muscles of mastication
Abducens Nerve (VI)
Motor, somatic motor fibers to lateral rectus muscle to abduct eyeball
Facial Nerve (VII)`
Mixed, sensory fibers from taste receptors of tongue, motor fibers for facial expression
Vestibulocochlear Nerve (VIII)
Sensory, vestibular branch- > associated with sense of equilibrium, cochlear branch transmits impulses associated with hearing
Glossopharyngeal Nerve (IX)
Mixed, sensory fibers from pharynx, tonsils, taste buds; motor fibers pharyngeal muscles
Vagus Nerve (X)
Mixed, sensory and motor fibers associated with pharynx and larynx,
Accessory Nerve (XI)
mixed, primarily motor, provides motor fibers to trapezius and sternocleidomastoid
Hypoglossal Nerve (XII)
mixed, primarily motor; provides motor fibers to muscles of the tongue
