C. temporal, zygomatic, mandibular
D. Opthalmic, temporal, mandibular
A. Ophthalmic, maxillar, mandibular
Which nerve conveys sensory impulses from various areas of the face (V1) and (V2), and supplies motor fiers (V3) for mastication?
A X Vagus
B V Trigeminal
C III Oculomotor
D VII facial
B. V Trigeminal
Cranial nerve VI Abducens is:
A a motor nerve innervating the lateral rectus
muscle
B sensory in taste
C head and neck
A a motor nerve innervating the lateral rectus
muscle
Cranial Nerve VII has both sensory and motor functions.. What is the motor function and what is the sensory function?
A motor-swallowing sensor-hearing
B motor-direct the eyeball/ sensory-hearing
C motor-facial expression/Sensory-taste from the anterior two-third of the tounge
C. motor-facial expression/Sensory-taste from the anterior two-third of
the tounge
This nerve functions soley sensory-providing equilibrium and hearing
A III oculomotor
B XII Hypoglossal
C X Vagus
D VIII Vestibulocochlear
D VIII Vestibulocochlear
- This nerve is a mixed nerve with motor and sensory functions, Motor function is to innervate part of the tongue and pharynx, and provide motor fibers to the parotid salivary gland Sensory funtion is conduct
taste and general sensory impulses from the tongue and pharynx
A III oculomotor
B V Trigeminal
C IX Glossopharyngeal
D X Vagus
C IX Glossopharyngeal
