🗑
|
||||
| show | Arises from the olfactory epithelium
Functions solely by carrying afferent impulses for the sense of smell
🗑
|
||||
| show | Arises from the retina of the eye
Functions solely by carrying afferent impulses for vision
🗑
|
||||
| Cranial Nerve III: Oculomotor | show 🗑
|
||||
| show | Fibers emerge from the dorsal midbrain and enter the orbits via the superior orbital fissures; innervate the superior oblique muscle
Primarily a motor nerve that directs the eyeball
🗑
|
||||
| Cranial Nerve V: Trigeminal | show 🗑
|
||||
| show | Fibers leave inferior pons and enter orbit via superior orbital fissure to run to eye
Controls the extrinsic eye muscle that abducts the eyeball (turns it laterally)
🗑
|
||||
| show | Mixed nerve with five major branches
Motor functions include facial expression, and the transmittal of autonomic impulses to lacrimal and salivary glands
Sensory function is taste from the anterior two-thirds of the tongue
🗑
|
||||
| show | inner ear, pass through the internal acoustic meatus, and enter the brainstem at the pons-medulla border
Two divisions – cochlear (hearing) and vestibular (balance)
Functions are solely sensory – equilibrium and hearing
🗑
|
||||
| show | Motor – innervates part of the tongue and pharynx, and provides motor fibers to the parotid salivary gland
Sensory – fibers conduct taste and general sensory impulses from the tongue and pharynx
🗑
