Question 13

Olfactory nerve

Answer 13

-function: smell
-from olfactory epithelium
-olfactory foramen
-goes to the olfactory bulb

Question 14

Optic nerve

Answer 14

-vision
-from the retina
-the foramen is the optic canal
-goes to the diencephalon then to occipital lobe

Question 15

Nerves 3 4 and 6

Answer 15

Move eye ball

Question 16

Oculomotor nerve

Answer 16

-control eye movement/ eye muscles
-from the mesencephalon
-foramen is the superior orbital fissure
- goes to the extra ocular eye muscles

Question 17

Trochlear nerve

Answer 17

-control eye muscles
-from the mesencephalon
-foramen is the superior orbital fissure
-goes to the extra ocular eye muscles

Question 18

Trigéminal nerve

Answer 18

-facial sensation of ophthalmic (sensation from forehead to eyeballs), maxillary (lower eyelid upper lip and cheek)and mandibular (mastication and teeth sensation)
-from the opthalmic, maxillary and mandibular nerves
-superior orbital fissure, foramen rotundamente and foramen Ovalle
-maxillary and opthalmic goes to the pons
-mandibular goes to masseter and temple

Question 19

abducens nerve

Answer 19

-control eye movements
-originate at the pons
-superior orbital fissure (slit in the back of they eye)
-goes to the lateral rectus eye muscle

Question 20

facial nerve

Answer 20

-moves all muscles except the chewing muscles
-sensation of the face, taste on the front 2/3 of tongue, control muscles of the face
-from the taste buds (sensory) and the pons (motor)
-internal acoustic meatus
-sensory goes to the pons and motor foes to muscles of the face
-2 major branches

Question 21

vestibulocochlear nerve

Answer 21

-for balance and hearing
-cochlea is hearing in the ear vestibule is balance
-from the vest. and cochlea
-internal acoustic meatus
-goes to the pons

Question 22

smalles bone in the body

Answer 22

ossicles

Question 23

glossopharyngeal nerve

Answer 23

-tongue pain and swallowing
-back half of the tongue
-taste in back of the tongue
-from the salivary gland
-jugular foramen
-goes to the pons (sensory), parotid salivary gland (visceral motor) and pharyngeal muscles to swallow (somatic motor)

Question 24

vagus nerve

Answer 24

-info from organs (sensory) and sends info to organs (motor)
-from the organs or medulla oblongota (motor)
-also swallowing
-jugular foramen
-sensory goes to medulla oblongota
-somatic motor goes to palate and pharynx muscles
-visceral motor goes to respiratory cardiovascular and digestive organs

Question 25

accessory nerve

Answer 25

-control sternocleidomastoid, trapezius, palate, pharynx, larynx muscles
-from the spinal cord and medulla oblongota
-jugular foramen
-internal and external branch
-int branch goes to muscles of the palate, pharynx, and larynx
-ext. goes to sternocleidomastoid and trapezius muscles

Question 26

hypoglossal nerve

Answer 26

-control tongue movement
-from the medulla oblongota
-hypoglossal canal
-goes to tongue muscles
