Front 10

Rise of the soft palate when phonating 'AAHH' is controlled by what cranial nerve?

Back 10

Glossopharyngeal (CN IX)

Front 11

Back 11

XII (Hypoglossal)

Front 12

2. Inferior rectus (down) CN III
3. Medial rectus (Inward) CN III
4. Lateral rectus (out) CN VI
5 Superior Oblique (in/down) CN IV

Front 14

What cranial nerve provides sensory innervation to the face? List the three branches of this nerve.

Back 14

Trigeminal Nerve (CN V)
-ophthalmic
-maxillary
-mandibular

Front 15

Describe the motor and sensory functions of the mandibula branch of the trigeminal nerve.

Back 15

Motor innervation (anterior) to the muscles of mastication (chewing)

Posterior branch provides sensory innervation to the lower teeth and gums.

Front 16

What nerve stimulates the sneeze reflex?

Back 16

trigeminal nerve CN V

Front 17

which cranial nerve is responsible for facial expression?

Back 17

CN VII supplies the muscles of facial expression

Front 18

Which cranial nerve controls ewuilibrium?

Back 18

vestibular branch of CM VIII

Front 19

Which nerve provides motor innervation to the tongue?

Back 19

CN XII - Hypoglossal

Front 20

How can damage to CN XII affect the aurway?

Back 20

Hypoglossal nerve is a motor nerve controlling the exxtrinsic and intrinsic muscles of the tongue. Damage can relax the tongue and cause it to fall back and obstruct the airway.

Front 21

What are the results of electrical stimulation to the reticular activating system?

Back 21

Increases alertness. and can even cause a sleeping individual to awaken instantaneously

Front 22

When are delta waves seen?

Back 22

Delta waves are seen during deep sleep or deep anesthesia.

Front 23

When are theta waves seen?

Back 23

Theta waves are seen during physiological sleep during GA in adults, and during hyperventilation in awake children.

Front 24

When are alpha waves seen?

Back 24

Seen during resting awake state with eyes closed or during sedation

Front 25

When are beta waves seen?

Back 25

Most appear during activation of the central nervous system 9during mental concentration ) and during light anesthesia

Front 26

In an EEG pattern, wat type of waves occur during surgical anesthesia?

Back 26

Delta waves occur during deep anesthesia
