Cranial Nerves
What cranial nerves carry parasympathetics?
3, 7, 9, 10
(3,7,9 associated with COPS ganglion; X carries parasympathetics to the abdomen)
The combined action of what two muscles causes a downward gaze?
Superior oblique and inferior rectus
What muscle allows you to pull liquid through a straw?
Buccinator
(Note: the buccinator pulls in the cheeks; the orbicularis oris closes the mouth/puckers the lips)
What is found in the carotid sheath?
Common carotid artery, vagus nerve, jugular vein
What are the parent nerves of each distinct Zygomatic nerve? (DOUBLE points if player can name fiber type/modality of each)
Branch of Infraorbital nerve from Maxillary Nerve (CN V2) - VISCERAL MOTOR (to lacrimal glands via communicating branch), GENERAL SENSE
What modalities (general sensory, special sensory, somatic motor, visceral motor) are carried by the oculomotor nerve (CN III)
Somatic Motor (eye muscles)
Visceral Motor
Name the two branches AND origin of the frontal nerve.
Supratrochlear, Supraorbital
Trigeminal Division V1
What muscle is responsible for opening the jaw?
Lateral Pterygoid
Depression of mandible: Lateral pterygoid + gravity
Elevation of mandible: masseter, medial pterygoid, temporalis
What muscle is innervated by the external laryngeal nerve?
Cricothyroid
What muscles do Tyler's place and Maisie's fold correspond to?
Tensor (veli) palatini [CN V3] and levator (veli) palatini [CN X].
Where are the cell bodies associated with the general/special sensory aspects of facial nerve (CN VII)
Geniculate Ganglion
What two muscles compose the iris?
Sphincter and Dilator Pupillae
What nerve carries sensory information for the teeth of the mandible?
Inferior alveolar nerve.
What innervates each belly of the digastric muscle?
Ant belly: V3 via n. to mylohyoid
Post belly: Facial Nerve
Show me the function of the genioglossus.
*sticks out tongue
What is the facial nerve's general sensory territory?
In/Around Ear
(Note: you do NOT need to know the specific nerve name here)
What type of fiber is synapsing in the ciliary ganglion?
Pre-ganglionic parasympathetics with post-ganglionic parasympathetics
(non-synapsing: general sense V1 and just passing through, en passant = sympathetics)
What is contained (arteries/nerves) in the inferior orbital fissure?
Infraorbital a
Infraorbital n (branch of V2)
Zygomatic n (branch of V2)
(note: the infraorbital n + a continue through the infraorbital foramen)
What are the three vertical muscles of the pharynx?
Salpingopharyngeus (CN X), palatopharyngeus (CN X), stylopharyngeus (CN IX)
What fibers does the lesser petrosal nerve carry?
Pre-ganglionic, parasympathetic
Name 2 branches of the Maxillary division of Trigeminal (V2)
Superior posterior alveolar, nasopalatine, descending palatine, pharyngeal, infraorbital.
Which intraocular muscle is under sympathetic control?
Dilator Pupillae
What 7 bones contribute to the bony orbit?
Frontal, Maxilla, Zygomatic, Lacrimal, Ethmoid, Sphenoid, Palatine
What are the nerve roots of the Ansa Cervicalis?
C1-C3 Ventral Rami
What artery traverses the foramen spinosum? What is the parent artery? What is the grandparent artery?
Middle Meningeal artery from maxillary a from external carotid a.
