ASSESSMENT I N ANATOMY

Concerning viewing the head in norma lateralis

a. Lambda is at junction of lambdoid and sagittal sutures

b. Bregma is at junction between sagittal sutures and vertex

c. Nasion point where frontonasal and internasal sutures meet

d. Asterion is located at the junction of three suturese. Most prominent point on external occipital protuberance is the Nasion

Concerning the superior aspect of the head

a. The coronal suture separates frontal and temporal bones

b. The sagittal suture separates the parietal bones

c. The vertex is found near the midpoint of the lambdoid suture

d. Located near the sagittal suture posteriorly, a parietal foramen can be seen

e. Occasionally, an emissary foramen may be present

Concerning the external surface of the cranial base

a. Hard palate is formed by the maxilla and the vomer

b. The choanae are separated from each other by the vomer

c. Spinal accessory nerve (CN XI) pass through foramen magnum

d. Anterior and posterior spinal arteries course in the foramen magnum

e. The jugular foramen transmits the internal carotid artery and vein

and CN IX, X, and XI

Concerning the foramina of the cranial fossae

a. Foramen cecum may transmit the nasal emissary vein

b. Foramen rotundum transmits the mandibular nerve

c. Foramen spinosum transmits the accessory meningeal artery

d. Foramen lacerum transmits the greater petrosal nerve

e. Foramen ovale transmits the middle meningeal artery and vein

Concerning the face

a. All muscles of facial expression are derived from the third branchial arch

b. The frontalis muscle inserts into the Galea Aponeurotica

c. Buccal and retroorbital fat pads are first fat stores to be depleted

d. The facial artery is one of the principle branches given off the

external carotid.

e. Facial artery pulse can be palpated as the artery crosses the mandible

just anterior to the buccinator muscle

f. The supraorbital and supratrochlear arteries arise from the internal

carotid artery

g. Superior ophthalmic vein is a communication between the Facial vein

Concerning the cranial fossae

a. Anterior cranial fossa houses frontal lobes

b. Posterior cranial fossa houses occipital lobes,

cerebellum, and pituitary

c. Middle cranial fossa includes the lesser wing ofthe sphenoid, sella turcica, and the majority of

temporal bones

d. Posterior cranial fossa includes the temporal

bone.

e. Anterior cranial fossa includes all of frontal and

ethmoid bones, and the lesser wing of the

sphenoid

Concerning the triangles of the neck

a. The cricoid cartilage forms the laryngeal

prominence, or Adam's apple

b. Carotid sheath contains common carotid artery,

internal jugular vein and vagus nervec. That part of the anterior triangle inferior to the

spinal accessory nerve is called the danger zone

d. The union of the retromandibular and posterior

auricular veins forms the external jugular vein

e. Most of the facial veins drain into the internal

jugular vein

f. Thyroid gland,trachea and esophagus are contained

in the prevertebral fascia

g. Platysma forms the posterior border the posterior

triangle

Concerning the anterior triangle of the neck

a. The superior belly of the omohyoid is the medialborder of the Carotid triangle

b. The sternocleidomastoid is the lateral border of

the Carotid triangle

c. The posterior belly of Digastric forms the medial

border of the submandibular/digastric triangle

d. Digastric, mylohyoid, hyoglossus are found in the

submandibular triangle

e. It is subdivided into muscular, submandibular and

carotid triangles

and the Cavernous Sinus

Concerning the facial artery

a. It is given off just deep to the angle of the mandible

b. It crosses the inferior border of the mandible just anterior to the buccinator

c. Superior labial branch above has anastomoses with the ophthalmic artery

d. Angular Artery has anastomoses with the infraorbital artery

e. Passes at the inner canthus (medial corner) of the eyef. The mental artery arises from mental foramen and supplies the chin

Concernig the veins of the face

a. The facial vein is formed from the supraorbital and supratrochlear veins

b. The retromandibular vein is formed by the union of the superficial

temporal vein and the mandibular vein

c. Deep facial vein is a communication between the facial vein and the

pterygoid plexus

d. Superior ophthalmic vein is a communication between the facial vein

and the cavernous sinus

e. Superficial veins communicate with dural sinuses in the danger triangleConcerning the facial muscles

a. Orbicularis oculi (orbital sphincter) closes

eyelids

b.Mentalis depresses mandible (againstresistance)

c. Platysma elevates and protrudes lower lipd. Zygomaticus major and levator anguli oris are

involved in smile and disdain

e. Risorius is involved in grinning or grimacing

f.Depressor anguli oriscauses us to frownConcerning the innervation of the face

a. CN V is the sensory nerve for the face and

the motor nerve for the muscles of mastication

b. Ophthalmic and mandibular nerves are wholly

sensory

c. Maxillary nerve receives the motor fibers

(axons) from the motor root of CN V

d. CN V1 is the largest division of the three

divisions of CN V

e. CN V1 enters the orbit through the inferior

orbital fissure

f. CN V1 trifurcates into the frontal, nasociliary,

and lacrimal nerves

Concerning the innervation of the face

a. The frontal nerve divides within the orbit into

the posterior ethmoidal, anterior ethmoidal, and

infratrochlear nerves
