Question 6

which veins join together to form the retromandibular vein?

Answer 6

The maxilary (Coming via pterigoid plexus) and the superficial temporal

Question 7

Which veins join to form the common facial vein?

Answer 7

The facial vein and the anterior division of the retromandibular vein

Question 8

What two veins join to form the external jugular vein?

Answer 8

The posterior branch of the retromandibular and the posterior auricle veins

Question 9

What are some possible paths tha would allow the spread of infection from the superficial face into the brain?

Answer 9

The angular vein has connections with the superior opthalmic, which connects to coronary sinus which connects to dural venous sinus = meninges. The deep facial vein connects to the pterigoid plexus which connects to the inferior opthalmic which connects to the coronary sinus etc.

Question 10

What are the branches of the facial nerve?

Answer 10

Posterior Auricle, Temporal, Zygomatic, bucal, marginal mandibular, cervical

Question 11

What innervates the parotid gland?

Answer 11

Glossopharyngeal nerve (CN IX) via the auriculotemporal branch of V3

Question 12

What are the three divisions of trigem and what foramen do they exit on the face?

Answer 12

V1 - (opthalmic) supratrochlear nerves exit via the supraorbital foramen. V2 (maxilary)- Infraorbital nerve exits via the infraorbital foramen. V3 (mandibular)- Mental Nerve exits via the mental foramen

Question 13

What is the foramen that the facial nerve exits before entering the parotid gland?

Answer 13

the stylomastoid foramen

Question 14

What are some tell tale signs of bells palsy?

Answer 14

Lost of blink reflex and unilateral facial paralysis. crocodile tears.

Question 15

What are the boundaries of the infratemporal fossa?

Answer 15

Anteriorly, the posterior border of the maxila, laterally the ramus of the mandible, posteriorly the mastoid and styloid processes of the temporal bone, and medially the leteral pterygoid plate

Question 16

What is contained within the infratemporal fossa?

Answer 16

Lateral and medial pterygoid muscles, maxillary artery, pterygoid venous plexus, and the mandibular division of trigem (V3)

Question 17

What are the four muscles of mastication? Which is the only one involved in opening the mouth?

Answer 17

Masseter, temporalis, lateral and medial pterygoid

Lateral pterygoid is the only one that is involved in opening mouth.

Question 18

What is one of the most important branches of the maxillary artery, what does it supply, and how does it get there?

Answer 18

The middle meningeal artery travels through the foramen spinosum to supply the dura of the brain, injury can cause epidural hematoma via fracture of the squamous portion of the temporal bone. Blood could also drain through the foramen magnum and compress the brain stem

Question 19

What are the tiny connections between the pterygoid venous plexus and the caverous sinus and deep facial veins called?

Answer 19

emissary veins.

Question 20

How does the mandibular division of trigem make its way into the infratemporal fossa? What is unique about this division?

Answer 20

The foramen ovale. It has MOTOR fibers.

Question 21

What are all of the muscles of mastication innervated by?

Answer 21

CN V3

Question 22

What other sensory does CN V3 supply?

Answer 22

Dermatome of CN V3, mucosa lining of inside of the cheek, the teeth and gingiva of the mandible, anterior 2/3 of the tongue (pain) and capsule of the parotid gland.

Question 23

How is the CN V3 involved in taste?

Answer 23

It carries taste sensation from the facial nerve (CN VII) via the corda tympani along its own lingual nerve to the anterior 2/3 of the tongue

Question 24

When the jaw is anteriorly dislocated, the condyle of the mandible becomes struck anterior to what?

Answer 24

The articular tubercle of the temporal bone.

Question 25

How is CN V3 involved in secretomotor fn?

Answer 25

the auriculotemporal branch receives parasympathetics from CN IX that innervate the parotid. The lingual receives parasympathetics from CN VII that innervate the sublingual and submandibular glands.
