Veins of the Head and Neck

Question 1

Supraorbital vein anastomoses with branches of the ___

Answer 1

Superficial temporal vein. The supraorbital vein runs over the supraorbital margin, laterally, to join up with the superficial temporal vein.

Question 2

Branches of the supraorbital vein

Answer 2

1. Palpebral- drain blood from eyelids.
2. Diploic veins- drain from the diploe in forehead.
3. Frontal- drains from scalp of forehead
   * **4. Communication vein enters the orbital septum to become the superior root of the superior ophthalmic vein.

Question 3

The communication vein branches off which major vein

Answer 3

Branches off the supraorbital vein. continues to enter the orbital septum and become to superior root of the superior ophthalmic.

Question 4

Termination of the supraorbital vein

Answer 4

When it joins with the supratrochlear aka frontal vein to form the angular vein.

Question 5

Which two veins join to form the superior ophthalmic vein

Answer 5

The angular becomes the inferior root (via the angular communication vein) and the supraorbital becomes the superior root (via the communication vein)

Question 6

The supraorbital and supratrochlear (frontal) veins join to form what

Answer 6

When they join, they terminate and form the angular vein. So the angular vein begins at the junction of the supraorbital and supratrochlear near the medial eyelid.

Question 7

Facial vein forms the common facial trunk with the retromandibular and then drains into ___

Answer 7

The internal jugular.

Question 8

Which two veins join to form the retromandubular vein

Answer 8

Superficial temporal vein and the maxillary vein

Question 9

Branches of the superficial temporal vein

Answer 9

Frontal- drains anterior scalp
Parietal- Receives an emissary vein from the superior sagittal sinus.
Transverse Facial
Middle temporal- Exits from under temporalis

Question 10

Where does the superficial temporal vein terminate

Answer 10

In the parotid gland as it joins with the maxillary vein to form the retromandibular vein.

Question 11

Anterior and posterior branches of the retromandibular veins

Answer 11

Inverted Y shape.

Anterior branch joins the facial vein to form the common facial trunk which empties into the internal jugular.

Posterior branch joins the posterior auricular/occipital to form the external jugular vein.

Question 12

Posterior auricular vein has a mastoid emissary vein that connects to which dural venous sinus?

Answer 12

The sigmoid dural venous sinus

Question 13

Which emissary vein connects pterygoid venous plexus and cavernous sinus?

Answer 13

The inconstant emissary vein of vesalius

Question 14

Where is the pterygoid venous plexus located?

Answer 14

Within the infra temporal fossa. Makes up the deep veins of the face.

Question 15

Emissary veins do what

Answer 15

Connect extra cranial (pterygoid plexus, diploic, or scalp veins) to the intracranial drainage system (cavernous sinus).

Can carry infection into the cranium,

Question 16

All dural sinuses are considered to be ___

But not all sinuses in the head are ____

Answer 16

Venous

Veins

Question 17

Dura mater divided into two layers

Answer 17

Outer endosteal - Continuous with periosteum of the scalp.
Inner meningeal - Continuous with epineurium that surrounds the spinal and cranial nerves.

In between the layers is where the dural sinus is located.

Question 18

Greater cerebral vein joins ___ to form the straight sinus

Answer 18

Inferior sagittal sinus

Question 19

Where is the confluence of sinuses located

Answer 19

Located inner to the internal occipital protuberance

Question 20

Straight sinus drains where

Answer 20

Into left or right transverse sinuses

Question 21

The transverse sinuses turn inferiorly to become to

Answer 21

Sigmoid sinuses

Question 22

The sigmoid sinuses exit the skull via the _____ to form the ____ veins.

Answer 22

Exit via the jugular foramen to form the internal jugular veins. The inferior petrosal then drains into the internal jugular vein and not into the sigmoid sinus

Question 23

The inferior petrosal veins drain into what

Answer 23

The internal jugular, not the sigmoid sinuses

Question 24

Venous blood from the cavernous sinus drains where

Answer 24

Into the inferior and superior petrosal into the internal jugular.

Into the pterygoid venous plexus

Question 25

Can a thrombus caused by bacteria be transferred from one part of the cavernous sinus to the other?

Answer 25

Yes, the anterior and posterior portions of the cavernous sinus surrounding the sella turcica connect.

Question 26

The cavernous sinus is a large sac-like venous vessels that are subdivided by thin ____

Answer 26

Trabeculae, which give it a spongy appearance.

Question 27

Where does the cavernous sinus extend from and which nerves and arteries travel though

Answer 27

Extends from the superior orbital fissure to the apex of the petrous temporal bone.

Inlcudes CN III, IV, V1, V2, and VI.

Question 28

Which veins drain into the cavernous sinus

Answer 28

The superior and inferior ophthalmic vein, sphenoparietal sinus and the inferior cerebral veins.
