Anatomy - The Face

Question 1

What two branches are key for facial blood supply?

Answer 1

1. Facial
2. Maxillary

Inferior labial - lower lip

Transverse Facial - Parotid gland and duct

Angular - Lateral nose

Question 4

What are some key branches of the maxillary artery?

Answer 4

Superior alveolar - Upper teeth

Inferior alveolar - Lower teeth

Mental - via mental foramen to do chin

Middle meningeal - Dura

Question 5

What foramen do branches of the maxillary artery pass through?

Answer 5

Mental

Infraorbital

Question 6

What does the mental artery anastamose with?

Answer 6

Question 7

What are the key veins in the venous drainage of the face?

Answer 7

Facial Vein

Angular vein

Question 8

What drains in to the angular vein?

What does the angular vein become?

Answer 8

Supraorbital vein

Supratrochlear vein

It becomes the facial vein

Question 9

What else drains into the facial vein?

Answer 9

Mental Vein

Submental Vein

Question 10

What is the superficial layer or muscle below the face?

Answer 10
