Answer 6

Left side
- Starts directly at the aorta and travels up the left side of the head

- Internal- supplies blood to everything a little above the mouth
- eyes, forehead, lachrymal gland

Question 8

External carotid artery

Answer 8

8 branches, 4 categories
- Anterior
- Superior thyroid
- Lingual
- Facial
- Posterior
- Occipital
- Posterior auricular
- Medial
- Ascending pharyngeal
- Terminal
- Maxillary
- Superficial temporal

Question 9

Superior thyroid artery

Answer 9

Supplies:
-larynx, thyroid, infra hyoid, and SCM

Question 10

Lingual artery

Answer 10

Supplies the tongue and sublingual structures

-below the tongue

Question 11

Facial artery

Answer 11

Supplies tonsils, palate, submandibular, and salivary glands

Question 12

Question 13

Posterior auricular artery

Answer 13

• travels up through and behind the ear
• supplies the internal ear by its auricular branch and they mastoid process by the stylomastoid artery

Question 14

Answer 14

• supplies blood to the pharyngeal wall
• Can’t see from a lateral view

Question 15

Superficial Temporal artery

Answer 15

• Supplies blood to the temporal region
• Visible under the skin

Question 16

Maxillary artery

Answer 16

• Inferior alveolar branch
  
  • Below the alveolar bone, supplies blood to mandibular teeth
• Posterior superior alveolar artery
  
  • Supplies blood to the maxillary teeth

Question 17

Internal Jugular vein

Answer 17

Runs next to the carotid

• drains the brain and most of the other structures of the head and neck

Question 18

External jugular vein

Answer 18

• only drains a small part of the extra cranial structures

Question 19

Cavernous sinus

Answer 19

On the lateral surfaces of the spenoid bone

involved in the spread of dental infection

Question 20

Pterygoid Plexus of veins

Answer 20

Protects the maxillary artery from being compressed
