Flashcards in 2nd QUARTER- ANATOMY 2 Exam 4 Deck (15):
1

Feed the left/right anterior (front) portion of the cerebrum or brain tissue.

Left/Right anterior cerebral artery

2

Does not feed any specific part of brain tissue. Its purpose is to communicate or join the right/left internal carotid artery to the right/left posterior cerebral artery.

Right/Left posterior communicating artery

3

feed the right/left posterior portion of cerebrum or brain tissue.

Right/Left posterior cerebral artery

4

The only single/unpaired artery. Does not feed any specific part of brain tissue. Its purpose is to communicate or join the left and right anterior cerebral artery to each other. Its entire length is involved in making up the circle. Without it, we wouldn't have a complete ring.

Anterior communicating artery (NAPPY HEAD LONELY DUDE!!)

5

the union or joining together of blood vessels

Anastomosis

6

List the arteries involved in making up the Circle of Willis

Right & Left Internal Carotid Arteries
Right & Left Posterior Communicating Arteries
Right & Left Posterior Cerebral Arteries
Right & Left Anterior Cerebral Arteries

5 branches of Facial Side (from most lateral to most superiorly)

1. Superior thyroid artery - the first branch of the external carotid artery to rise on the facial side. Feeds the superior portion of the thyroid gland.

2. Lingual artery - the second branch of the external carotid artery on the facial side. Feeds the tongue.

3. Facial artery - the third branch of the external carotid artery on the facial side. For testing purposes, the facial artery is the most important branch off the external carotid artery during embalming because it feeds the face - the cheeks, lips, mouth, nose, and eyelids. It passes behind the mandible or lower jaw.

4. Maxillary artery - the fourth branch of the external carotid artery on the facial side. Feeds the maxilla or upper jaw, the upper teeth, and the majority of the muscles of mastication.

5. Superficial temporal artery - the fifth branch of the external carotid artery on the facial side and most superior artery that feeds the forehead region. The forehead region - the anterior 1/3 of a person’s scalp that is fed by the superficial temporal artery.

3 branches of Auricular Side

Hint:

Positions

1. Ascending pharyngeal artery - the first branch to rise off the external carotid artery on the auricular side. Feeds the pharynx (throat) and the soft palate (roof of the mouth that consists of soft tissue).

2. Occipital Artery - the second branch off the external carotid artery on the auricular side. Feeds the occipital region (back of the head). The occipital region- The posterior 1/3 of a person’s scalp is fed by the occipital artery.

3. Posterior auricular artery - the third branch off the external carotid artery on the auricular side. This is the most superior branch on the auricular side. It travels behind the ear. Feeds the middle (lateral) 1/3 of the scalp.

9

(deep brachial artery) branch off the brachial artery that feeds the triceps brachii muscles.

Profunda branchii

10

A circle of arteries that feed the cerebrum (the largest part of brain tissue).

Circle of Willis

11

The Circle of Willis is also called...

Cerebroarterial Circle

12

the point on either side of the neck, at which each common carotid artery terminates by splitting into an

(1) Internal carotid artery (feeds inside the skull)

(2) External carotid artery (feeds the outside of the skull)

Carotid sinus

13

It is a continuation of the Right Common Carotid Artery. The largest sized artery that bring blood to base of the brain.

Right/Left internal carotid artery

14

branch off subclavian artery off the left/right. Which goes superiorly

Left/right vertebral artery

15

an unpaired or single artery formed by the union of the left and right vertebral arteries. It is a contributing artery of the circle of Willis.

Basilar artery
