The document discusses the major arteries of the neck including the common carotid artery, internal carotid artery, external carotid artery, vertebral artery, and brachiocephalic artery. The common carotid artery divides into the internal and external carotid arteries. The internal carotid artery supplies the brain, while the external carotid artery supplies the face and neck. The vertebral arteries originate from the subclavian arteries and supply the spinal cord, brainstem, cerebellum, and back of the brain. The brachiocephalic artery is the first branch of the aortic arch and divides into the right common carotid and right subclavian arteries.

2. Arteries of Neck

4. Content
 Common carotid artery
 Internal carotid artery
 External carotid artery
 Vertebral artery
 Brachiocephalic artery

5. Common carotid artery
In anatomy, the left and right common carotid arteries
they divide in the neck to form the external
and internal carotid arteries.
 The common carotid arteries are present
 on the left and right sides of the body.
 These arteries originate from different arteries,

7. Internal carotid artery
 The internal carotid artery is a major paired artery
 They arise from the common carotid arteries
 where these bifurcate into the internal and
 external carotid arteries at cervical vertebral level 3 or 4;
 the internal carotid artery supplies the brain,

10. External carotid artery
 The external carotid artery is a major artery of the head and neck. It arises from
the common carotid artery when it splits into the external and internal carotid
artery. It supplies blood to the face and neck.

The external carotid artery begins at the upper border of thyroid cartilage,
and curves, passing forward and upward, and then inclining backward to the
space behind the neck of the mandible, where it divides into the superficial
temporal and maxillary artery within the parotid gland.

12. Vertebral artery
 The vertebral arteries are major arteries of the neck.
 Typically, the vertebral arteries originate from the subclavian arteries.
 the vertebral arteries provide supply blood to the upper
 spinal cord, brainstem, cerebellum, and posterior part of brain.

15. Brachiocephalic artery
 The brachiocephalic artery is an artery of the
 mediastinum that supplies blood to the right arm
 and the head and neck.
 It is the first branch of the aortic arch,
 and soon after it emerges, the brachiocephalic artery
 divides into the right common carotid artery
 and the right subclavian artery.
