Study Notes

Great Vessels of the Head and Neck

Common Carotid Artery

Origin: Right common carotid artery is a terminal branch of the brachiocephalic artery, behind the sternoclavicular joint; Left common carotid artery arises in the thorax from the arch of the aorta.
Branches:
- Eight branches that can be grouped into:
  - Three anterior branches
  - Two posterior branches
  - One medial branch: ascending pharyngeal
  - Two terminal branches: maxillary and superficial temporal

Lingual Artery

Origin: Arises opposite the tip of the greater cornu of the hyoid bone.
Course: Divided into three parts by the hyoglossus muscle.
Branches:
- Suprahyoid artery: arises from the first part and passes along the upper border of the hyoid bone.
- Dorsal lingual arteries: arise from the second part and consist of 3 or 4 branches to supply the tongue, tonsil, and soft palate.
- Sublingual artery: arises from the third part and supplies the sublingual gland.

Facial Artery

Branches in the face:
- Angular
- Lateral nasal
- Artery to cheeks
- Superior labial
- Ascending palatine
- Inferior labial
Cervical branches:
- Tonsilar
- Glandular
- Summental

Subclavian Artery

Origin:
- Right side: terminal branch of the brachiocephalic artery, behind the sternoclavicular joint.
- Left side: arises in the thorax from the arch of the aorta and ascends to enter the neck behind the sternoclavicular joint.
Parts:
- First part: medial to the scalenus anterior.
- Second part: lies behind the scalenus anterior.
- Third part: lateral to the scalenus anterior.
Branches:
- First part: gives 3 branches:
  - Vertebral artery
  - Thyrocervical trunk
  - Internal thoracic artery
- Second part: gives one branch: costocervical trunk.
- Third part: no branches.

Vertebral Artery

Origin: From the first part of the subclavian artery.
Course: Enters the cranial cavity and supplies the spinal cord and brain.
