2 Circulation of head and neck
(1) Subclavian artery (2) common carotid artery 頸根--- vertebral artery thyrocervical trunk costocervical trunk (subclavian a.的分支, 位在前斜角肌內側及後側) 頸部及頭部---common carotid artery 腦---vertebral a. and internal carotid a.

3 Thyrocervical trunk 頸根---thyrocervical trunk (前斜角肌內側)
有4個分支, 2支往上, 2支往後 inferior thyroid . ascending cervical artery: 沿前斜角表面上行, 與膈神經伴行 transverse cervical artery: 行至提肩胛肌後分為淺支及深支 suprascapular artery 頸根--Vertebral artery Thyrocervical trunk Vertebral a.

4 Vertebral artery 鎖骨下動脈的分支, 位在甲狀頸幹的深層 2. 行走於C6-C1的橫突孔
Thyrocervical trunk Costocervical trunk

5 Common carotid artery 總頸動脈一直到甲狀軟骨上緣 才分為頸外動脈頸及頸內動脈 2. 頸內動脈在頸部無分支,
一直至顱內才會分支 3. 頸外動脈有8大分支 頸內動脈 頸外動脈

6 External carotid artery
1. 頸外動脈可分為8大分支 (1) Superior thyroid artery (2) Ascending pharyngeal artery (3) Lingual artery (4) Facial artery : superior and inferior labial artery and angular a. (5) Occipital artery (6) Maxillary artery (7) Superficial temporal artery: transverse facial artery (8) Posterior auricular artery 2. 記憶法: 2—3—3法則 顏面動脈

7 External carotid artery
記憶法: 2—3—3法則 分叉處2支: superior thyroid a. ascending pharyngeal a. 舌骨處3支: facial a. lingual a. occipital a. 終末3支: maxillary a, superior temporal a. posterior auricular a.

8 Facial artery : 走在嚼肌的前緣 分支: 1. superior labial artery
2. inferior labial artery 3. angular a. 3 1 2
