Before its branches, and Continues as?

A 
Starts from Sinus Caroticus where
- Carotis externa and Carotis interna devides from A. Carotis communis.
A.CAROTIS EXTERNA -

    (in CA: LINGUAL A and FACIAL A)
■ Ascending palatine artery
■ Lingual artery
■ Sublingual artery
■ Facial artery
   ● A. Labialis inferior

Q

Common carotid arteries

A

○ Ascend the neck to each side of the trachea accompanied by the
vagosympathetic trunk and caudal laryngeal nerve.

○ Caudal thyroid artery
○ Cranial thyroid artery

■ Cranial laryngeal artery
■ Ascending pharyngeal artery

○ Common carotid then divides into

1: External (head without brain) and
2: Internal carotid (brain),

  1. and the occipital artery

○ Carotid body ( GLOMUS CAROTICUM ) can be found close to this division, a chemoreceptors which responds to changes in blood pressure
