What are the 8 branches of external carotid artery?

Can we palpate external carotid artery?
Carotid Artery Palpation Have the patient turn slightly toward you to relax the neck muscles, and palpate gently between the sternocleidomastoid (SCM) and the trachea. Do not go above the thyroid cartilage to avoid inadvertently massaging the carotid sinus.
What are the four major branches of the external carotid artery?
- superior thyroid artery.
- ascending pharyngeal artery.
- lingual artery.
- facial artery.
- occipital artery.
- posterior auricular artery.
How can you tell if you have internal and external carotid arteries?
There is a distinct difference in the spectral Doppler pattern between the external and internal carotid artery. The external carotid artery supplies a “high” resistance vascular bed”, while the internal carotid artery supplies the brain which has a low resistance vascular bed.
How can you tell the difference between internal and external carotid arteries?
The examiner should be able to differentiate the internal carotid artery (ICA) from the external carotid artery (ECA). The ICA is located posterior and lateral to the ECA. The ICA is slightly larger than the ECA. The ECA has branches such as the lingual artery, but the ICA does not.
