What is the main artery that supplies the face?

The facial artery is the chief artery of the face. It arises from the external carotid artery and supplies most facial structures, including the lips and nose.

Where does the facial artery originate from?

The facial artery originates from the external carotid artery at the level of the greater cornu of the hyoid bone in the neck.

What are the named branches of the facial artery in the face?

In the face, the facial artery gives off the inferior labial artery to the lower lip, superior labial artery to the upper lip, lateral nasal artery to the nose, and small muscular branches.

Why is the facial artery tortuous in its course?

The facial artery has a tortuous path to accommodate facial movements, such as expressions and chewing, without being stretched or damaged.

What are the clinical implications of the facial artery's anastomoses?

The facial artery forms important anastomoses with the contralateral labial arteries across the midline, causing profuse bleeding if cut, and with the ophthalmic artery at the medial eye angle, connecting external and internal carotid systems.

Where can you palpate the pulse of the facial artery?

The facial artery pulse is palpable at the lower border of the mandible near the anteroinferior angle of the masseter muscle and 1.25 cm lateral to the angle of the mouth.

What other arteries supply the face besides the facial artery?

Other arteries include the transverse facial artery, a branch of the superficial temporal artery, and small arteries accompanying cutaneous nerves, such as the infraorbital, buccal, and mental arteries from the maxillary artery.

What is the significance of the facial artery's termination?

The facial artery terminates as the angular artery by anastomosing with the dorsal nasal branch of the ophthalmic artery. This creates a connection between the external and internal carotid circulations.
