The artery that supplies the chin and jaw region of the head with blood is the facial artery which is a branch of the external carotid artery. All blood from the head arises from the common carotid artery wherein it is divided to internal carotid artery (major blood supply of the brain along with the basilar artery on the posterior side) and external carotid artery (major blood supply of the head other than the brain).

The external carotid artery has 8 major branches (from inferior to superior): (1) superior thyroid artery, (2) ascending pharyngeal artery, (3) lingual artery, (4) facial artery, (5) occipital artery, (6) posterior auricular artery, (7) maxillary artery, and (6) superficial temporal artery.

Attached is a simplified photo of the branches of the external carotid artery.

Why would a third-degree burn be less painful than a first- or second-degree burn involving the same body area?

Irina18 [472]

A third-degree burn would be less painful than a first- or second-degree burn involving the same body area because of the destruction of underlying pain receptors.
Nerve endings are destroyed in third-degree burns, which means that a person can no longer feel pain in that particular spot on the body. Third-degree burns are the most severe ones and cannot be treated easily - usually skin grafting or synthetic skin has to be used to replace the burnt skin.
