Facial artery
The maxillary molars and premolars, along with their associated gingiva, are primarily supplied by the posterior superior alveolar artery, a branch of the maxillary artery. The middle superior alveolar artery, also a branch of the maxillary artery, may contribute to the blood supply of the maxillary premolars. These arteries ensure adequate vascularization for the teeth and surrounding tissues in the maxillary region.
Maxillary artery, branched from external carotid artery
The main source of arterial blood to the nose is the maxillary artery, which is a branch of the external carotid artery. The maxillary artery gives rise to the sphenopalatine artery, which supplies the nasal cavity and contributes to the rich vascular network in the nasal mucosa. Additionally, the facial artery also provides blood supply to the anterior part of the nose.
The pterygopalatine ganglion receives its blood supply from branches of the maxillary artery, such as the sphenopalatine artery.
The superficial temporal artery supplies most of the head external to the skull. It is a branch of the external carotid artery and itself branches to send blood to the face, forehead and scalp. The other terminal branch of the external carotid, the maxillary artery supplies the deep tissues of the face. The scalp in the back of the head (the occipital area) is supplied by the occipital artery, which is also a branch of the external carotid (but not one of the terminal branches).
