Blood Supply of the Facial Muscles

00:00 Now we'll finish up by looking at the blood supply. When we look at the occipital frontal muscle, frontalis muscle, this muscle is going to be supplied by branches of the superficial temporal, ophthalmic, posterior auricular, and occipital arteries. The orbicularis oculi is arterially supplied by branches of the facial, superficial temporal, maxillary, and ophthalmic arteries. The corrugator supercilii is arterially fed by branches of the superficial temporal and ophthalmic arteries. The procerus is supplied by branches that come from the facial artery. Levator labii superioris alaeque nasi is fed by branches from the facial artery and infraorbital branch of the maxillary artery and the same can be said for the levator labii superioris and then the last muscle here is the zygomaticus major muscle. This is supplied by the superior labial branch of the facial artery nasialis branches from facial artery and from infraorbital branch of the maxillary artery. Buccinator branches from the facial artery and the buccal branch of the maxillary artery, levator angulii oris, superior labial branch of the facial artery and the infraorbital branch of the maxillary. The risorius is arterially fed by the superior labial branch of your facial artery. Orbicularis oris superior and inferior labial branches of the facial artery. The mental, the infraorbital branches of the maxillary artery and the transverse facial branch of the superficial temporal artery and the last muscle in this table is depressor labii inferioris. The blood supply here is from the inferior labial branch of the facial artery and the mental branch of the maxillary. And the last table, we have depressor angulii oris. Its supply is from the inferior labial branch of the facial artery and the mental branch of the maxillary. The mentalis is fed by the inferior labial branch of the facial artery and the mental branch of the maxillary as well.

02:24 Risorius is the superior labial branch of the facial auricularis muscles, posterior auricular artery temporalis, deep and superficial temporal branches from the maxillary artery.

02:38 And then both pterygoids, lateral pterygoid and medial pterygoid they are supplied by the the pterygoid branches from the maxillary artery.
