The muscle receives its blood supply from the deep temporal arteries which anastomose with the middle temporal artery.

Deep temporal arteries (anterior and posterior)

The deep temporal arteries, two in number, anterior and posterior, ascend between the Temporalis and the pericranium.

(5) Temporal branches pass through foramina in the great wing of the sphenoid, and anastomose in the temporal fossa with the deep temporal arteries.

The lacrimal artery also give off one or two zygomatic branches, one of which passes through the zygomatico-temporal foramen, to reach the temporal fossa, and anastomoses with the deep temporal arteries; another appears on the cheek through the zygomatico-facial foramen, and anastomoses with the transverse facial.
