The skin over this area is relatively thin and derives its blood supply from branches of the superficial temporal artery. It is drained chiefly by the superficial temporal vein. The temporal region of the head comprises: 1. Lateral area of the scalp, and 2. The deeper soft tissues overlying the temporal fossa of the cranium, superior to the zygomatic arch. BOUNDARIES OF TEMPORAL FOSSA Anteriorly: frontal and zygomatic bones. Posteriorly and superiorly: temporal lines. Laterally: zygomatic arch. Inferiorly: infratemporal crest. Floor is formed by parts of the following four bones that form the pterion: frontal, temporal, parietal, and greater wing of the sphenoid. The temporalis muscle takes origin from the bony floor and overlying temporal fascia. The temporal fascia forms the roof of the temporal fossa. TEMPORAL FASCIA It is very tough and covers the temporalis, and is attached superiorly to the superior temporal line. Inferiorly, the fascia splits into two layers attaching to the medial and lateral surfaces of the zygomatic arch. The temporal fascia also connects the zygomatic arch superiorly. Masseter is a very powerful muscle and is attached to the inferior border of the zygomatic arch. When it contracts, it exerts a strong downward pull on the zygomatic arch. Temporal fascia offers resistance to this strong pull.

The skin over this area is relatively thin and derives its blood supply from branches of the superficial temporal artery. It is drained chiefly by the superficial temporal vein. The temporal fossa is relatively flat in its superior portion and deepens inferiorly. Its lower border, which we call the infratemporal crest, is marked by several tubercles. The temporal fossa is bridged by the zygomatic arch, whose posterior (larger) root arises from the temporal squama and whose anterior root is formed by the zygomatic process of the zygoma. The temporal muscle is covered laterally by the temporal fascia, upon which course the superficial temporal vessels and the auriculotemporal nerve and its branches; these are adherent to the outer border of the zygomatic arch. From the area of the articular tubercle of the temporomandibular joint, branches of the facial nerve are distributed to the frontal belly of the epicranius muscle and to the orbicularis oculi (temporal branches of the facial nerve).surfaces of the coronoid process. The deep portion of the muscle, which arises partly from the infratemporal plane of the skull, possesses a strong tendon that extends to the retromolar trigone. This tendon is easily palpated from within the oral cavity. Below the temporal fascia is the temporal aponeurosis (deep layer of the temporal fascia), which covers the temporal muscle and is attached to the medial surface of the zygomatic arch. Most of the temporal fibers arise from the temporal plane, and a few (constituting the superficial part) arise from the temporal aponeurosis temporal fossa,temporal fascia,boundaries of temporal fossa,temporalis muscle,temporal region,infratemporal crest,deep temporal artery,deep temporal nerves,middle temporal artery,zygomaticotemporal artery,superior temporal line,inferior temporal line,zygomaticotemporal nerve,lateral sulcus of brain,external auditory meatus,norma lateralis,dr. saqib,middle meningeal artery,pterion,masseter,craniometery,zygomatic arch, Anatomyaxillaknee joint anatomyHip joint anatomymuscles of rotator cuffbrachial plexuspterygopalatine fossafemur bonehip boneheart anatomysurfaces and borders of heartgross anatomyneuro anatomy
