The temporal fossa is a fossa (shallow depression) on the side of the skull bounded by the temporal lines above, and the zygomatic arch below. Its floor is formed by the outer surfaces of four bones of the skull. The fossa is filled by the temporalis muscle.
Anatomy
[edit | edit source]Boundaries
[edit | edit source]- Medial/floor: frontal bone, parietal bone, (squamous part of) temporal bone, and sphenoid bone. The floor of the fossa features the pterion (the junction of these four bones).[1]: 357
- Lateral/roof: temporal fascia.[1]: 357
- Anterior: (posterior surface of) the frontal process of zygomatic bone,[citation needed] (the posterior surface of[citation needed]) the zygomatic process of frontal bone, and the maxilla.[1]: 357
- Superior: Pair of temporal lines (superior and inferior temporal lines) that arch across the skull from the zygomatic process of the frontal bone to the supramastoid crest of the temporal bone[citation needed]
- Inferior: zygomatic arch laterally and by the infratemporal crest of the greater wing of the sphenoid medially.[citation needed]
Contents

- Deep temporal arteries[citation needed]
- Deep temporal nerves[citation needed]
- Zygomaticotemporal nerve[citation needed]
Relations
[edit | edit source]Deep to the zygomatic arch, the temporal fossa is inferiorly continuous with the (lateral part of) the infratemporal fossa.[1]: 357
