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