On the lateral surface of the cranium, we can detect a small space — the temporal fossa (fossa temporalis).

Temporal fossa (fossa temporalis)

From the bottom, it is separated from the infratemporal fossa by the infratemporal crest (crista infratemporalis) of the great wing of the sphenoidal bone.

The infratemporal fossa has several walls.

The anterior wall is formed by:

  • temporal surface of the zygomatic bone (facies temporalis ossis zygomatici)

    Temporal surface of the zygomatic bone (facies temporalis ossis zygomatici)
    Temporal surface of the zygomatic bone (facies temporalis ossis zygomatici)
  • zygomatic process of the frontal bone (processus zygomaticus ossis frontalis)

    Zygomatic process of the frontal bone (processus zygomaticus ossis frontalis)
    Zygomatic process of the frontal bone (processus zygomaticus ossis frontalis)

    The medial wall is formed by:

  • temporal surface of the greater wing of the sphenoidal bone (facies temporalis alae majores ossis sphenoidalis)

    Temporal surface of the greater wing of the sphenoidal bone (facies temporalis alae majores ossis sphenoidalis)
    Temporal surface of the greater wing of the sphenoidal bone (facies temporalis alae majores ossis sphenoidalis)
  • squamous part of the temporal bone (squama ossis temporalis)

    Squamous part of the temporal bone (squama ossis temporalis)
    Squamous part of the temporal bone (squama ossis temporalis)
  • parietal bone (os parietale)

The lateral wall is formed by the zygomatic arch (arcus zygomaticus).

The temporal fossa contains the temporal muscle, the deep and superficial temporal arteries, the deep and superficial temporal veins, the auriculotemporal nerve, the temporal nerves, and branches of the parotid plexus of the facial nerve.

The temporal fossa is connected to the orbit through the zygomaticotemporal foramen (foramen zygomaticotemporale).
