Temporal fossa
Temporal Fossa
The Temporal Fossa (pronounced tem-puh-ruhl foh-suh) is an anatomical term referring to a depression on the side of the skull, above the Arch of the Zygomatic Bone and deep to the Temporal Fascia.
Etymology
The term "Temporal Fossa" is derived from the Latin word 'tempus' meaning time, and the Latin word 'fossa' meaning ditch or trench. The term 'tempus' was used because the temples are where grey hair first appears, indicating the passage of time.
Anatomy
The Temporal Fossa is bounded by several structures:
- Anteriorly: The Posterior Orbital Process of the Frontal Bone
- Superiorly and Posteriorly: The Temporal Line of the Parietal Bone
- Inferiorly: The Zygomatic Arch
The Temporal Fossa contains the Temporalis Muscle, a large, fan-shaped muscle that plays a crucial role in mastication (chewing).
