Description[edit | edit source]
The temporalis muscle is one of the four primary muscles of mastication. It is a fan-shaped muscle with anterior fibres that have a vertical orientation, mid fibres have an oblique orientation, and posterior fibres have a more of horizontal orientation. [1]
Origin[edit | edit source]
Temporal bone, specifically the floor of the temporal fossa
Insertion[edit | edit source]
Coronoid process of the mandible
Nerve[edit | edit source]
- Central part: deep temporal nerves of the mandibular nerve
- Anterior part: branches of the buccal nerve
- Posterior part: branches of the masseteric nerve
Artery[edit | edit source]
Function[edit | edit source]
- Anterior fibres: Elevates mandible
- Posterior fibres: Retracts the mandible
Clinical relevance[edit | edit source]
Temporalis is used for:[2]
- Direct temporalis tendon injections
- As a landmark for inferior alveolar nerve block anesthesia, third molar extraction, and determining posterior denture flange
- Temporalis tendon transfers in plastic surgery
