What anatomical feature does the temporalis muscle help in retracting?

• A. Mandible
• B. Maxilla
• C. Temporomandibular joint
• D. Condyle

Answer: (A)

The temporalis muscle plays a critical role in the movement of the mandible, primarily aiding in its retraction. The muscle is situated on the side of the skull, extending from the temporal bone down to the coronoid process of the mandible. When it contracts, it pulls the mandible backward, facilitating actions such as closing the jaw and chewing. The muscle is particularly effective for both elevation and retraction of the mandible, allowing for a range of movements necessary for effective mastication. Understanding this function is key for dental professionals, as it relates to overall jaw mechanics and may impact dental treatments concerning bite alignment and jaw disorders.
