The outer surface of the muscle lies against the inner surface of mandible, from which it is separated by the lateral pterygoid muscle, sphenomandibular ligament, maxillary artery, mandibular nerve and its lingual and inferior alveolar branches. The action of closing the jaw is performed by the upward pull of the temporalis, the masseter, and and the medial pterygoid muscles. Opening of the jaw is brought about partly by the force of gravity, partly by the forward pull of the lateral pterygoid muscles, and partly by the backward and downward pull of muscles we’ll see in a minute, that act by way of the hyoid bone. 2017-07-26 · The frontalis muscle lays directly atop the temporalis muscle, the largest muscle in the head, which raises the mandible and contributes to the action of closing the mouth and chewing. Since it is difficult to isolate the frontalis from the temporalis muscle, it is not possible to palpate it independently from the underlying temporalis. Temporalis muscle hypertrophy (TMH) is a rare entity of masticatory muscle hypertrophy.

Due to its location and frequent use, this The temporal muscle inserts on the medial and lateral aspect of the coronoid process to surround the process. Its lateral ventral extent is the ventral aspect of the masseteric fossa. The muscle contacts the pterygoid muscles on the medial aspect of the coronoid process. The temporalis muscle originates from the temporal fossa – a shallow depression on the lateral aspect of the skull. The muscle is covered by tough fascia which can be harvested surgically and used to repair a perforated tympanic membrane (an operation known as a myringoplasty). Attachments: Originates from the temporal fossa.

The first case of isolated unilateral temporalis hypertrophy was presented in a Caucasian female and was proposed to have an emotionally traumatic aetiology. 4 Biopsy of the temporalis muscle was Maintenance of relatively high EMG activity in anterior temporalis across a wide range of biting behaviors is to be expected in a vertically oriented and rostrally positioned muscle such as this because, compared to the posterior temporalis, superficial masseter and medial pterygoid, it can contribute relatively larger vertical components of force to bites along the postcanine toothrow.
