  2. Depressor anguli oris muscle - Wikipedia

    en.wikipedia.org/wiki/Depressor_anguli_oris_muscle

    The depressor anguli oris arises from the lateral surface of the mandible. [1] Its fibers then converge. It is inserted by a narrow fasciculus into the angle of the mouth. [1] At its origin, it is continuous with the platysma muscle, and at its insertion with the orbicularis oris muscle and risorius muscle.

    It passes anterior-ward deep to the platysma and depressor anguli oris muscles. It provides motor innervation to muscles of the lower lip and chin: the depressor labii inferioris muscle, depressor anguli oris muscle, and mentalis muscle. [1] It communicates with the mental branch of the inferior alveolar nerve. [citation needed]

    en.wikipedia.org/wiki/Temporomandibular_joint...

    No adverse events regarding exercise therapy and manual therapy have been reported. [26] There have been positive results when using postural exercises and jaw exercises to treat both myogenous (muscular) and arthrogenous (articular) TMJ dysfunction. MT alone or in combination with exercises shows promising effects. [26]

  5. Muscles of mastication - Wikipedia

    en.wikipedia.org/wiki/Muscles_of_mastication

    The four classical muscles of mastication elevate the mandible (closing the jaw) and move it forward/backward and laterally, facilitating biting and chewing. Other muscles are responsible for opening the jaw, namely the geniohyoid , mylohyoid , and digastric muscles (the lateral pterygoid may play a role).

  6. Depressor labii inferioris muscle - Wikipedia

    en.wikipedia.org/wiki/Depressor_labii_inferioris...

    The depressor labii inferioris muscle helps to depress and everts the lower lip. [1] It is the most important of the muscles of the lower lip for this function. [1] It is an antagonist of the orbicularis oris muscle. [1] It is needed to expose the mandibular (lower) teeth during smiling. [1]

  7. Temporomandibular joint - Wikipedia

    en.wikipedia.org/wiki/Temporomandibular_joint

    These four muscles, all innervated by V 3, or the mandibular division of the trigeminal nerve, work in different groups to move the mandible in different directions. Contraction of the lateral pterygoid acts to pull the disc and condyle forward within the glenoid fossa and down the articular eminence; thus, the action of this muscle serves to ...
