Zygomatic: buccal, mandibular, cervical, when gland is infected it interrupts and messes with the muscles that the branch is affected with if the swelling progresses for a long time it will do permanent damage to the facial nerve. When damaged, your face melts" on that side which is called bell"s. Palsy you lose the ability of these muscles to uplift the face on that side. Muscles of mastication aka chewing deep fascia over temporalis: on the temporal bone, moves under zygomatic arch and is attached onto the mandible if you move your jaw up and down you feel this muscle bulging out. Intrinsic muscles of tongue important to speech & chewing but not prime movers of the jaw.
