Temporal muscle enter spastic paralysis, this clenching in extreme cases can lead to a rupture specifically on the myotendinous insertion at the coronoid process of the mandible. Temporal muscle The temporal muscle, also known as the temporalis, is one of the muscles of mastication. It is a broad, fan-shaped muscle on each side of the head that fills the temporal fossa, superior to the zygomatic arch so it covers much of the temporal bone. In humans, it arises from the temporal fossa and the deep part of temporal fascia. It passes medial to the zygomatic arch and forms a tendon which inserts
Fourth metatarsal bone on the lateral side a single facet, for articulation with the fifth metatarsal. The head or anterior extremity articulates with the fourth proximal phalanx, the first bone in the fourth toe. The third and fourth dorsal interossei muscles attaches to the fourth metatarsal bone. The third dorsal interossei from the medial side of the bone and the fourth dorsal interossei from the lateral side. The function of the muscle is to spread the toes. The second Plantar interossei muscle originates from the medial side of the base and shaft of the fourth metatarsal. The function of the muscle is to
