Sulcus Temporal Middle

The median temporal groove is one of the most important anatomical formations of the human skull. It is located in the thickness of the temporal muscle, surrounding the middle petrous part of the temporal bone. The temporal muscle, temporal fascia and periosteum of the middle ear take part in the structure of the temporal median sulcus.

The groove can be found by the projection of the zygomatic arch. Approximately its upper border falls on the lateral notch of the temporal bone, the lower one runs along the zygomatic arch, and the lateral parts descend along the interpterygoid space. The location of the edge of the sulcal surface somewhat corresponds to the interfascial groove and is interrupted anteriorly at the transition to the mucous membrane of the pharynx. The groove acts as a separate element on the bone relief and is located behind the ridge of the lower jaw joint. It can grow and form a median emphysemogram and connects outward with the ethmoidal notch on the anterior surface of the mastoid process. Emphysema manifests itself as a branched, deep and wide groove passing through the occipital bone. The fossa of the occipital bone has a subtype - trigonoid, which also includes a membrane filled with fat cells. The nape lattice is necessary for accretion to the fibrous capsule of the auricle. That is, through the lattice
