The scapula is a flat, triangular-shaped bone (colloquially as the "shoulder blade"). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.

The mandible is the largest bone in the human skull. It holds the lower teeth in place, it assists in mastication and forms the lower jawline. The mandible is composed of the body and the ramus and is located inferior to the maxilla. The body is a horizontally curved portion that creates the lower jawline.

The vault of the skull is a region of the neurocranium formed by a process of membranous ossification. It consists of several bones: frontal bone, parietal bone, squamous part of the temporal bone, lamina ascendens of the sphenoid, and interparietal bone

Anatomy of the Skull: Norma basalis ( Anterior part , Middle part ) When the intact skull is viewed from below, the limits of the oral cavity can be seen. Its roof is formed by the hard palate; its walls by the upper and lower teeth embedded in the alveolar processes of the maxillae and the mandible

Pictures primarily visible from front of the skull (norma frontalis) or above the skull (norma verticalis) include: Frontal suture / Metopic suture: between the two frontal bones, prior to the fusion of the two into a single bone. Sagittal suture: along the midline, between parietal bones
