Create a 6 pages page paper that discusses major anatomical divisions of the human skull. Thus, the spinal cord moves via the large opening, making it to have a connection with the brain via the medulla oblongata. Laterally to the foramen magnum, hypoglossal canals, which establish pathways for hypoglossal nerves, exist. Jugular foramina live at the end of the temporal bones. These canals and foramen facilitate in hosting nerves and blood vessels in the skull.

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. The skull has 14 facial bones and eight cranial bones. These bones facilitate the provision of protection to the brain and support nerves and organs, such as smell, vision, equilibrium, hearing, and taste (Sharifi et al., 2013). Further, the bonus offers an attachment for muscles, which aid in the control of chewing and facial expressions and allows the head’s movement.

Embryonic tissue origin and bone formation.

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. The skull has a total of 22 bones. Immobile joints regarded as sutures unite the separate bones of the cranial part of the head. The sutural ligaments hold these joints. The skull is linked to the mandible by the mobile synovial joint, which is the temporomandibular joint. Diploe is a spongy bone layer, which separates the internal and external tables of skull bones (Hitoshi et al., 2013). The internal table is brittle and thinner than the external table, but the periosteum covers the bones’ inner and outer surfaces.

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. The bones of the skull have two divisions, which are cranium bones and facial bones. Cranium has the following bones frontal bone (1), ethmoid bone (1), sphenoid bone (1), occipital bone (1), parietal bones (2), and temporal bones (2) (Sheikh et al., 2014). Such indicates that the skull only has two bones, which are paired. Face bones include mandible (1), vomer (1), zygomatic bones (2), maxillae (2), nasal bones (2), inferior conchae (2), palatine bones (2), and lacrimal bones (2). Thus, the face has only two bones, which are not paired.

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. The frontal bone is responsible for forming the forehead, which curves and bends downwards by having upper orbit margins. It articulates with nasal and maxillae bones medially and with the zygomatic bone laterally. Key features of the frontal bone are the supraorbital notches and super ciliary arches, and frontal air sinuses. The spaces create room for nose communication, as well as voice resonation.
