Final answer:
The major regions of the skull include the occipital bone forming the occiput, temporal bones corresponding to the temples, the parietal bones forming the parietal regions, and the frontal bone constituting the frontal area. These regions are interconnected by sutures, with more than 100 joints in the skull created by connective tissue.
Step-by-step explanation:
Major Regions of the Human Skull
The human skull is a complex structure that serves to protect the brain and support facial features. It can be divided into the cranial and facial bones. The major parts of the skull relevant to your question include the occiput, temples, parietal, and frontal areas.
- The occiput is the back part of the skull that encloses the brain; it is formed by the occipital bone.
- The temples are located on the sides of the skull, largely corresponding to the temporal bones.
- The parietal region of the skull comprises the upper sides, formed by the two parietal bones.
- The frontal area is the front part of the skull, made up of the frontal bone.
These areas are connected by sutures — the sagittal suture joins the parietal bones, the coronal suture connects the parietal bones to the frontal bone, the lambdoid suture joins the parietal bones to the occipital bone, and the squamous suture joins the parietal bones to the temporal bones. These sutures are filled with dense, fibrous connective tissue that unites the bones. The skull, overall, consists of connective tissue joints, allowing for the firm connection of its various parts.
