Skull Ii (Skull)

Skull II (Skull): structure and functions

Skull II (Skull) is the head skeleton, which consists of 29 bones. It forms the basis of the brain and the facial part of the skull. Skull II consists of two main parts: the brain region and the facial region.

The brain section of the skull consists of eight bones: frontal, parietal (two), occipital and temporal (two). These bones form the roof of the skull, which is called calvaria. In addition, the sphenoid and ethmoid bones are located in the brain part of the skull. All these bones are strongly connected to each other and do not allow any movement.

The bones of the skull roof are flat and consist of two thin plates of compact bone substance, between which there is a spongy substance - diplot. The depth of the diploe depends on the location of the bone and can reach several centimeters.

The facial part of the skull consists of 15 bones, including the paired nasal, lacrimal, inferior turbinates, maxillae, zygomatic and palatine bones, as well as the unpaired vomer, mandible and hyoid bone. All the bones of the facial part of the skull are strongly connected to each other, with the exception of the lower jaw and hyoid bone, which can move.

The skull has a number of important structures, such as the orbit, nasal cavity, temporal, infratemporal and pterygopalatine fossa, as well as the bony palate. At the base of the skull is the foramen magnum, through which the spinal cord passes.

Skull II has several important functions. First, it protects the brain. Second, skull II provides support and strength for the muscles and ligaments that control movement of the head and neck. In addition, skull II plays an important role in the process of respiration and digestion.

In conclusion, skull II is one of the most important parts of the human skeleton. It provides protection to the brain, supports the muscles and ligaments that control movement of the head and neck, and plays a role in breathing and digestion.

Skull II (Skull), also known as the skeleton of the head, consists of 29 bones and is an important organ of the human body. It consists of two sections: the brain and the facial. The brain section consists of eight bones that form the roof of the skull, and the facial part includes 15 paired and unpaired bones.

The brain section is formed by the frontal, parietal, occipital and temporal bones, as well as the sphenoid and ethmoid bones. The roof of the skull consists of flat bones, which are formed by two thin plates of compact bone substance. Between them is a spongy substance called diploe.

The facial part of the skull consists of paired and unpaired bones, including the nasal, lacrimal, inferior and superior turbinates, jaws, cheekbones, palatines and vomer. The mandibles and hyoid bones are the only movable bones of the skull.

All bones of the skull are connected to each other immovably, with the exception of the lower jaw and hyoid bones, which can move during chewing and speech. The skull is an important structural element of the human body and provides protection to the brain and organs located within it.

The skull is the basis of the bone structure of the human body and is the skeleton of the head, which consists of 29 individual bones. It is the seat of the brain and includes various important formations, such as the orbit, temporal and infratemporal fossa, and others. It is important to remember that each of these skull bones forms a unique anatomical aspect, and incorrect dissection of this complex mechanism can lead to serious medical errors and even death.

In cross-section, the skull appears to be deeper than previously thought. On top of the frontal bone is a section called the "rahimen", which is made up of four lamellar bones. Under the rachimen there is a section with four bony ridges called "diosphenol", the surface of which is lined with dura mater. At the back end of the head under the rakhi
