Ethmoid Bone, Cribriform Plate

The ethmoid bone is a bone of the brain part of the skull, which is part of the anterior section of the base of the skull and mainly the facial skull, participating in the formation of the walls of the orbits and the nasal cavity. The cribriform plate of the ethmoid bone is pierced by many small holes through which the olfactory nerves pass. This plate separates the cranial cavity from the nasal cavity.

The ethmoid bone consists of a thin anterior and posterior plate, between which there is spongy bone. The anterior plate forms the cribriform plate, through the openings of which the olfactory nerves pass from the cranial cavity to the nasal cavity.

The ethmoid bone plays an important role in the formation of the bony walls of the nasal cavity, orbits, and the base of the skull. It is closely connected with the frontal, sphenoid and maxillary bones.

The mogul bone of the skull is one of the most important bones in the human body. It is part of the anterior part of the skull and is involved in the formation of the walls of the orbit and nasal cavity, as well as in the formation of the facial skull.

One of the parts of the mogul section is the ethmoid bone, which consists of several plates. One of them, the cribriform plate or cribriform plate, is pierced by many small holes through which the olfactory nerve passes.

The cribriform plate is an important part of the cranium. It participates in the formation of the facial skull and the walls of the orbit. In addition, it ensures the passage of the olfactory nerve through the skull.

Overall, the cranial region of the skull is very important to the human body as it provides many functions including smell, hearing, vision and speech.

The ethmoid bone is an element of the cranium of humans and other primates. This bone borders the facial skull and the pons. It is also called the supraorbital bone.

The ethmoid septum bone consists of several parts. The main part of the latticework is the superior ethmoid bone. It is located in the facial skull. Its membrane contains many nerve endings and blood vessels. In the center of this part there is a fixed crepidus - a strong bone tooth. The crepidus is not part of the upper lattice structure.

The second part is the lower grid plate
