Opisthocranion

Opistocranium is an anatomical term that refers to the area at the back of the skull. It includes the occipital bone, the occipital point and the foramen magnum. Opistocranium is an important anatomical element, as it plays an important role in maintaining balance and coordination of human movements.

Opistocranium consists of two main parts - the occipital bone and the occipital point. The occipital bone is the part of the skull that is located at the back of the head and supports the occipital region. It is shaped like a triangle and is made up of several bones, including the parietal, occipital, and sphenoid bones.

The occipital point is the point on the back of the head where the skull connects to the spine. It is located at the junction of the occipital bone and the skull. The foramen magnum, which is located between the occipital point and the occipital bone, provides the connection between the skull and the spine.

The functions of opistocrania include supporting the head, controlling balance, and coordinating movements. The skull and occiput play an important role in these functions as they provide stability and support to the brain and other organs.

In addition, the opistocranium can be damaged by head injuries or other diseases. This can lead to problems with balance, coordination and other problems. Therefore, it is important to know the anatomy and functions of opistocrania to understand brain health and function.

Opistocranion is a protrusion of the posterior edge of the basil in the form of one or two vertical arcs or a transverse line, forming the upper part of the human skeleton. In humans and higher apes, it is located symmetrically on the lateral parts of the back of the skull along the midline. Opisthokraion is also characteristic of bats. Birds of prey have a homologous structure - a feather tubercle.

Opistocrannon is the posterior point of the skull. It is one of the largest and strongest points on the human skull; it is also called the occipital point of the skull. It is located in the upper back part of the skull, not close to its front surface, but slightly moved away from it.

It has the shape of a triangle, the bases of which are on the back surface of the occiput, and the apex is on the tubercle of the sphenoid bone behind the external auditory canal. Also in front, connecting with the anterior arch and the edge of the squama of the temporal bone, the opistocrannon forms the cranial vault. The upper fossa of the pyramid, on which the levator palpebrae superioris muscle also lies, is attached to the bottom of the opistocrannon. On the side, the hyoid bone is inserted into the mandibular triangle formed by the body of this bone and the branch of the lower jaw. The attachment point of the occipital artery and vein is also located on the opisthocranium.

The ventral surface has a transverse ridge, along the edge of which there are holes for attaching the dura mater. The outer surface smoothly passes into the posterior superior plane of the occipital bone.
