Soustye Occipitosinusnoe

The occipitosinus anastomosis (anastomosis occipito-sinualis) is an anatomical formation that connects the posterior cranial fossa with the lateral surface of the body of the sphenoid bone. It plays an important role in human anatomy and physiology, as it provides a connection between these two structures.

The occipitosinus anastomosis is one of three anastomoses in the skull. The other two anastomoses are the greater and lesser occipitotemporal anastomosis and the greater occipital-mastoid anastomosis.

Anatomically, the anastomosis is a connecting canal that connects the posterior cranial fossa (the opening where the cerebellum is located) with the lateral surface of the sphenoid sinus (the cavity that is located in the body of the sphenoid bone).

The functional significance of the occipitosinus anastomosis is that it ensures the exchange of substances between the blood circulating in the posterior cranial fossa and the air in the sphenoid sinus. This allows you to maintain homeostasis in the cranial cavity and ensures normal functioning of the brain.

In addition, the occipitosinus anastomosis can be subject to various pathological changes, such as inflammatory processes, tumors or trauma. In such conditions, the normal functioning of the anastomosis may be disrupted, which can lead to various diseases, for example, poor circulation in the brain or the development of sinusitis.

Thus, the occipitosinus anastomosis plays an important role in the anatomical and functional structure of the skull and can be subject to various pathological processes that can affect human health and well-being.
