Sagittarius Sinus Inferior

Ultrasound examination (ultrasound) of soft tissues can be used to diagnose various diseases and pathologies in the head and neck area. Among them are the sagittal and sigmoid sinuses. In this article we will look at the Sagittarius Inferior Sinus.

There may be several sagittal sinuses found in humans, but they all form a common structure - the oval foramen, which connects the posterior cranial fossa with the subarachnoid space. The sagittal inferior belongs to one of these sinuses. There is another type of sinuses in the head - stony.

An important aspect to understand the inferior sagittal sinus is that it connects to the petrous reticulum both above and below the superior sagittal sinus. Like other types of sinuses, sagittal sinuses are vessels with a valve and belong to the venous system. Inside the lower network there is a cavernous cavity in which the lymph nodes are located. Also at the lower ends of the sinuses there are one or more neurovascular bundles.

The inferior sagittal sinuses may vary in shape and size. The closer to the base of the skull they are, the more bends and channels formed by this area. To determine the shape and size of the inferior arrow sinus, an experienced ultrasound physician is needed. He can do research and suggest additional options for
