The internal sinus, often referred to in a medical context, typically pertains to the internal venous sinuses located within the brain, such as the superior sagittal sinus, which drains blood from the brain. These sinuses are channels that collect deoxygenated blood and cerebrospinal fluid, playing a crucial role in the brain's venous drainage system. They are lined by endothelial cells and are essential for maintaining intracranial pressure and overall brain health. In certain contexts, the term may also relate to anatomical cavities or spaces within various organs.
