Definition

Sinus sigmoideus is the Latin term for the sigmoid sinus, an S-shaped venous channel inside the skull. It is responsible for draining blood from the brain, primarily from the transverse sinus. Imagine it as a major drainage pathway for the brain. It connects to the internal jugular vein, carrying blood away from the head and neck. Its structure is important for maintaining proper blood flow. Problems can affect brain drainage, increasing intracranial pressure.

Etymology

"Sinus" in Latin means 'bay' or 'curve,' referring to its channel-like structure. "Sigmoideus" describes its S-shape, similar to the Greek letter sigma. This term underscores its distinctive curvature within the skull. It helps to precisely locate this sinus within the cranium.
