SINUS CIRCULARIS Meaning and Definition

1. Sinus circularis, also known as the circular sinus or torcular Herophili, is a term used in anatomy to refer to a specific region of the brain. It is a circular-shaped structure located at the confluence of several large venous sinuses in the brain.

   The circular sinus is situated at the posterior or back part of the brain, within the transverse fissure, and is formed by the joining of the superior sagittal sinus, straight sinus, and the two transverse sinuses. This confluence of sinuses allows for the drainage of venous blood from various parts of the brain.

   The circular sinus plays a crucial role in the safe and efficient drainage of deoxygenated blood from the cerebral veins. Specifically, it receives blood from the superior sagittal sinus, which drains the upper part of the brain, and the straight sinus, which drains the deep portions of the brain. Additionally, it also receives blood from the transverse sinuses, which receive venous blood from the cerebellum and the back part of the brain.

   Overall, the sinus circularis is an important anatomical structure that aids in the intricate venous drainage system within the brain. Its circular shape and location at the confluence of multiple sinuses allow for the harmonious flow of blood, ensuring the efficient removal of waste products and maintenance of adequate oxygenation in the brain.

2. (1) A venous ring around the hypophysis, formed by the cavernous and the two intercavernous sinuses; (2) a venous sinus at the periphery of the placenta; (3) s. venosus sclerae.

Etymology of SINUS CIRCULARIS

The term "sinus circularis" is a Latin phrase consisting of two words: "sinus" and "circularis".

1. "Sinus": In Latin, "sinus" refers to a curve, curve or fold, or a bending or recess. It can also mean a bay or gulf, and it is derived from the Proto-Indo-European root *k̂oines- meaning "to bend or curve". The word "sinus" has been used historically in various contexts, including anatomy, geometry, and geography.

2. "Circularis": This Latin word is an adjective derived from the noun "circulus", which means "circle" or "ring". The suffix "-aris" indicates that it pertains to or is related to something, in this case, a circle.
