Optic recess
Optic Recess
The Optic Recess (pronunciation: /ˈɒptɪk/ /ˈriːsɛs/) is a significant anatomical structure in the brain that plays a crucial role in the visual system.
Etymology
The term "Optic" is derived from the Greek word "optikos," which pertains to vision, while "Recess" is from the Latin word "recessus," meaning a going back or retreat.
Definition
The Optic Recess is a small indentation located in the diencephalon, specifically in the third ventricle of the brain. It is situated anterior to the infundibulum and is where the optic chiasm is located.
Function
The primary function of the Optic Recess is to house the optic chiasm, a crucial part of the visual pathway where the optic nerves partially cross. This structure allows the transmission of visual information from the eyes to the brain.
