CHOROIDAL FISSURE Meaning and
Definition
-
The choroidal fissure is a prominent anatomical feature within the brain. It refers to a narrow, elongated cleft or gap that runs along the length of the lateral ventricle, a cavity located within each cerebral hemisphere. It serves as a key point of communication between the lateral ventricles and the third ventricle, another cavity within the brain.
The choroidal fissure is primarily responsible for the passage of cerebrospinal fluid (CSF), a clear fluid that nourishes and protects the brain and spinal cord. It allows CSF to flow from the lateral ventricles to the third ventricle, facilitating optimal distribution throughout the central nervous system.
This fissure is bordered by the choroid plexus, a structure that produces CSF, and is covered by the ependymal lining of the ventricles. The choroid plexus, positioned within the fissure, secretes CSF into the lateral ventricles. From there, the fluid traverses the choroidal fissure to reach the third ventricle.
Understanding the choroidal fissure is crucial for comprehending the overall structure and function of the brain's ventricular system. It plays a vital role in maintaining proper hydrocephalus, ensuring the appropriate balance and circulation of CSF. Furthermore, abnormalities or impairments in this area can lead to various neurological disorders and pathologies, making it an important focus area for medical examination and research.

Etymology of CHOROIDAL FISSURE
The word "choroidal fissure" consists of two main components: "choroidal" and "fissure".
1. Choroidal: The term "choroidal" originates from the Greek word "khoroeidēs", which means "like a membrane". It is derived from "khōra", which refers to "chorion" or "membrane". In the context of anatomy, "choroid" refers to the vascular layer of tissue located between the sclera (white outer covering of the eye) and the retina (inner layer of the eye). The term "choroidal" is used to describe anything related to the choroid.
2. Fissure: The word "fissure" is derived from the Latin word "fissura", which means "a long, narrow opening, crack, or split". It refers to a narrow separation or groove in a structure.
