VENTRICULUS LATERALIS Meaning and
Definition
-
The term "ventriculus lateralis" refers to a specific anatomical structure found in some organisms, particularly in teleost fish and amphibians.
The ventriculus lateralis, also known as the lateral ventricle, is a fluid-filled cavity located within the brain. It is part of the brain's ventricular system, which consists of a series of interconnected chambers filled with cerebrospinal fluid (CSF). In the case of teleost fish and amphibians, these lateral ventricles are the largest among the ventricles.
The ventriculus lateralis is typically paired, with one situated in each cerebral hemisphere. Each ventricle is lined by a layer of specialized cells called ependymal cells, which are involved in the production and circulation of CSF. The ependymal cells play an essential role in maintaining the internal environment of the ventricles and the brain, as well as providing a protective barrier.
The CSF present within the ventriculus lateralis serves several crucial functions. It provides buoyancy to the brain, acting as a shock absorber against mechanical forces. Additionally, the fluid aids in the exchange of nutrients and waste products between the brain and the systemic circulation.
Understanding the ventriculus lateralis and its role in the brain's ventricular system contributes to the knowledge of neuroanatomy and physiology in various organisms. It provides insights into the organization and function of the brain, as well as potential implications for neurological diseases and disorders.

Lateral ventricle, a cavity in the interior of each cerebral hemisphere, communicating through the foramen of Monro with the third ventricle; it has four indistinctly separated parts, the pars centralis (cella media) and three cornua-anterior, posterior, and inferior or descending.

Common Misspellings for VENTRICULUS LATERALIS
Etymology of VENTRICULUS LATERALIS
The term "ventriculus lateralis" is derived from Latin. Here is the breakdown:
- "Ventriculus" comes from the Latin word "venter", which means "belly" or "stomach". In anatomy, it refers to a cavity or hollow structure.
- "Lateralis" is a Latin word that means "side" or "pertaining to the side".
Therefore, when combined, "ventriculus lateralis" translates to "lateral ventricle" in English, referring to a cavity or hollow structure situated on the side. This term is commonly used in the field of anatomy, particularly in reference to the ventricular system in the brain.
