lateral ventricle
A student points to the lateral ventricle on a large anatomical diagram of the human brain.
Noun: 1. A structure in the brain: One of two large, C-shaped (horseshoe-shaped) cavities filled with cerebrospinal fluid, located one in each hemisphere of the cerebrum. They are part of the brain's ventricular system and connect to the third ventricle.
The term "lateral ventricle" is used in anatomical, medical, and neuroscientific contexts to describe a specific part of the brain's internal structure. - It is typically used with a determiner (e.g., the, a, each) and often specified as left or right. - Example: The cerebrospinal fluid is produced in the choroid plexus within the lateral ventricle.
- Basic Usage:
- An MRI scan clearly showed the size and shape of each lateral ventricle.
- The left lateral ventricle was slightly enlarged compared to the right.
- Medical Context:
- A blockage can prevent cerebrospinal fluid from draining from the lateral ventricles, causing hydrocephalus.
- The surgeon inserted a catheter to drain excess fluid from the lateral ventricle.
- Anatomical Description: The term is used to describe location, morphology, or pathology.
- The body, frontal horn, occipital horn, and temporal horn are the major parts of a lateral ventricle.
- In Research: Used in studies related to neurology, psychiatry, and brain development.
- The study found a correlation between enlarged lateral ventricles and certain neurological conditions.
- Ventricle (noun): A general term for any small cavity in the body, especially in the heart or brain. The lateral ventricles are a specific type of brain ventricle.
- Third Ventricle (noun): The central ventricle of the brain, located in the diencephalon, to which the lateral ventricles connect.
- Fourth Ventricle (noun): A ventricle located between the brainstem and the cerebellum.
- Ventricular System (noun): The entire interconnected system of cavities (ventricles) in the brain containing cerebrospinal fluid.
- There are no direct common synonyms for this precise anatomical term. In general descriptive language, it might be referred to as a brain cavity or cerebral ventricle, but these are less specific.
- Enlarged lateral ventricle(s): A common finding in medical imaging indicating potential pathology.
- Horn of the lateral ventricle: Refers to one of the extensions (frontal, occipital, temporal) of the ventricle.
- Choroid plexus of the lateral ventricle: The vascular structure within the ventricle that produces cerebrospinal fluid.
- Body of the lateral ventricle: The central part of the ventricle.

- either of two horseshoe-shaped ventricles one in each cerebral hemisphere; they communicate with the third ventricle via the foramen of Monro
