What is lateral ventricle?
What is lateral ventricle?
The lateral ventricles are the largest in the series of four interconnecting fluid-filled cavities within the brain. The function of the ventricles is to house the cerebrospinal fluid (CSF) and provide the passage for its circulation.
Where is the lateral ventricle?
Each lateral ventricle is a C-shaped cavity located deep within the cerebrum. As the lateral ventricle wraps around the thalamus or the central core of the brain, other structures within the ventricle also assume a C-shaped form: the choroidal fissure, the fornix, the caudate nucleus, and the choroid plexus.
What does the lateral ventricle produce?
Cerebrospinal fluid CSF is primarily produced by the choroid plexus of the ventricles (≤70% of the volume); most of it is formed by the choroid plexus of the lateral ventricles. The rest of the CSF production is the result of transependymal flow from the brain to the ventricles.
What are the lateral ventricles separated by?
The 2 lateral ventricles are separated from each other by a thin vertical sheet of nervous tissue called septum pellucidum covered on either side by ependyma. It communicates with the third ventricle through the interventricular foramen of Monro.
What are the horns in the brain?
The lateral ventricles are paired C-shaped structures comprising a body and atrium along with 3 projections into the frontal, temporal, and occipital lobes, termed “horns.” The lateral ventricles communicate with the third ventricle through the interventricular foramina of Monro.
Where is the 3rd ventricle located?
the brain
The third ventricle is a narrow, funnel-shaped structure that lies in the center of the brain. It lies below the corpus callosum and body of the lateral ventricles, between the two thalami and walls of hypothalamus, and above the pituitary and midbrain (Fig. 28-1).
What connects the lateral ventricles to each other?
The interventricular foramina (also called the foramina of Monro) connect the lateral ventricles to the third ventricle through which the cerebrospinal fluid can flow.
What structures are isolated in the lateral ventricles of the brain?
