Interventricular foramen
(Redirected from Interventricular foramina)
Interventricular foramen
The interventricular foramen, also known as the foramen of Monro, is a crucial structure in the human brain that connects the lateral ventricles to the third ventricle. This foramen allows the passage of cerebrospinal fluid (CSF) between these ventricles, playing a vital role in the ventricular system of the brain.
Anatomy[edit | edit source]
The interventricular foramen is located near the midline of the brain, situated between the thalamus and the fornix. Each lateral ventricle has its own foramen of Monro, leading into the third ventricle. The foramen is bordered anteriorly by the column of the fornix and posteriorly by the anterior thalamic tubercle.
Function[edit | edit source]
The primary function of the interventricular foramen is to facilitate the flow of cerebrospinal fluid from the lateral ventricles into the third ventricle. This flow is essential for maintaining the homeostasis of the brain's internal environment, providing cushioning, and removing metabolic waste.
Clinical Significance[edit | edit source]
Blockage or narrowing of the interventricular foramen can lead to a condition known as hydrocephalus, where the accumulation of cerebrospinal fluid causes increased pressure within the brain. This can result in symptoms such as headaches, nausea, and cognitive impairments. Treatment may involve surgical procedures such as the insertion of a ventriculoperitoneal shunt to divert the excess fluid.
