The spelling of "foramen interventriculare" can appear intimidating, but the IPA phonetic transcription can help to break it down. The word is pronounced /fɔːreɪmən ɪntəvɛnˈtrɪkjʊlərɪ/. The first syllable is "for", which is pronounced with a long "o" sound. The second part of the word is "amen", pronounced with a short "a" sound. The final part is "interventriculare", which is broken down into smaller syllables. Each syllable is pronounced carefully, with emphasis on the "tric" sound. With practice, the spelling of this word becomes less daunting!
The foramen interventriculare, also known as the interventricular foramen or foramen of Monro, is a small passage or opening that connects the two lateral ventricles of the brain to the third ventricle. It is a crucial anatomical structure located within the medial wall of the lateral ventricles where they meet the third ventricle.
The foramen interventriculare allows for the exchange and circulation of cerebrospinal fluid (CSF) between the lateral ventricles and the third ventricle. CSF, a clear fluid that surrounds and protects the brain and spinal cord, serves various functions including cushioning the brain against mechanical forces and transporting nutrients. Through the foramen interventriculare, CSF flows from the lateral ventricles into the third ventricle, filling and bathing the areas surrounding the brain.
This opening is bordered by two structures: the anterior wall formed by the column of the fornix, and the posterior wall formed by the anterior nucleus of the thalamus. The foramen interventriculare is a relatively small opening that measures approximately 1.5 to 2.5 mm in diameter in adult humans.
The foramen interventriculare plays a critical role in maintaining the balance and regulation of cerebrospinal fluid within the brain. Blockages or abnormalities in this opening can lead to the accumulation of CSF in certain areas, causing conditions such as hydrocephalus, a condition characterized by an abnormal buildup of fluid in the brain.
Interventricular f., f. of Monroe, a communication between the third and the lateral ventricles on either side, passing from the upper and anterior part of the lateral wall of the third ventricle outward and upward between the anterior pillars of the fornix and the anterior tubercles of the thalami.

The term "foramen interventriculare" is derived from Latin.
1. "Foramen" is the Latin word for "opening" or "hole". It comes from the verb "forare", which means "to pierce" or "to bore through".
2. "Interventriculare" is a combination of two Latin words:
- "Inter" means "between" or "among".
- "Ventriculare" is derived from the Latin word "ventriculus", which means "ventricle". The word "ventricle" refers to a small cavity, typically used to describe the cavities that make up parts of the brain.
In the case of "foramen interventriculare", the term refers to an opening or hole located between the ventricles of the brain.
