Question

Foramen of monro is an aperture between
A. Lateral and third ventricle
B. Dicoel and Metacoel
C. Rhinocoel and Dicoel
D. Third and Fourth Ventricle

Answer 1

Foramen of monro is also known as the interventricular Foramen. It is a part of the ventricular system and the connection between the third ventricle and the lateral ventricle. These pared foramina allow for the flow of cerebrospinal fluid. Between lateral ventricles and third ventricles.

Complete answer:
Interventricular foramina are two holes. foramen of Monro is a short conduct between the paired lateral ventricles and the third ventricle of the brain. The development and shape of the ventricular system related to the different development of different parts of the brain along with the ventricular system, ultimately rising from the neural tube. The lateral ventricles stay connected to the third ventricle throughout development.
Walls of interventricular foramina contain choroid plexus; it is a specialized structure that produces cerebrospinal fluid. The choroid plexus of the third ventricle is continuous to the foramina into the lateral ventricles and branches of the medial posterior choroidal arteries, superior choroidal veins. And septal veins also pass through the foramen interventricular foramen give rise to disease when they are narrowed or blocked. Narrowing of the foramina is more common in children.
Most common symptom of blockage is headache. But there are other symptoms of blockage that include fainting, dementia and coma. The development and shape of the ventricular system relates to the differential development of different parts of the brain with the ventricular system ultimately arising from the neural tube.

Hence, the correct answer is option (A).

Note: Foreman of Monroe is also known as interventricular foramen. Foramen of monro is a short conduct between the paired lateral ventricles and third ventricle of the brain. The foramen of Monro is a short conduct between the paired lateral ventricles and the third ventricle of the brain.
