Biology - Neural Control and Coordination Question with Solution | TestHub

The medulla oblongata is the lower part of the brainstem. Like the spinal cord, it has grey matter on the inner side and white matter on the outer side.

The medulla oblongata encloses the ${\text{IV}}^{th}$ ventricle, not the ${\text{III}}^{rd}$ ventricle. The ${\text{III}}^{rd}$ ventricle is enclosed by the diencephalon.

The roof of the medulla contains the posterior choroid plexus, which secretes cerebrospinal fluid (CSF).

The roof of the ${\text{IV}}^{th}$ ventricle in the medulla has a median aperture known as the foramen of Magendie.

Therefore, the statement that it encloses the ${\text{III}}^{rd}$ ventricle is incorrect.

Answer: It encloses ${\text{III}}^{rd}$ ventricle.
