Question

The cavity of diencephalon is known as
A. I ventricle
B. II ventricle
C. III ventricle
D. iter.

Answer 1

The diencephalon is the region of the embryonic vertebrate neural tube that gives rise to anterior forebrain structures. The diencephalon is located deep within the cerebral hemispheres and encloses a cavity.

Complete answer:
To answer this question, first, we need to know about the diencephalon. The human brain is the central organ of the human nervous system. One specific structure that defines the duality of the brain is the diencephalon. It is the caudal part of the forebrain (prosencephalon) that covers the central region of the brain. The diencephalon is composed of the epithalamus, thalamus, subthalamus, metathalamus, hypothalamus.

Now, let us find the solution from the option.
The III ventricle is one of four linked fluid-filled cavities consisting of the ventricular system within the brain.
II ventricle is a median divider in the diencephalon between the two thalami and is filled up with CSF (cerebrospinal fluid). It is in the outline, among the left and right lateral ventricles.
Iter is the passage between the third and fourth ventricles in the brain, the aqueduct of Sylvius or cerebral aqueduct.

Thus, the correct option is C. i.e. III ventricle

Note: The diencephalon functions as a main running and functioning center for sensory information and autonomic control. The plethora of connecting pathways among these organelles and other body parts develops the diencephalon an effectively diverse area.
