Corpora quadrigemina is found in …………..portion of ………….. .

Options

A. Ventral , Forebrain
B. Ventral, Midbrain
C. Dorsal, Forebrain
D. Dorsal, Midbrain

Answer

To solve the question "Corpora quadrigemina is found in …………..portion of …………….", we need to identify the correct anatomical location of the corpora quadrigemina within the brain.

### Step-by-Step Solution:

1. **Understanding the Structure**:
- The corpora quadrigemina consists of four rounded swellings located in the brain. These are known as the superior and inferior colliculi.

2. **Identifying the Brain Regions**:
- The human brain is divided into three main parts: the forebrain, midbrain, and hindbrain.
- The midbrain is located between the forebrain (which includes structures like the thalamus and hypothalamus) and the hindbrain (which includes structures like the pons and cerebellum).

3. **Locating the Corpora Quadrigemina**:
- The corpora quadrigemina is specifically located in the dorsal portion of the midbrain. This is where the superior and inferior colliculi are found.

4. **Filling in the Blanks**:
- The first blank refers to the portion of the midbrain, which is "dorsal".
- The second blank refers to the part of the brain, which is "midbrain".

5. **Final Answer**:
- Therefore, the complete answer is: "Corpora quadrigemina is found in the dorsal portion of the midbrain."
