In the human brain, the cerebral aqueduct passes through:
(a) Corpus callosum
(b) Cerebral hemispheres
(c) Midbrain
(d) Spinal cord

Options

A. Corpus callosum
B. Cerebral hemispheres
C. Midbrain
D. Spinal cord

Answer

To solve the question regarding where the cerebral aqueduct passes through in the human brain, we can follow these steps:

### Step 1: Understand the Function of the Cerebral Aqueduct
The cerebral aqueduct, also known as the aqueduct of Sylvius, is a narrow channel in the brain that connects the third ventricle to the fourth ventricle. It plays a crucial role in the circulation of cerebrospinal fluid (CSF).

**Hint:** Remember the role of the cerebral aqueduct in connecting different parts of the brain.

### Step 2: Identify the Location of the Cerebral Aqueduct
The cerebral aqueduct is located in the midbrain region of the brainstem. It runs through the midbrain and is situated between the two halves of the brain.

**Hint:** Consider the anatomical location of the midbrain in relation to the cerebral aqueduct.

### Step 3: Analyze the Options Given
Now, let's analyze the options provided:
- (a) Corpus callosum: This structure connects the left and right cerebral hemispheres but does not contain the cerebral aqueduct.
- (b) Cerebral hemispheres: The cerebral aqueduct does not pass through the hemispheres; it is located in the brainstem.
- (c) Midbrain: This is the correct answer as the cerebral aqueduct passes through this part of the brain.
- (d) Spinal cord: The spinal cord is not part of the brain and does not contain the cerebral aqueduct.

**Hint:** Eliminate options that do not relate to the midbrain.

### Step 4: Conclusion
Based on the analysis, the correct answer is (c) Midbrain, as the cerebral aqueduct directly passes through this region of the brain.

**Final Answer:** (c) Midbrain
