Question

How many cerebral ventricles do humans have?

• A. 2
• B. 3
• C. 4
• D. 5

Hint:

The four ventricles (two lateral, third, and fourth) are interconnected and play a vital role in maintaining the homeostasis of the brain's environment.

Answer 1

The Correct Option is C

Humans have a total of 4 cerebral ventricles.

These include:

1. Two lateral ventricles (one in each hemisphere of the brain)
2. One third ventricle (located in the midline of the brain, between the two thalami)
3. One fourth ventricle (located between the brainstem and the cerebellum) These ventricles are filled with cerebrospinal fluid (CSF), which helps in cushioning the brain, removing waste products, and maintaining a stable chemical environment.

Thus, the correct answer is (c) 4.
