Question

question 8 of 10
which of the following is part of the midbrain?

a. brainstem

b. pons

c. reticular activating system

d. corpus callosum

Explanation:

• Option A: The brainstem includes the midbrain, pons, and medulla, but the brainstem itself is not a part of the midbrain (the midbrain is part of the brainstem).
• Option B: The pons is a separate part of the brainstem, not the midbrain.
• Option C: The reticular activating system (RAS) has components in the midbrain (along with other brainstem regions), so it is associated with the midbrain.
• Option D: The corpus callosum connects the two cerebral hemispheres and is not part of the midbrain.

Answer:

C. Reticular activating system
