multiple choice question
the two pairs of rounded knobs indicated in the figure are part of the

olive

red nucleus

corpora quadrigemina

cerebral peduncle

Explanation:

The corpora quadrigemina consists of two pairs of rounded knobs (superior and inferior colliculi) located on the dorsal surface of the midbrain. The olive is a structure in the medulla, the red nucleus is a midbrain structure but not in knob - like pairs, and the cerebral peduncle is a different midbrain structure. So the two pairs of rounded knobs are part of the corpora quadrigemina.

Answer:

C. corpora quadrigemina
