Question

Control and co-ordination of head movements in response to visual and auditory stimuli is carried out by ______________.

• A. corpora striata
• B. corpora cavernosa
• C. crura cerebrii
• D. corpora quadrigemina

Hint:

Corpora quadrigemina = visual + auditory reflex centre of midbrain.

Answer 1

The Correct Option is D

Step 1: Understanding corpora quadrigemina.
Corpora quadrigemina is a part of the midbrain and consists of four rounded bodies.
Step 2: Functional role.
The superior colliculi are involved in visual reflexes, while the inferior colliculi are involved in auditory reflexes.
Step 3: Coordination of movements.
These structures help in reflex movements of head and neck in response to visual and auditory stimuli.
Step 4: Conclusion.
Therefore, control and coordination of head movements is carried out by corpora quadrigemina.
