Question

In cockroach, depression of wings is due to contraction of

• A. Dorsoventral muscles
• B. Alary muscles
• C. Dorsolongitudinal muscles
• D. Adductor muscles

Hint:

In cockroaches, understand the specific muscles responsible for wing movement: dorsolongitudinal muscles play a key role in wing depression.

Answer 1

The Correct Option is C

Step 1: In cockroaches, the depression of the wings occurs due to the contraction of the dorsolongitudinal muscles, which results in the movement of the wings downwards.
Step 2: The dorsoventral muscles contract for other movements but are not directly responsible for wing depression.
Step 3: The alary muscles and adductor muscles have different functions in the movement of wings and legs respectively.
