Explanation:
The correct answer is option 'D', which states that the flight muscles of birds attach the wings to the breastbone. Let's explain this answer in detail:
1. Flight Muscles in Birds:
Birds have specialized flight muscles that enable them to fly. These muscles are responsible for the movement and control of the wings during flight. The two main flight muscles in birds are the pectoralis major and the supracoracoideus.
2. Pectoralis Major Muscle:
The pectoralis major muscle is the main flight muscle in birds. It is a large muscle that attaches the wings to the breastbone or sternum. This muscle is responsible for the downward stroke of the wings during flight, providing the power and force required for lift and propulsion.
3. Supracoracoideus Muscle:
The supracoracoideus muscle is another flight muscle in birds. It is a smaller muscle located on top of the pectoralis major muscle. This muscle is responsible for the upward stroke of the wings during flight, providing the necessary lift and maneuverability.
4. Attachment of Wings to the Breastbone:
Both the pectoralis major and the supracoracoideus muscles work together to move the wings during flight. These muscles attach the wings to the breastbone or sternum, which is a strong and rigid bone located in the center of the bird's chest.
5. Function of the Flight Muscles:
When the flight muscles contract, they cause the wings to move in a coordinated manner. The downward stroke of the wings is powered by the contraction of the pectoralis major muscle, while the upward stroke is powered by the contraction of the supracoracoideus muscle. This alternating motion of the wings allows the bird to generate lift and propel itself through the air.
Conclusion:
In conclusion, the flight muscles of birds attach the wings to the breastbone or sternum. These muscles, namely the pectoralis major and the supracoracoideus, are responsible for the movement and control of the wings during flight. They work together to provide the necessary power, lift, and maneuverability for birds to fly.
