Q. In birds, which muscle is well developed?

NTA AbhyasNTA Abhyas 2020Locomotion and Movement

Solution:

Birds have two important flight muscles, the Musculus pectoralis/ Pectoralis major for the downstroke and the smaller Musculus supracoracoideus for the upstroke. Musculus pectoralis the larger and the most powerful. It is an immensely developed triangular muscle of the breast. Depending on flight or diving behaviour, there is a considerable variation in built and size of these muscles.
