What are the bones and muscles involved in the movement of birds when they spread their wings and fl

The bones are hollow and light. The pectoral muscles are well developed. There are air bags.

1. The forelimbs evolved into wings for flight, and the pectoral muscles are well developed.

2. The body has evolved into a streamlined shape.

3. The bones are hollow and the bone walls are thin, so as to facilitate weight loss.

4. The body temperature is high, which is conducive to the production of energy.

5. The body has evolved an air bag to assist breathing and improve the oxygen supply during flight.

Wrong. Although the suprawing muscles of birds are poorly developed, they have more other characteristics that are adapted to flying in the air, such as the size and shape of the wings, and the structure of the wing surface. These features are more capable of helping birds to fly in the air than to muscularize their wings.

Hello, it is a pleasure to serve you and give you the following answer: This is right. The muscles on the wings of the bird are conducive to its adaptation to the life of flying in the air, which is the skin trap, because the muscles on the wings of the bird can help the bird control the direction and attitude of flight, so that it can fly in the air.

In order for birds to adapt to the life of flying in the air, the following methods can be taken:1Provide good living conditions for birds:

Provide nutritious food for birds so that they have enough energy to cross large distances, or provide suitable habitats so that they can fly in the air; 2.Cultivating the flight ability of birds: through training, birds can master flight posture and flight routes so that they can fly in the air; 3.

Provide strength to birds: Birds can be given more wing swing training and rich nutrition, so that they can have stronger wing strength and be able to fly in the air; 4.Cultivating Birds' Awareness of Flight:

Birds can be taught the skills to fly skillfully by providing them with flight instructions and instructions. Personal experience: The method of using birds to adapt to life in the air is very effective, which can make birds better adapt to life in the air, so as to improve their survivability.

That's right. The muscular development of birds helps them adapt to life in the air, as they need to flap a lot of their wings in the air, which requires a lot of energy and strength. Therefore, they must have well-developed muscles and thick flesh to support the tremendous force generated by their flight.

In addition, they must have strong stamina that can maintain balance and accuracy, which is achieved by well-developed muscles.

Bird bones are lighter than those of other animals and are streamlined.

Birds are adapted to flight life and have significant specialization in the skeletal system, which is manifested as light and strong bones with gas-filled cavities in the bones. The skull, spine, pelvis, and limb bones heal. The limb bones and girdle bones are more deformed, the skull is thin, light and healed, and the occipital condyle is single.

The spine is divided into five parts: cervical, thoracic, lumbar, recommendary, and caudal vertebrae. The cervical vertebra is a heteroconcave vertebrae, the first one is called the atlas vertebrae, and the second one is called the pivotal vertebrae. The thoracic vertebrae are 5 to 6, and the bony ribs and sternum combine to form the thoracic cage.

Flying birds have well-developed sternum with keel protrusions, and a few thoracic vertebrae, lumbar vertebrae, recommended vertebrae and part of the caudal vertebrae are healed. The bone is a structure unique to birds. Open pelvis.
