What are the coordinate muscles of body?

Coordinate muscles of body are voluntary muscles that work together to produce coordinated movements. They are innervated by the somatic nervous system and are responsible for activities such as walking, running, and reaching.

The major coordinate muscles of the body include the:

- Skeletal muscles: These muscles attach to bones and are responsible for moving them.

- Smooth muscles: These muscles are found in the walls of internal organs, such as the stomach and intestines, and are responsible for controlling the flow of materials through these organs.

- Cardiac muscles: These muscles are found in the heart and are responsible for pumping blood throughout the body.

These muscles work together to produce coordinated movements. For example, when you walk, the gluteal muscles (in the buttocks) contract to extend the hip joint, the quadriceps muscles (in the front of the thigh) contract to flex the knee joint, and the gastrocnemius muscles (in the back of the calf) contract to extend the ankle joint. These coordinated movements allow you to walk forward.
