What muscles move bones and body parts?

Skeletal muscles are the muscles that move bones and body parts. They are attached to bones by tendons, and when they contract, they pull on the bones to move them. There are three main types of skeletal muscles:

* Agonist muscles are the muscles that are responsible for producing a particular movement. For example, the biceps brachii muscle is the agonist muscle for elbow flexion.

* Antagonist muscles are the muscles that oppose the action of the agonist muscles. For example, the triceps brachii muscle is the antagonist muscle for elbow flexion.

* Synergist muscles are muscles that help the agonist muscles to produce a particular movement. For example, the brachioradialis muscle is a synergist muscle for elbow flexion.

Skeletal muscles are voluntary muscles, which means that they can be controlled consciously. This allows us to move our bodies in a variety of ways, such as walking, running, jumping, and throwing.

Skeletal muscles are also responsible for maintaining posture. They keep our bodies in an upright position and prevent us from slumping over.

In addition to moving bones and body parts, skeletal muscles also play a role in thermoregulation. When we exercise, our skeletal muscles produce heat, which helps to keep our bodies warm.
