Here's a more detailed breakdown:
* Head and Neck: Muscles responsible for facial expressions, chewing, and head movement.
* Trunk: Muscles that control posture, breathing, and movement of the spine and rib cage.
* Upper Limbs: Muscles that allow for movement of the shoulders, arms, hands, and fingers.
* Lower Limbs: Muscles that enable movement of the hips, legs, feet, and toes.
It's important to note that skeletal muscles are not located within the body cavities, such as the chest cavity or abdominal cavity. They are external to these cavities.
