Principal superficial skeletal muscles?
The principal superficial skeletal muscles include the major muscle groups that are closest to the skin and responsible for voluntary movements. Key examples are the pectoralis major in the chest, the deltoids in the shoulders, the biceps brachii in the arms, and the rectus abdominis in the abdomen. These muscles play crucial roles in actions such as lifting, pushing, and stabilizing the body. Their superficial location makes them easily identifiable and important for both movement and aesthetics.

The muscles found directly under the skin are known as the subcutaneous muscles, which include the platysma in the neck and the superficial fascia in other areas of the body.

They are not typically involved in major body movements but play a role in the overall appearance and function of the skin.
What two muscles lie superficial to the buccinator?
