MAJOR MUSCLE GROUPS WORKSHEET
MAJOR MUSCLE GROUPS WORKSHEET, Reflection questions and surface anatomy
This worksheet will guide your note-taking for the Major Skeletal Muscles slideshow. Be sure to include drawings or sketches of your muscle groups. It will help you when you are studying this material in the future. Your drawings do not need to be fancy. You can make simple stick figures with arrows pointing to the location of the muscle group if you wish.
1. Axial muscles are skeletal muscles of the Trunk or Head .
2. The Trapezius is a large superficial muscle that extends from the occipital bone to the lower thoracic vertebrae and to the spine of the scapula. (Include sketch of muscle location in the box provided.)
4. The actions of the trapezius are Its functions are to move the scapulae and support the arm .
5. The Pectoralis major is a fan-shaped muscle on the chest, making up the bulk of the male chest and found under the breast in a female.
6. The actions of the pectoralis major are The pectorals are predominantly used to control the movement of the arm, with the contractions of the pectoralis major pulling on the humerus to create lateral, vertical, or rotational motion
7. The pectoralis minor is a thin, triangular muscle found deep in, or underneath, the pectoralis major.
8. The actions of the pectoralis minor are he primary actions of this muscle include the stabilization, depression, abduction or protraction, upward tilt, and downward rotation of the scapula. .
9. The dorsi , commonly known as "lats," are large, flat muscles posterior to the arm and partly covered by the trapezius. This is the thin muscle in the back.
10. The actions of the latissimus dorsi are The primary function of the lat is the adduction of the arm, which is often used when performing a pull-up or chin-up or when pulling a heavy object down from a
