The latissimus dorsi muscle aids in adduction by contracting and pulling the humerus (upper arm bone) towards the body's midline. Its fibers run from the lower spine and pelvis to the upper arm, allowing it to effectively draw the arm down and back. When activated, it also assists in internal rotation and extension of the shoulder joint, further enhancing its adductive actions during movements like pulling or rowing.
What else can I help you with?
What muscle is the prime mover and it's correct muscle action involved in pulling down a rebound in a basketball game?
latismus dorsi
Which term does not belong latissimus dorsi pectoralis major synergists adduction of shoulder or antagonists?
The latissimus dorsi and pectorals major are synergists for shoulder adduction
What muscle causes dorsi flexion?
tibialis anterior
What is the large broad sheet of muscle that originates along the thoracic and lumbar vertebrae and inserts upon the humerus?
The large broad sheet of muscle you are referring to is the latissimus dorsi. It is responsible for movements like shoulder extension, adduction, and medial rotation of the arm.
What is the synergist of latissimus dorsi?
The muscle of the pectoralis is antagonist to the latissimus dorsi during the shoulder adduction. The anterior fibers are involved in shoulder abduction when the shoulder is externally rotated.
What is another name for the muscle latissimus dorsi?
Another name for the muscle latissimus dorsi is the "lats." This broad, flat muscle is located in the lower back and is responsible for various movements of the shoulder and arm, including adduction, extension, and internal rotation. It plays a crucial role in activities like pulling and lifting.
Muscle that adducts the shoulder and causes extension of the shoulder joints?
latissimus dorsi
What is the prime mover muscle of shoulder horizontal adduction?
Because shoulder horizontal adduction is performed when the arm is horizontal position (i.e., the elbow is level with shoulder) and adduction is movement toward the center of the body, shoulder horizontal adduction is performed primarily by pectoralis major and anterior deltoid, with an assist by latissimus dorsi.
What muscle starts with L?
The muscle that starts with "L" is the latissimus dorsi. This large, flat muscle is located in the back and is responsible for various movements of the shoulder, including extension, adduction, and internal rotation. It plays a crucial role in activities such as pulling and lifting. The latissimus dorsi also contributes to the V-shape appearance of the back in well-developed individuals.
Prime mover for shoulder flexion and adduction?
Do you mean flexion and (abd)uction?? If so, the prime mover would be the deltoid muscle with many smaller muscles assisting. If you are in fact meaning flexion and adduction, the prime mover would be the pectoralis major and the latissimus dorsi with many smaller muscles assisting.
What muscles cause horizontal adduction of the shoulder?
There are four muscles used for horizontal adduction of the shoulder. These muscles are the pectorals major, middle deltoid, latissimus dorsi, and coracobrachilis.
Where does the latissimus dorsi insert?
The latissimus dorsi muscle inserts primarily onto the intertubercular groove of the humerus. This insertion allows it to play a crucial role in shoulder movements, including adduction, extension, and internal rotation of the arm. Additionally, it has some connections to the fascia of the lower back and can influence the movement of the trunk.
