In my research. Abduction, in functional anatomy, is a movement which draws a limb away from the median (Sagittal) plane of the body. It is thus opposed to adduction.
There are two muscles that move the arm away from the body (abduction), the supraspinatus and the deltoid.
deltoid
Coracobrachialis Muscle
In the canine: the gluteal muscles (superficial, middle, deep).
Flexion, abduction, and lateral rotation at the hip, and flexion and medial rotation at the knee.
The major muscle that abducts the humerus is the Deltoid. (all muscles move in conjuction, there may be more muscles that contribute to the abduction of the humerus) pectoralis major and latissimus dorsi
Abduction Abduction also means "away from the body"
Kidnapping.
Abductor muscles are the muscles which cause abduction. prime example being lateral head of the shoulder abducts your arms to the side of your body. similarly you have the muscles in your lower body which abducts your legs to the sides.
Nothing, but if you are tilted or upside down then gravity will abduct it.
The major muscle that abducts the humerus is the Deltoid. (all muscles move in conjuction, there may be more muscles that contribute to the abduction of the humerus) pectoralis major and latissimus dorsi
The middle part of the deltoid abducts the shoulder, as well as shoulder abduction at the supraspinatus and biceps brachii muscles.
