abduction of the shoulder- crucifix on the rings in gymnastics
adduction of the shoulder- second half of a star jump?

Flexion, extension/hyperextension, trabsverse horizontal abduction, circumduction.If you think about the movements that you can do at your shoulder, you can figure this question out yourself. When in the anatomical position, we can perform flexion and extension,the forward and backward (respectively) movements of our arm at the shoulder joint. There is also abduction and adduction, which is the movement of rising our arm out to our sides, away from our body (abduction) and towards our body (adduction). Finally, there is also medial rotation and lateral rotation of the shoulder joint, in which we rotate the head of humerus in the shoulder-joint cavity (glenoid cavity). You may hear the combined movements of flexion, extension, abduction and adduction referred to as circumduction.
Glenohumeral Joint : 55 degs abduction, 30 degs horizontal adductionAcromioclavicular Joint: Arm resting at sideSternoclavicular Joint: Arm resting at side
The shoulder joint is a ball and socket joint, which is the type that allows the greatest range of movement. it allows the arm to move forward and backward (as when you swing your arms while walking); abduction and adduction (as in jumping jacks); and many intermediate movements.
abduction
correct!
Yes it has. The Scapula and humerus forms the shoulder joint and they both coordinate to give overhead abduction, that is abduction above 90 degrees. for every 30 degree movement of the arm or the humerus the scapula moves by 10 degrees. We cannot have overhead abduction is our scapula is stabilized or does not move.
The shoulder joint, being one of the most mobile joints in the body, show quite a lot of versatility in it's movements. It shows flexion(150°-170°), extension (40°), abduction (160°-180°), adduction (30°-40°), lateral rotation (in abduction: 95°; in adduction: 70°) and medial rotation (in abduction: 40°-50°; in adduction: 70°). Flexion is when your muscles bulge, like when you show off your biceps. Extension is the opposite of flexion, when you unbend your elbow. Abduction is when you raise your arm away from your body and adduction is when you lower your arm. Lateral rotation is when you rotate your arm outwards and medial is when you rotate your arm inwards.

The joint between the shoulder and the wrist is the elbow.
It is a triangular muscle covering the shoulder joint, it raises the arm from the side of the body
Ball-and-Socket, the shoulder's cartilage being the socket and the arm's ending being the ball.
