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.
No. Winging Posterior movement of the medial border of the scapula, Rotation about a vertical axis. Tipping Posterior movement of the inferior angle of the scapula, Rotation about a transverse axis
The medial border of the scapula is what does not articulate on the scapula with any other bone. It is actually parallel to the vertebrae column and because it does not articulate the arms as well as shoulders have move movement.
Yes, both upward and lateral rotation are used to describe the same movement of the scapula. It's the movement of the scapula away from the midline.
stabilizes, raises, retracts, and rotates scapula; adducts scapula and elevates /depresses scapula stabilizes, raises, retracts, and rotates scapula; adducts scapula and elevates /depresses scapula
Moves shoulder away
The patella is the knee-cap and protects the knee joint. The scapula is the shoulder blades and is related to arm and shoulder movement.
Your scapula is your shoulder blade. So any swelling in the top of your back or by your shoulder joint.
To allow greater freedom of movement for the scapula and hence gives the ability to run at higher speeds.
The frog doesn't have a scapula
The scapula, also known as the shoulder blade, is a flat bone located on the upper back. Its main function is to provide attachment points for muscles that control shoulder movement, such as the deltoid and rotator cuff muscles. Additionally, the scapula helps stabilize and support the shoulder joint, allowing for a wide range of arm movements.
The movable pectoral girdle bones are the scapulae and the clavicles. These bones must have a range of movement in order to allow the upper body to function properly.
