What reduces the angle between two bones?

among the limbs, buckling Decrease the angle between the bones (joint flexion), while stretching increases the angle and straightens the joint.

Which muscles do stretches?

Stretching is done through actions Serratus anterior, pectoralis major, and pectoralis minor. Retraction is accomplished through the action of the trapezius, rhomboids, and latissimus dorsi. Raising is done by the trapezius, levator scapulae, and rhomboids.

Which joints can be stretched?

What is an example of hyperextension?

hyperextension injury When the joint moves beyond its normal extension angleFor example, this can happen to the elbow during exercise, usually when « pumping » or practicing a tennis swing. The injury known as « tennis elbow » is actually a hyperextension injury.

• Infraspinatus.
• teres minor.
• subscapularis muscle.

Which muscle is in the arm?
