Detailed explanation-1: -Flexion. Forward and upward movement of the humerus on the glenoid in the sagittal plane.
Detailed explanation-2: -It is directed laterally and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest.
Detailed explanation-3: -The shoulder joint, also known as the glenohumeral joint, is a synovial triaxial (polyaxial) joint. It is formed by the glenoid fossa of the scapula meeting the head of the humerus. It allows motion in all three cardinal planes: flexion/extension in the sagittal plane.
Detailed explanation-4: -What is the proper position of the Humerus for the inferosuperior Axial Projection? Abducted to a right angle and externally rotated.
