Which of the following is NOT included in the organization of the head, neck, and shoulders?

The organization of the head, neck, and shoulders encompasses several key elements that contribute to effective movement and posture. Postural alignment involves how the head, neck, and shoulders relate to the rest of the body and is crucial for maintaining balance and reducing strain. Scapular mobility refers to the movement and positioning of the shoulder blades, which is integral to shoulder function and overall upper body mechanics. Head and neck alignment is also essential, as it influences the rest of the spine and overall posture.

Shoulder width expansion, however, is not typically recognized as a core component of the organization of these areas. While it may play a role in overall upper body mechanics or aesthetics, it does not directly pertain to the alignment or functional mobility aspects necessary for effective movement patterns in the head, neck, and shoulders. Consequently, it doesn't belong to the fundamental considerations when addressing posture and alignment in this context.
