Which term is described as the 'upper part of the chest'?

• A. Pectoralis Major
• B. Pectoralis Minor
• C. External Rotation
• D. Cranial Base Release

Answer: (B)

Think in terms of location on the chest wall. The pectoralis minor is the smaller muscle that sits right on the upper chest area beneath the larger pectoralis major, stretching from ribs 3–5 to the coracoid process of the scapula. Its position makes it a defining part of the upper chest region, which is why it’s described as the upper chest term. The other options don’t fit this description: the pectoralis major is the main chest muscle but not typically singled out as the upper chest, external rotation is a shoulder movement, and cranial base release relates to the skull, not the chest.
