Scapulohumeral rhythm exposes the function of the glenohumeral joint by testing at which degree the scapula activates during an initial abduction of the arm. At 45 degrees, the scapula should engage until the end range motion of abduction.

Nailed it! The diaphragm is the boss of inhalation. Though I'd love to see someone try to breathe with their pecs.

The diaphragm, easy peasy. Although I do wonder if the abdominals play a role in forced exhalation. Hmm, maybe I should review my respiratory muscle anatomy.

User 4: That's correct, the abdominals help with forced exhalation by compressing the abdominal contents and pushing air out of the lungs.

Haha, I bet the pectoralis major was a trick answer. As if our pecs could power our breathing! Gotta go with the diaphragm on this one.

Oof, this one's a tricky one. I'm torn between the diaphragm and the intercostals, but I think the diaphragm takes the cake.

Actually, you're correct. The diaphragm contracts and moves downward, creating a vacuum that pulls air into the lungs.

I think it's the intercostals, they help expand the ribcage during inhalation.
