The ribcage greatly defines the size and shape of the thorax of the human figure.
The ribcage has two main openings. The larger opening at the bottom is called the outlet. The smaller opening around the top is called the inlet.
The opening of the inlet kinda slopes downward as it goes forward… so if you look at the ribcage from the front, you could see the back part of the inside… kinda like the collar of a V-neck shirt.
According to accomplished portrait painter John Raynes, “In females, the thorax is generally smaller, actually and proportionately, to the rest of the body, and the slope of the inlet is greater.“
I wonder if this has any bearing on how low the clavicle is in the human figure. I’ll have to update you guys on that in the future.
