At the sides of the chest, the breast tissue can extend into the axilla (armpit), and can reach as far to the back as the latissimus dorsi muscle, extending from the lower back to the humerus bone (the bone of the ...
These factors result in women's waist–hip ratio (WHR) being lower than for males, although males tend to have a greater upper-body to waist–hip ratio (WHR) giving them a V shape look because of their greater muscle mass (e.g., they generally have much larger, more muscular and broader shoulders, pectoral muscles, teres major muscles and ...
