A Viral Video Explains in Detail Why Humans Have Such Big Butts

When it involves butt measurement, some persons are extra genetically gifted than others. And then there are those that practice their decrease physique laborious, squatting and lunging their approach to the massive butt of their goals. But do you know that we even have the most important butts in the whole animal kingdom? When it involves the butt-to-body-size ratio, human beings bought again.

In a brand new YouTube video from the Institute of Human Anatomy, co-founder Jonathan Bennion and lab director Justin Cottle supply a primer on gluteal anatomy utilizing a cadaver, and clarify why the human booty is as large as it’s.

The high layer of the butt is the pores and skin, or dermis and dermis. Under that is the subcutaneous layer often known as the hypodermis, comprised of fatty tissue which may be as much as inches thick relying on the individual. “This is not the reason why people have big butts,” says Bennion, pointing to the subsequent layer down—the gluteus maximus—as the actual purpose.

Of course, this simply begs one other query: why is the gluteus maximus so giant in people? “That answer comes down to how the gluteus maximus functions with how we walk and move,” says Bennion, utilizing a skeleton as an example how the muscle mobilizes the hip joint to trigger extension of the legs. And as a result of we, as bipedal creatures, stand with our legs in an prolonged place, which means the gluteus maximus is being continually engaged.

“The gluteus maximus is always buzzing, activated, to keep us in this upright extended position,” says Bennion. “When you walk, run, or go on a full-fledged sprint, the gluteus maximus has a really important job, again, to maintain this upright position.”
