The human body is an amazing thing. We’re really just a pile of bones held together by muscles and ligaments. Our heads are attached to our bodies only by the action of muscles. Likewise, our arms and legs do not sprout out of our trunks like branches out of a tree. Our limbs are created from a complex and elegant interplay of muscles, which attach via tendons to different bones, and connect the peripheral parts of our bodies to our core. Our muscles contract this way and that, each having its own role in extension, flexion, rotation or what have you. I find it fascinating that our bones are basically floating about in our bodies, only anchored by the action of our muscles. I think of how floppy my babies were when they were born, and how they could barely move intentionally, and how they then gradually learned to lift their heads, then their upper bodies, then they crawled, and then the extensors of the legs were strong enough for that first little push to standing. Absolutely fascinating.
