THE PHYSICAL EXAM: THIGHS MATTERS
Underneath the spreading tissue is the largest bone in the body, known as the femur. The femur connects the knee to the groin. Now, my use of the phrase, knee to the groin has probably brought out one of two responses in my readers:
- A dull moan accompanied by cold sweats from male readers who had PTSD flashbacks to middle school
- A desire to watch the popular TV show, America’s Funniest Videos, which has built an empire on traumatic groin injuries.
Some scientists believe that the bone in the hair of this child (nicknamed “Pebbles” for unknown reasons) is a femur, noting the similarity to the big honking bone the paleontologist with the sign is standing next to. Others eschew this theory, pointing the lack of the ball-shaped portion of the bone (acetabulum) that inserts into the hip. The first scientists call the second group a bunch of smart-acetabulums, leading to some more knee/groin interactions. Despite the acrimony of this debate, all scientists agree on one thing: that’s one darling little girl.
(Note, astute reader Ngsurgery corrected me on this one, as the ball portion is actually the head of the femur, while the acetabulum is the socket the head goes into. I won’t change it, as it would make the smart-acetabulum pun drop in its funniness quotient. I appreciate sharp readers pointing out my brain farts).
The femur isn’t the only part of the thigh with size as it’s claim to fame. The sartorius muscle, in its circuitous course from outer pelvis to inner knee, is the longest muscle in the body.
