Katie loves pretending that she’s a human cannonball. As she jumps off the diving board, she assumes the proper position before she pounds into the water: head and thighs tucked against her chest; back rounded; arms pressed against her sides while her forearms, crossed in front of her shins, hold her legs tightly folded against her chest. Use the proper anatomical terms to describe the position of Katie’s back, head, and free limbs.
Is movement required for life? Why
Andy, a 55-year-old, 75 kg (165-pound) roofer, is shingling the steeply pitched roof of a new house when he loses his footing and slides down the roof and over the edge, feet first. He braces himself for the fall, and when he hits the ground, he cries out and doubles up in excruciating pain. Emergency medical technicians called to the scene tell him he has broken his hips. Describe, more specifically,where his fractures most likely occurred.On the way to the hospital, Andy says,“You know it’s funny, when I was a kid,I used to jump off roofs that high, and I never got hurt.” Why do you think Andy was more at risk of a fracture as an adult than he was as a boy?
