This episode really hurts and will prepare you for the emergency case. You will learn what differences bruised, cracked, strained and sprained body parts make. And why you may not want to ask a passer-by for help with either a contusion or concussion. Ligaments & Tendons Ligaments connect different bones with eachother, tendons attach muscles to bones, and - not mentioned in the episode - fasciae link muscles with other muscles.
