and then there are the neural Pathways from skin from the tendons and insert of the muscles onto bone within the muscles that register how much stretch are on our muscles and those are the soall sensory inputs that come into the dorsal part of the spinal cord the part that is facing toward our back and that sensory information tells our spinal cord which then informs our brain whether or not our limbs are extended too far and about to snap or whether or not a muscle is loaded too heavy and is about to be pulled off the bone and in that case the brain and spinal cord have these magnificent mechanisms to shut down the neurons so that you know we drop the load so that we don't overwhelm the muscle and rip it off the bone or we don't stretch our limbs too far
