Document Summary
2 types of proprioceptors are: somatosensors tells us about hot and cold and pressure. There are somatosensors in our tendons and muscles, they tell us if a muscles is contracting or extending: vestibular apparatus located in our ears. We have 3 semicircular canals in our ears. They give us info about how our body is moving and helps us detect rotational acceleration in 3 separate planes. Our anterior canal has to do with movement when nodding yes. When doing a somersault, our anterior canal will give us information saying we are doing a somersault. Our posterior canal will tell us the speed we are moving at when moving head from shoulder to shoulder. The lateral canal is used when you turn your head in a no movement. When you stop spinning, fluid in the ear moves in the opposite direction, making you feel like you are still spinning.
