Document Summary
Free nerve endings: imp for pain and temp changings. A receptor that cares about and picks up sudden skin displacement and translates it to aps. Adapts quickly, meaning after sudden skin displacement occurs, it stops sending signals to trigger aps. (sudden skin displacement is a touch as opposed to the clothes on our body) Merkel"s disks: the circular disks on the side. Adapts slowly, meaning theyre active for a longer period of time. For some of our sensory info we need immediate info so we can fire and react quickly, and theres other sensory info that we care abt initially but don"t need to worry abt afterwards. If we"re considering this quick adaptation: like when we put our shoes on this morning. We felt the shoes go onto our foot. But after that, sitting here in class, we"re not consciously thinking abt the shoes on our foot.
