Document Summary

Motor systems how the nervous system controls our body. What something is tuned to pick up. Meissner corpusle and merkel sit close to the surface. When these receptors are activated that gives rise to the sense of touch there are other things we can feel like pain which is activated by damaging stimuli physiologist call this high threshold. Meisnner and merkel are close to the epidermis in the protrusions the meisner is non neural cell forms a complicated ending which confers the type of energy it responds to and how it does so. Mechanical force will open the channel up and allow na in proteins are tetherd to the internal and extracellular matrix. When force is applied they can be opened and closed. Main difference is the way they respond. When a stimulis comes on we care about the onset some mecahnoreceptors are slowly adapting the 4 mechanoreceptors.
