posterior spinal root.

Motor radicular area  (area radicu-

karis motoria)  is  the  muscles  (my-

otome) that are innervated by one

– react to changes in the external and internal environments

– transduce these changes to acti on potenti als, which pass informati on to the CNS 

Division according to the locati on of the sti mulus:

1 Exteroreceptors – receptors that react to sti muli in the external environment 

2 Interoreceptors – receptors that react to sti muli in the internal environment

  2.1 Proprioceptors – receptors located in muscles, tendons and joint capsules that provide 

        informati on about the locati on of diff erent parts of the body

  2.2 Visceroreceptors – receptors located in the internal organs and vessels
