Classification of Sensory Receptors Flashcards
Give the Location, Stimulus Type and Body Location for Free Nerve Endings
Location: Exteroreceptors, interoreceptors
Stimulus Type: Nociceptors (pain), thermoreceptors (temperature), & mechanoreceptors (pressure)
Body Location: Most body tissues; abundant in epithelia & connective tissues.
