Classification of receptors-Based on adaptation
The receptors of cells are divided into the following based on adaptation:
1. Rapidly Adapting Receptors (RAR’s)
o Adapts quickly to stimulus
o Ex: Corpuscles – Meissner’s & Pacinian Corpuscles
2. Slowly Adapting Receptors (SAR’s)
o Adapts slowly to stimulus
o Ex: Merkel’s Cells, Ruffini’s endings, Free nerve endings.
