Overview of Sensation and Meissner's Corpuscle

What is the basic idea behind how our skin helps us perceive our environment?

• It has mechanoreceptors that perceive forces

• It generates heat to sense the environment

• It absorbs nutrients from the environment

• It produces light to sense the environment
