Receptors - Pacinian Corpuscles (AQA A-Level Biology): Flashcards

Detection of stimuli by receptors

Brain processing & interpreting detected information

Mechanical pressure only

Convert one form of energy into another

Mechanical energy (pressure) to electrical (nerve impulses)

Electrical change created by transduction in receptor

Fingertips, soles of feet, genitalia, joints/ligaments/tendons

Concentric layers of connective tissue with viscous gel between

Stretch-mediated $Na^+$ channels closed, resting potential maintained

$Na^+$ enters as channels widen, membrane depolarises
