sensory fanction and it's model.
Receptor cells
specific sensary cells that are sensitive to type of stimaks, which crases change in the resting starte and creats receptor potential.
Receptor potential
Lis a local change in the membrane potential of the Receptor cell, it amplitude is depended on the stimalis intensity (Amplitude)
*in case of a weak stimulas
The relative change of the receptor potential
if it's greater than the strong stimulas.
dynamic compression.
Ithis enables us to perceive stimuli across several ages of orders of magnitude withas single ogan
The relative change of the receptor potential
if its smaller than the strong stimulus.
dynamic expansion.
The sensory nerve cell, which is connected to the receptor cell, converts the receptor potential into the tran of uniform (constant amplitate) action potentiM
frequency-coding
The strength of sensation corresponds to the Simpency of the action potential.
