Document Summary
It is multilayered(from innermost layer out) cones and rods (sensory receptors in retina) bipolar cells that connect to ganglion cells whose axons bunch together to form the optic nerve the optic nerve is the nerve that leaves the eye and carries information to the brain blind spot where the optic nerve leaves to go to the brain there are no receptors, therefore it is a blind spot fovea the center of the retina made entirely of cones responsible for fine details in vision. Frequency to action potential per second is 1:1 i. e. 20 hz= 20 action potentials in one second however, cilia can only fire 1000 action potentials per second we can detect sound waves up to 20,000 hz this problem is solved by the volley principle when sound waves with a high frequency are detected, other groups of hair cells pitch in & coordinate to produce the correct number of firing.
