Document Summary
Sensation is how the sense organs respond and detect external stimulus energy and how those responses are transmitted to the brain. Translation process when sensory receptors detect the environmental stimulus and convert it into the neural signal. A receptor cell is a specialized neuron: name the receptors for each of the 5 senses. Bottom up processing us when the sense receptors detect the environmental stimulus and translate it into the neural signal. The neural signal then travels to the brain for construction and further processing. Hue is the dimension of color determined by the wavelength of the light. The cornea is the transparent tissue where light enters the eye. The iris is a muscle that expands and retracts to change the size of the pupil for light. The lens focuses the light rays on the retina. Rods are activated by low lights levels and don"t support color vision. The optic nerve transmits visual information from the retina to the brain.
