The body has the following senses:
The eye receives and focuses light and converts this energy into nerve impulses that are sent to the brain. The nerve impulses originate from the retina. Visual receptors in the retina called rods can work in low intensity light. They have no color function. The visual receptors called cones operate in high intensity light and do receive colors.
The ear's functions include hearing, static equilibrium (balance while standing still), and dynamic equilibrium (balance when moving). The outer and middle parts of the ear are responsible for sound gathering and the transmission of sound. The inner ear has the nerve endings for hearing and equilibrium.
