Document Summary
Sensory information about the environment is received by sensory receptors (taste buds, rods and cones in eyes, etc. ) Smells, taste, light, sound waves, pressure on skin, etc. Perception is how the senses are organized and interpreted by the brain into a meaningful experience. Becoming less sensitive to sensory input (not continuing to perceive the smell, sound, etc. ) Absorbs light, processes images, sends visual info to the brain. Rods detect brightness of light, help with peripheral vision (see in low light) Cones allow color vision and visual activity. Impulses are sent to the optic nerve (connects retina to the brain) Then travel though the optic chiasm -> thalamus -> occipital lobe. Sounds waves enter through the outer ear and are funneled to the eardrum. Eardrum vibrations cause movement of tiny bones in the middle ear, which turns into waves of pressure. Cochlea: fluid-filled part of the inner ear that contains receptors for hearing.
