What can we hear (loudness)- 0 to 140 decibels. Sound waves pass through the auditory canal to the ear drum. Normally thought of as the detection of pressure against the skin. Sense of touch is a mix of at least 4 distinct skin senses. Sense temperature changes at or near our skin. Provide input to keep our body"s temperature regulation at 98. 6 f. Pain is the sensation that warns us that damage to our bodies is occurring. There is not a specific type of stimulus that triggers pain. Nociceptors: sensory receptors that detect hurtful temperature pressure. Smell can provide us important information food choices tracking recognition. Chemical molecules reach receptors at the top of the nose and then these receptors send messages to the brain. How good are humans at recognizing smells.
