Document Summary
Receptors that detect stimuli from inside the body interceptors. Detect stimuli from outside the body extroceptors. Pain and pressure: hearing (special sense, balance (special sense) Special because the receptors are located in an organs specialized for that particular sense. Chemoreceptors: taste (special, smell (special, ph electromagnetic receptors, vision (special, electromagnetic energy such as light and heat. 2. 24. 15 because senses are limited, there are things we do not perceive such as electromagnetic field of the earth and infrared light. In tendons: baroreceptors monitor blood pressure carotid sinus blood to the brain aortic arch near the heart. Sound detection by mechanocreptors aquatic vs terrestrial sound: otoliths fish hearing structures denser than water. 2. 24. 15 can allow them to detect sound fish lateral line system senses pressures and vibrations: human ears outer and middle (malleolus, incus, stapes) Convert sound waves into motion of solid structures and transfers to the liquid of the inner ear inner ear (semicircular canals, utricle, saccule) sound wave receptors.
