Head tilt & rotation Mech.E Tongue Taste Molec. shape recog. Nose Odour Molec. shape recog. Skin, inner organs Touch, Vibration Mech.E Temp. Thermal.E Muscles Pain Chem. r'xn Stretch Mech.E Sensory Organs - stimuli detected by sensory organs comes from light, sound, odour, taste, or mech. contact from outside world - stimulatory info. goes from organs to brain via nerve impulses - nerve impulses = action pot.'s run by axons in sensory nerves Job = send info. to brain in way that it can rep. well about what is happening in environment.
