QuestionAnswer
raw form in which these receptors send information to the brain sensation
the way the brain interprets the information perception
respond to changers in the concentration of chemical substances chemoreceptors
respond to numerous stimuli and tissue damage pain receptors
sensitive to temperature changes thermoreceptors
respond to light photoreceptors
associated with the changes of body surfaces(touch, pressure, pain, & temperature) extroreceptive senses
changes with viscera(blood pressure, pH, meals) visceroreceptive senses
changes in muscles and tendons and in body position proreoreceptive senses
(simplest) lie between epithelial cells; responsible for the sensation of itching (temperature & pain) free nerve endings
found on lips, fingertips, palms; provides fine touch meissner's corpuscles
(common in deep dermal tissue) detect heavier pressure pacinian corpuscles
body has warm and cold receptors; allows quick adaptation temperature senses
sharp pain; lasts for a few seconds; leaves as soon as stimulus leaves acute pain
dull, aching pain; cannot pin point; localized pain chronic pain
oxygen defficiency hypoxia
blood defficiency ischemia
tells you where pain is coming from projection
pain fomes from another part of the body other than the part being stimulated (example: heart attack) referred pain
blocks substance p which causes pain impulses enkephalins
stimulates other nuerons to release chemicals to fight pain serotonin
blocks substance p; produced by pituitary glands endorphins
bipolar nueron; has microvili, receptor proteins, 12 million cells; 500 different types of chemoreceptoprs olfactory receptors
are molecules such as proteins and glycoreceptors located on the cell membrane membrane receptors
strongest evoker of memory smell
splits impulses down the olfactory tract olfactory bulb
sends impulses to portions of the limbic system olfactory tract
main interpreting areas for the olfactory impulses cerebral cortex
adapt quickly to smell sensations; only nuerons to be replaced on a regular basis and only to come in contact with the external factors olfactory receptors
percent of taste sensation comes from the sense of smell 75
sensory organs for taste; located on cheeks, roof of mouth, tongue, and pharynx taste buds
have microvilli and are modified epithelial cells (not nuerons) gustatory cells
bumps on tongue that has one taste bud taste pore
microvilli on ends of taste cells taste hairs
carbs (tip of tongue) sweet
acidic (lateral of tongue) sour
ionized inorganic salts (widespread) salty
bases and alkaloids, & poisons (back of tongue) bitter
