Question | Answer |
Mechanoreceptors | Touch & pressure are from free nerve endings deform or displace tissues |
Meissner's Corpuscles | Light touch pressure sensor |
Pacini Corpuscles | Heavy touch pressure sensor |
Proprioception | Sense of position or orientation of the body, Rate of movement one body part to another |
Thermorceptors | Located immediately under the skin, most on the lips, least on the broad surfaces body trunk |
More cold or hot receptors | 10x more cold receptors than hot |
location of most thermoreceptors | on the lips |
Nociceptors | Pain free nerve endings stimulated by tissue damage, skin & tissues of the internal organs, they don't adapt & will continue to make you feel pain even when stimulus stops |
Gustatory | Sense of taste a chemoreceptor, Thalmus controlled to parietal lobe |
parts of Gustatory (taste) | Taste Buds, Papillae, taste pore, taste hairs (microvilli) |
2 types of Gustatory nerves | facial nerve and glossapharyngeal nerve |
Name general senses | Touch, Pressure, Temperature, Pain, Proprioception (position/orientation) |
Chemoreceptor | Chemical (chemical changes in taste & smell) |
Mechanoreceptors | pressure (bending/deforming cell/tissue) in joints, hearing, equilibrium) |
nociceptors | pain receptor (tissue damage) |
thermoreptors | temperature (heat & cold) |
Photoreceptors | light energy (vision) |
receptor detector (chain/steps) | Stimulus-receptor dectection-CNS to interpret |
Odors | pleasant/unpleasant, unnoticed after a time, can result in nausea |
cold adaptation | cold/hot abruptly then the receptors adapt (ex cold water in pool) |
Headache | referred surfaces of the head, or menignes & blood vessels, sinuses, eyes |
Bitter Taste | highest degree of sensitivity, reject it, poisons and toxins |
Blinking | eye blinks 6-30 times/min, stimulates lacrimal glands to secrete tears to lubricate across the eye |

Pupils | Dialate during problem solving, or if subj is appealing, reflexes reflecting interest or emotional state, Restrict if boring repulsive |
Detaached Retina | sensory portion breaks away, Trauma or eye disorder, resulting in distored vision eventual blindness, reattach via laser Sx |
Color Blindness | absence or def in cones, common red/green, inherited > males |
Ruptured Eardrum | perforated by shock waves from explosion, scuba, trauma, acute middle ear infections, acute pain, noise, hearing impairment |
Motion Sickness | nausea/vomiting, resulting repetitive/ excessive stimulation of equilibrium receptors some are more suseptible than others |

Accessory Structures do what for the eye? | protect and move the eyes |
Eye brow function | keeps perspiration out of the eye, it can cause irritation |
Eyelids function | open and close the eye, keep foreign objects out |
Conjuctiva | keeps the eye from drying out, thin mucous membrane that lines the eyelid,covers most of the eye except the cornea |
Muscles associated with the eyelid | Orbicularis Oculi, (closes the eye) & Lavator Palpebrae Superioris (opens the eye) |
Eyelash function | helps trap foreign particicles |
Sebaceous glands | associated with eyelashes) secrete oily fluid that lubricates the region (inflamation is a stye) |

Sclera is what | whites of the eyes (= 5/6 of the eye) |
Cornea | "window of the eye" transparent layer outside of the eye |
Choroid | vascular brown pigmented layer posterior of eye |
Iris | colored part of the eye |
pupil | doughnut shaped diapharagm (lets in/out light) dialates and constricts |
Retina | "visual part of the eye" innermost layer of the eye, posterior, contains rods & cones |
Optic Nerve | Visual impulses to the brain |
Rods | low light vision (night vision) |
Cones | color vision |
Type of sight chart most used | Snellen |
Color Chart | Ishihara |
OD | Right Eye |
OS | Left Eye |
OU | both eyes |
Aqueous Humor | liquid maintains shape of eye & provides nutrients (front of eye shape, eye pressure) |
Vitreous Humor | presses retina to the wall of the eye, supports internal shape, provides nutrients (eyeball shape) |
