Senses Chpt 10
Senses Chptr 10
| 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 |
| Corneal transplant | readily accessible, easy to remove, avascular (no bleeding)less rejection, long term success (one of the 1st organs xplant) |
| 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 |
| name 4 different taste receptors and where they are located on the tongue | Salty (tip of tongue) Sweet (just behind tip of tongue), Sour (sides of middle of tongue) Bitter (back of tongue left to right) |
| Bony Socket (bony orbit)does what for the eye? | Protects it |
| 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) |
| Lacrimal Gland does what | produces tears |
| 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) |
| Refraction | the bending of light rays |
| accomodation | adjustment to the vision of the eye |
| Auditory | sense of hearing |
| AD | Right Ear |
| AS | Left Ear |
| AU | both ears |
| External ear also known as | Auricle or Pinna |
| Fleshy part of ear | Auricle or Pinna |
| Otitus Externa | Swimmer's Ear |
| Tinitus | ringing of the ears |
| Otinius Media | middle ear infection |
| Tympanic Membrane | think membrane middle ear, vibrates with stimulus |
| 3 bones inside ear | Malleus, Staples, Incus |
| Eustachian Tube | aka Auditory tube; connects ears to throat |
| Bony Labryrinth - itis | infection of the inner ear |
| Cochlea | snail like coil inner ear (bony labyrinth) functions in hearing |
| cerumen | ear wax |
| Meniere's disease | lifelong chronic inner ear disease, recurring attachks, dizziness, loss, tinnitis |
| Tinnitus | ringing or buzzing in the ears |
| Vertigo | Feeling of dizziness, loss of balance, room spinning |
| Blepharitis | inflation of the edges of the eyelid |
| Glaucoma | increased pressure in the eye, if untreated blindness |
| Macular Degeneration | breakdown of cells in macula lutea, central vision (older people) |
| Nyctalopia | night blindness |
| Otosclerosis | formation of bony tissue around oval window immobilizing stapes (ear) results in deafness |
| Presbycusis | impairment of hearing from aging |
| Presbyopia | impairment of vision from againg |
| Sensorineural deafness | noise related ear damage to the cochlea (pathway to cortex cerebelum) |
| Tympanitis | inflammation of the tympanic membrane |
