Senses Chapter 9
Quiz 3
| Question | Answer |
|---|---|
| Meissner | Fine tough and low frequency vibration |
| Bulbous (ruffini) corpuscle | Touch and pressure |
| Free nerve ending | Naked nerve ending. Pain, crude touch, temperature, itch, tickle |
| Encapsulated nerve ending | Caped |
| Lamellar (pacini) corpuscle | Pressure and high frequency vibration |
| Bullboid corpuscle (Krause and bulbs) | Touch |
| Golgi tendon organs & Muscle spindles | Proprioception |
| Proprioceptors | Postion of muscles |
| Mechanoreceptors | Movement of body |
| Photoreceptors | Light; eye |
| Chemoreceptors | Chemical; internal environment |
| Pain receptor | Injury |
| Thermoreceptor | Temperature change |
| Function of nerves | Detect particular stimulus, convert stimulus to nerve impulse, perceived as sensation in CNS |
| Sclera | White of eye, tough to protect |
| Choroid | Front part made of ciliary muscle and iris |
| Pupil | An actual hole in eye |
| Ciliary muscle | Contract or constrict pupil |
| Retina | Night and day vision |
| Retina; Rods | Dark, at night |
| Retina; Cones | Light and color, day |
| Conjunctiva | Covers sclera, lines eye ball or eyelid |
| Conjunctivitis | Pink eye |
| Lens | Takes light rays and focuses on retina |
| Aqueous humor | Water like fluid, forms in front of lens, anterior lens |
| Vitreous humor | Posterior of lens, "jelly-like" liquid. Shape eyeball |
| Cataracts | Lens of eye gets hard and loses elasticity. Looks cloudy, milky, a progressive progress |
| Glaucoma | Increase pressure in eye. If drainage is blocked and can lead to blindness. Aqueous humor |
| Myopia | Nearsightedness |
| Hyperopia | Farsightedness |
| 20/20 vision | The normal vision |
| Presbyopia | "old sightedness". Farsightedness aka hyperopia, ciliary muscles loses elasticity |
| Ear receptors | Mechanioreceptor |
| ear | Balance, equilibrium |
| Ear ossicles | Malleus hammer, incus pound on, stapes straps |
| External ear | Auricle (pinna) top of ear |
| Ceremonious gland | secrete wax |
| Tympanic membrane | ear drum |
| Tympanic membrane | Vibrates to hear |
| Auditory tube | Station tube, connect middle ear to throat |
| Ottis media | Infection of the middle ear |
| Cristae ampularis | Receptors for balance in semicircular canal |
| Specialized hair cells | Stimulate movement of sound |
| Corti | Specialized for hearing |
| Bone deafness | Disturbance in bones |
| Nerve deafness | Auditory or acoustic nerve get "tire" don't work as well |
| Presbycuses | Old age, loss of hearing |
| Chemoreceptors | Found on taste buds |
| Primary taste sensations | Sweet, sour, bitter, salty |
| Metallic & Unami(meat) | New sense |
| Gustatory and olfactory | sends or creates taste sensations |
| Gustatory | Taste |
| Olfactory | Nose |
| Smell (Olfactory) receptors | Chemoreceptors upper part of nasal cavity |
| In order to smell | The smell has to be dissolved |
| Association of smell | Stored |
