BIOL 1593 MODULE 12 EXAM
QUESTIONS AND ANSWERS
special senses - Correct Answers -smell, taste, vision, hearing, equilibrium
general senses - Correct Answers -both somatic and visceral senses
provide info about conditions within internal organs
sensation - Correct Answers -the process by which our sensory receptors and nervous
system receive and represent stimulus energies from our environment
conscious or unconsciousness awareness of internal or external stimuli
perception - Correct Answers -conscious awareness and interpretation of sensation
sensory receptors - Correct Answers -Specialized cells unique to each sense organ that
respond to a particular form of sensory stimulation.
have free nerve endings at dendrites of first-order sensory neurons, or separate cells
that synapse with first order sensory neurons
type of stimuli detected by sensory receptors - Correct Answers -mechanoreceptors
thermoreceptors
nociceptors
photoreceptors
chemoreceptors
osmoreceptors
free nerve endings - Correct Answers -bare dendrites associated with pain, thermal,
tickle, itch, and some touch sensations
encapsulated nerve endings - Correct Answers -dendrites enclosed in connective tissue
capsule for pressure, vibration, and some touch sensations
separate cells - Correct Answers -receptor cells that synapse with first-order sensory
neurons for special senses such as smell, taste, and vision
,mechanoreceptors - Correct Answers -detect mechanical stimuli; provide sensations of
touch, pressure, vibration, proprioception, and hearing and equilibrium; also monitor
stretching of blood vessels and internal organs
thermoreceptors - Correct Answers -detect changes in temperature
nociceptors - Correct Answers -respond to painful stimuli resulting from physical or
chemical damage to tissue
photoreceptors - Correct Answers -detect light on the retina of the eye
chemoreceptors - Correct Answers -detect chemicals in mouth (taste), nose (smell), and
body fluids
osmoreceptors - Correct Answers -sense osmotic pressure of body fluids
tactile sensations - Correct Answers -include touch, pressure, vibration, itch, and tickle
- corpuscles of touch
- hair root plexuses
- type I and II cutaneous mechanoreceptors
- lamellated corpuscles
- free nerve endings
crude touch - Correct Answers -the ability to perceive that something has contacted the
skin, even though its exact location, shape, size or texture cannot be determined
discriminative touch - Correct Answers -ability to recognize exactly what point of the
body is touched
-- meissner's corpuscles & hair root plexuses
rapidly adapting receptors
tactile/merkel discs & ruffini corpuscles - Correct Answers -type i & type ii cutaneous
mechanoreceptors
- slowly adapting touch receptors
name and describe the pain receptors - Correct Answers -nociceptors
branching ends of the dendrites of some neurons
free nerve endings
what is referred pain? - Correct Answers -pain sensation that the brain projects back to
some location other than where the pain originates
identify the specific locations where the receptors of the olfactory sense are found -
Correct Answers -found in the nasal epithelium in the superior region of the nasal cavity
on either side of the nasal septum
, pressure sensations - Correct Answers -generally result from stimulation of tactile
receptors in deeper tissues and are longer lasting and have less variation in intensity
than touch sensations; pressure is a sustained sensation that is felt over a larger area
than touch
receptors for pressure - Correct Answers -pacinian (type i mechanoreceptors)
lamellated (pacinican) corpuscles - adapt rapidly
vibration sensations - Correct Answers -result from rapidly repetitive sensory signals
from tactile receptors
receptors for vibration sensations are corpuscles of touch (low-frequency) and lamellate
corpuscles (high-frequency)
thermoreceptors - Correct Answers -free nerve endings
separate thermoreceptors respond to hot and cold stimuli
pain - Correct Answers -a vital sensation because it provides us with info about tissue-
damaging stimuli and signs that can be used for diagnosis of disease or injury
pain receptors - Correct Answers -nociceptors
free nerve endings located in nearly every body tissue
2 types of pain: fast & slow
referred pain - Correct Answers -pain that is felt in a location other than where the pain
originates
phantom pain - Correct Answers -sensation of pain without demonstrable physiologic or
pathologic substance; commonly observed after the amputation of a limb
- brain interprets nerve impulses that arise in remaining proximal portions of sensory
nerves as coming from a non-existent limb
which receptors are especially abundant in the fingertips, palms, and soles? - Correct
Answers -meissner corpuscles
type 1 cutaneous mechanoreceptor - Correct Answers -tactile or merkel disc
senses fine touch and pressure
*corpuscle of touch - meissner corpuscle* - senses fine touch, pressure, slow vibration
type 2 cutaneous mechanoreceptor - Correct Answers -ruffini corpuscle - senses crude
touch and stretching of skin
*hair root plexus* - senses crude touch
*lamellated (pacinian) corpuscle* - senses pressure and fast vibration
which visceral organ has the broadest area for referred pain? - Correct Answers -
kidneys
