1

What is the concept of sensory perception

A process that involves receiving and interpreting environmental stimuli

2

What does sensory perception depend on

normal sensory receptors
intact reticular activation system
functional nervous pathways to the brain

3

Vertigo

feeling of rotation or imbalance while stationary. Can be chronic or acute

4

nystagmus

involuntary rapid eye movement

5

sensation

a physical feeling or perception in response to a stimuli

6

sensory reception

the process of receiving stimuli or data

7

perception

awareness and interpretation of a stimuli

8

presbycusis

age related hearing loss

9

ototoxicity

drugs that damage the ability to hear

10

paresthesia

sensation of prickling, tickling or numbness

11

kinesthesia

awareness of body parts

12

stereognosis

the ability to perceive and understand an object through touch, its size, shape and texture

13

visceral

large organs within the body

14

stimulus

an agent or act that stimulates a nerve receptor

15

receptor

a nerve cell that acts as a receptor by converting the stimulus to an impulse

16

impulse conduction

act of an impulse traveling along a nerve pathway to the spinal cord or directly to the brain

17

awareness

ability to perceive environmental stimuli and body reactions and then respond

18

myopia

near sighted

19

hyperopia

far sighted

20

cataracts

breakdown in protein in lens. results in lens not being able to change shape to focus

21

glaucoma

optic neuropathy w/ gradual loss of peripheral vision

22

age related macular degeneration

loss of central vision due to retina damage

23

peripheral neuropathy

occurs when trauma or disease processes interfere with innervation of peripheral nerves

24

Risk factors for impaired sensory perception

age
chronic disease
eye/ear trauma
ototoxic drugs
environmental/occupational exposure

25

physiological consequences of impaired sensory perception

potential safety issue
decreased ability to perform ADLs

26

define amblyopia

lazy eye

27

conductive hearing loss
most common cause

anything that disrupts the transmission of sound from external ear to inner ear.
most common cause is obstruction of the external ear canal.

28

sensorineural hearing loss

disorders that affect the inner ear, the auditory nerve or the auditory pathways of the bran. soundwaves are transmitted to inner ear but damaged receptors are unable to receive and interpret stimuli

29

screening periods across lifespan for hearing

Newborns:before they leave hospital
preschool/school age: periodically at well child visits
adults: every 10 years
>50: every 3 years

30

screening periods across lifespan for vision

3-5 years: at least once
Exam at 40
40-54: every 2-4 years
55-65: every 1-3 years
>65: every 1-2 years
