Solutions.
What are the two components of the sensory process? correct answers sensory reception and
perception
What is sensory reception? correct answers process of receiving stimuli or data
(Can be either external or internal to the body)
External Stimuli are? correct answers visual (sight), auditory (hearing), olfactory (smell), tactile
(touch). gustatory (taste - can be internal as well)
What are types of internal stimuli? correct answers Kinesthetic or visceral
Whats kinesthetic? correct answers awareness of position and movement of body parts
ex. person walking knows which leg is forward
What is stereognosis? correct answers ability to perceive and understand an object through touch
by its size, shape, and texture
What is visceral? correct answers Any large organ in the body
(may produce stimuli that make a person aware such as full stomach)
What is sensory perception? correct answers Conscious organization and translation of the data
or stimuli into meaningful information
For an individual to be aware of the surroundings they must have these four aspects of the
sensory process: correct answers 1. stimulus - agent or act that stimulates a nerve receptor
2. receptor - nerve cell acts as a receptor by converting stimulus to a nerve impulse. Most are
specific - sensitive to only one type of stimulus
3. impulse conduction - impulse travels along nerve pathways either to spinal cord or brain.
4. Perception - awareness or interpretation of stimuli, takes place in the brain - were the cells
interpret the nature and quality of the sensory stimuli. (Affected by LOC)
What is presbyopia? correct answers inability to focus up close, part of the aging process (40-50)

stimulation.
Medications (narcotic, antidepressant, sedative)
Lifestyle and personality
What is ototoxic? Examples? correct answers injuring the auditory canal and causing hearing
loss that might be irreversible (ex. furosemide, aspirin, certain drugs for chemo, amino
glycosides)
What is sensory deprivation? correct answers decrease or lack of meaningful stimuli
- experiences alterations in perception, cognition, and emotion
What is sensory overload? correct answers person is unable to process or manage the amount or
intensity of sensory stimuli
What is s sensory deficit? correct answers impaired reception, perception or both of one or more
senses (When loss is gradual individuals often develop behaviors to compensate for loss - such
as hearing loss in right ear they might turn there left ear to the noise)
*Risk for sensory deprivation or overload
