Sensory Perceptions Flashcards
Adaptation
adjustment of living with other living things and environmental conditions
Arousal
condition in which the cortical area of the brain receives and responds appropriately to stimuli
auditory
pertaining to hearing
disturbed sensory perception
a state in which the individual or group experiences or is at risk for a change in the amount, pattern, or interpretation of incoming stimuli
gustatory
pertaining to taste
kinesthesia
awareness of positioning of body parts and body movement
olfactory
pertaining to smell
proprioception
description of the sense, usually at a subconscious level, of the movements and position of the body, especially its limbs, independent of vision
reticular activating system (RAS)
network of neurons in the core of the brainstem, with ascending and descending tracts to other areas of the brain that monitor and regulate incoming sensory stimuli and level of arousal, extends from hypothalmus to medulla
sensoristasis
arousal state of the reticular activating system; general drive state
sensory deficit
impaired or absent functioning of one or more senses
sensory deprivation
condition resulting from decreased sensory input or input that is monotonous, unpatterned, or meaningless
sensory overload
condition resulting from excessive sensory input to which the brain is unable to meaningfully respond
sensory perception
a state in which the individual or group experiences or is at risk for a change in the amount, pattern, or interpretation of incoming stimuli
sensory poverty
condition that results when one learns about the world without experiencing it up close, right here, right now
sensory reception
the process of receiving data about the internal or external environment through the senses
stereognosis
the sense that perceives the solidity of objects, their size, shape, and texture
stimulus
agent, act, or other influence capable of initiating a response by the nervous system
tactile
pertaining to touch
visceral
pertaining to inner organs
Delirium
a conscious state, Disorientation, restlessness, confusion, hallucinations, agitation, alternating with other conscious states
Dementia
a conscious state, Difficulties with spatial orientation, memory, language; changes in personality
Confusion
a conscious state, Reduced awareness, easily distracted, easily startled by sensory stimuli, alternates between drowsiness and excitability; resembles minor form of delirium state
Normal consciousness
a conscious state, Aware of self and external environment, well-oriented, responsive
Somnolence
a conscious state, Extreme drowsiness, but will respond normally to stimuli
Minimally conscious states
a conscious state, Part consciousness; sleep–wake cycles present; some motor function, including automatic movements; inconsistently follows commands
Locked-in syndrome
a conscious state, Full consciousness; sleep–wake cycles present; quadriplegic, auditory and visual function preserved; emotion preserved
Asleep
an unconscious state, Can be aroused by normal stimuli (light touch, sound, and the like)
Stupor
an unconscious state, Can be aroused by extreme and/or repeated stimuli
Coma
an unconscious state, Cannot be aroused and does not respond to stimuli (coma states can be further subdivided according to the effect on reflex responses to stimuli; see Glasgow Coma Scale
Vegetative State
An unconscious state, Cannot be aroused. Sleep–wake cycles, postures or withdraws to noxious stimuli, occasional nonpurposeful movement, random smiling or grimacing.
