Ch 44 Sensory Functioning 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 are is at risk for a change in the amount, pattern, our 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 movement and position of the body, especially its limbs, independent of vision
Reticular activating system RAS
Network of neurons in the core of the brain stem, with ascending and descending tracts to other areas of the brain that monitor and regulate incoming sensory stimuli and level of arousal
RAS is highly selective
It is located between the nerve centers in the medulla oblongata and the brain stem
It is responsible for bringing together information from the sense organs
If destroyed, results in coma
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
Conscious process of selecting, organizing, and interpreting data from the senses into meaningful information sensory/perceptual altercation disturbance in the body’s ability to receive a process data from its internal or external environment
Sensory poverty
Condition that results when one learns about the world without experiencing it up close, right here, right now
