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
Sensory processing disorder
Difficulty in the way the brain takes in, organizers, and uses sensory information, causing a person to have problems interacting effectively in the every day environment
Sensory reception
The process of receiving data about the internal or external environment through the senses
Stereognosis
The sense that perceives the solitary solitary 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
Visual
Pertaining to sight
Special Senses
Visual
Auditory
Olfactory
Gustatory
Somatic senses
Tactile
Nerve endings
Characteristics of normal vision
Visual acuity at near 20/20, full field of vision, tri color vision
Characteristics of normal hearing
Acuity of sounds at 0 to 25 dB
Characteristics of normal taste
Ability to discriminate sour, salty, sweet, and bitter
Characteristics of a normal smell
Primary odors musky, floral, peppermint, pungent, putrid, ethereal, camphoraceous
Characteristics of normal touch
Pressure, vibration, tickling, pain, position, temperature
Myopia
Nearsightedness
Hyperopia
Farsightedness
Hypogeusia
Decrease in taste, caused by decreased testosterone
Hyposmia
Decrease in smell
Achromatopsia
Can only see and shades of gray
Conductive hearing loss
Caused by Creamun and infection
Causes of tinnitus
Medication ototoxicy
Aspirin
Reducing sodium can help
Diabetes and high blood pressure can make it worse
Romberg test
Test for vertigo
Patient stands with their feet together and shoes off, arms are held at the side, patient must stand with eyes open and then closed and try to maintain balance
Sensorineural hearing loss
Defect in the afferent nerve
Cochlear implants are the treatment
Cochlear implants do not cure deafness
