Ch. 23 Neuro Flashcards
Parietal lobe is responsible for
it assists in tactile sensations to
recognition of _ _ and awareness of body position also called
processing sensory data as it is received.
temperature, pressure, pain, size, shape, texture, and two point discrimination
also visual, taste, smell, and hearing sensations.
body parts, proprioception
occipital lobe =
vision
temporal lobe=
reception and interpretation of speech is located in
hippocampi responsible for
responsible for the perception and interpretation of sounds and determination of their source.
also taste, smell, and balance
Wernicke area
memory
basal ganglia refine
motor movements
cerebellum aids in
voluntary movement, have ipsilateral same side control of the body
motor or efferent fibers of anterior root carry impulses from the spinal cord to the _ and _ of the body
afferent of posterior root carry impulses from the sensory receptors of the body to the _ _ and then to the brain for interpretation by cerebral sensory cortex.
muscles and glands
spinal cord
Infants/children major portion of brain growth occurs in first year of life alone with _ of the brain and nervous system
primitive reflexes present at birth are:
motor maturation proceeds in a _ direction
myelinization
Moro, stepping, plantar and palmar grasp.
cephalocaudal (motor control of head and neck occur first then trunk and extremities)
Elderly brain size _ as well as cerebral neurons
taste smell and _
_ _ _ may be diminished from velocity of nerve impulse conduction declining.
_ disturbances also occur
decreases
vision are diminished
deep tendon reflex
sleep
Automatism means
eyelid fluttering, chewing, lip smacking, swallowing during seizures.
when assessing olfactory nerve this is only done when there is a problem with odors this is done by closing one nostril and alternating odors.
Inflammation, allergic rhinitis, _ may interfere with odor,
with _ this diminishes as well
Anosmia is when
smoking , age
there is a loss in sense of smell or inability to discriminate odors.
the _ cranial nerve is first to lose function in presence of increased intracranial pressure
6th (abducens)
Romberg test is done to assess
if positive this means
balance
cerebellar ataxia, vestibular dysfunction, or sensory loss..
loss of sensation can mean
if lose of sensory modalities when moving big toe up and down can mean
spinal stract, brainstem, or cerebral lesions.
peripheral neuropathy or if symmetric sensory loss indicates polyneuropathy
tactile agnosia is the inability to
recognize objects by touch and can suggest a parietal lobe lesion.
graphesthesia
extinction phenomenon is when
draw a letter, number or shape on palm of patients hand while eyes closed
simultaneously touch two areas on each side of the body with sharp edge ask patient to tell where touched and number of stimuli.
