Neuro Flashcards
Agnosia
loss of ability to recognize objects through a particular sensory system; may be visual, auditory, or tactile
ataxia
inability to coordinate muscle movements
aphasia
efers to loss of the ability to express oneself or to understand language
Frontal lobe
largest lobe concentratioin abstract thought info storage memory
Temporal lobe
auditory receptive area
plays a role in memory of sound and f understanding language and music
parietal lobe
predominately sensory lobe
analyzes and relays sensory info to thalamus and other cortical areas
spatial relationships
occipital lobe
visual interpretation and memory
Cranial I
Olfactory
sense of smell
C II
optic
visual acuity and visual fields
C III
oculomotor
muscle that move the eye and lid
pupillary constriction
lens accommodation
C IV
trochlear
muscles that move the eyes
C V
trigeminal
facial sensation
corneal reflex
masticationi
C VI
abducens
muscles that move the eye
C VII
symmetry of facial expression muscle movement in upper and lower face salivation and tearing taste sensation in the ear
C VIII
acoustic
hearing and equilibrium
C IX
glossopharyngeal taste sensation in pharynx and tongue pharyngeal muscles swallowing
C X
Vagus
muscles of pharynx, larynx, and soft palate
sensation in external ear, pharynx, larynx, thoracic and abdominal viscera
parasympathetic innervation of thoracic and abdominal organs
C XI
Spinal accessory
sternocleidomastoid and trapezius muscle
C XII
hypoglossal
movement of tongue
structural and motor changes in geriatric patients
Structural and motor changes related to aging that may be assessed in geriatric patients include decreased or absent deep tendon reflexes.
Pupillary responses are reduced or may not appear at all in the presence of cataracts.
There is an overall slowing of autonomic nervous system responses.
Strength and agility are diminished and reaction and movement times are decreased.
Where is CSF produced?
ventricles
the fourth ventricle supplies CSF to where?
subarachnoid space and down the spinal cord on the dorsal surface
arachnoid villus
area in the brain where CSF is absorbed
upper motor neuron lesions
loss of voluntary control Inc. muscle tone muscle spasticity no muscle atrophy hyperactive and abnormal reflexes
lower motor neuron lesions
loss of voluntary movement dec. muscle tone flaccid muscle paralysis muscle atrophy absent or dec. reflexes
