CH 17 - Assessing the Neurological System Flashcards
Cerebral Cortex Lobes (4)
Frontal
- Responsible for reasoning, abstract thoughts, concentration
- Broca’s area: expressive aspects of spoken and written language
Parietal
- Responsible for the ability to interpret sensations from anywhere on or within the body
Temporal
- Help you use your senses to understand and respond
- Wernicke’s area: Responsible for speech comprehension
Occipital
- Process visual signals
Cerebellum
- Links sensory to motion
- Responsible for coordination, balance, speech, and senses
Brainstem
3 Parts: Medulla oblongata, Pons, Midbrain
- Controls involundary behaviors
- Transmit impulses from spinal cord to the brain
Cranial Nerve Functions (Sensory, Motor, or Both)
Some - Olfactory
Say - Optic
Marry - Oculomotor
Money - Trochlear
But - Trigeminal
My - Abducens
Brother - Facial
Says - Vestibulocochlear
Big - Glossopharyngeal
Brains - Vagus
Matter - Accessory
Most - Hypoglossal
Stroke Symptoms
BE FAST
Balance - loss of balance, headache or dizziness
Eyes - blurredd vision
Face - one side of the face drooping
Arms - arm/leg weakness
Speech - speech difficulty
Time - time to call for ambulance immediately
Changes in Speech (Dysphasia, Aphasia, Receptive Aphasia, Expressive Aphasia)
Dysphasia: Partial impairment of language and speech impacting the ability to communicate
Aphasia: complete impairment of comprehension and expression in the verbal, written, and signed modalities
Receptive aphasia: Damage to Wernicke’s area of the brain; unable to understand language in written or spoken form.
Expressive aphasia: Caused by damage to the Broca’s area; unable to communicate language in written or spoken form
Respiratory (Dyspnea, Hypoxia)
Dyspnea: shortness of breath
Hypoxia: lack of oxygen supply to the brain, can result in changes to mental status
Cerebral Vascular Accident
Ischemic Stroke: occlusion of oxygenated blood flow to the brain caused by a clot or occluded artery in the brain
Hemorrhagic Stroke: bleeding from an artery in the brain
