Structures Cerebrum Cortex Frontal lobe Temporal lobe Parietal lobe Occipital lobe Thalamus Hypothalamus Cerebellum Brainstem Midbrain Medulla Meninges Ventricles
FunctionsWhat are the functions of…
Cerebrum: Largest part of brain
Cortex: Outer layer of cerebrum; controls
most conscious processesFrontal Lobe:
Emotional expression, Broca’s area (expressive language) (Continued)
FunctionsWhat are the functions of…
Temporal lobe:
Hearing, taste, smell, memory, Wernike’s (language comprehension)
(Continued)
FunctionsWhat are the functions of…
Parietal: Sensory input
Occipital lobe: Vision and spatial relationships
(Continued)
FunctionsWhat are the functions of…
Thalamus: Clusters multiple sensory stimuli
Hypothalamus: Controls autonomic nervous system
and pituitary glandCerebellum:
Coordination, equilibrium(Continued)
FunctionsWhat are the functions of…
Brainstem: Involuntary survival behaviors;
includes midbrain, medulla and pons
Midbrain: Visual, auditory, pupils, and eye
movements(Continued)
FunctionsWhat are the functions of…
Medulla: Regulates heart, respiratory rates,
B/P, and protective reflexesPons:
Helps with respiratory function, facial sensation and movement
(Continued)
FunctionsWhat are the functions of…
Meninges: 3 layers (pia, arachnoid, dura);
protect brain and spinal cordVentricles:
4 cavities; capillaries produce and reabsorb CSF

DevelopmentalVariationsWhat developmental variations of the
neurologic/sensory system might you seen with:
ChildrenPregnant clientsOlder adults
Cultural Variations
What cultural variations of the neurologic/sensory system might be seen with:
African Americans Irish Native Americans
HistoryWhat can the history tell you about the neurologic/sensory system?
Biographical data Current health status Past health history Family history Review of systems Psychosocial history
SymptomsWhat symptoms would signal a problem with the neurologic/sensory system? Headache Mental status change Dizziness, vertigo, syncope Numbness or loss of sensation Deficits of the 5 senses Seizures
Physical AssessmentApproach: inspection, palpation, and
auscultation Position: sittingTools: stethoscope, B/P cuff, penlight,
gloves, cotton, sharp object, coin, fragrance, sweet and sour substance, tongue blade, test tubes, reflex hammer, ophthalmoscope
General Survey and head-to-toe scan
Cerebral FunctionMental Status Behavior Level of consciousness: time, place,
person Glasgow Coma Scale Memory: recent, remote, four unrelated
words test Mathematical ability Thought process Judgement General knowledge Communication
Sensory FunctionSuperficial sensations: Light touch Pain Temperature
Deep sensations: Vibratory sensations Kinesthetics
