Neurological Assessment Flashcards
Nervous System
Divided into two regions
Central Nervous System (CNS)
Peripheral Nervous System (PNS)
CNS - Brain
Control center of body
Covered and protected by scalp, skull, and meninges
Blood brain barrier
CNS - BRAIN PARTS:
Cerebrum
Diencephalon
Cerebellum
Brain Stem
right and left hemispheres, frontal, parietal, occipital & temporal lobes
Cerebrum
(thalamus and hypothalamus) body temp, sleep
Diencephalon
position sense, posture & equilibrium/balance
Cerebellum
(medulla oblongata, pons & midbrain) resp. & cardiac regulation, sneezing
Brain Stem
Lobes of the Cerebrum
Frontal
Parietal
Temporal
Occipital
somatic sensory center
Frontal
higher intellect, speech production, personality, behavior, emotions, voluntary movement
Parietal
hearing, memory, speech perception and translation
Temporal
vision
Occipital
CNS – Spinal Cord: ECGM
Extends from medulla to the level of the first lumbar vertebra
Cord protected by vertebra, meninges and cerebral spinal fluid
Gray matter is on the inside and white matter on the outside
Mediates deep tendon reflexes
Spinal Roots
Cervical, thoracic, lumbar nerves
posterior roots?
sensory
anterior roots?
motor
damage to posterior roots?
loss of sensation
damage to anterior roots?
flaccid paralysis
Peripheral Nervous System (PNS): TEX
-The PNS links CNS with the rest of the body
-External environmental information received and transmitted via PNS
-Cold, wet, hot, pain
Spinal Nerves: CTLSC
Cervical 8 pairs C1-C8
Thoracic 12 pairs T1-T12
Lumbar 5 pairs L1-L5
Sacral 5 pairs S1-S5
Coccygeal 1 pair Coccyx
Reflex
- Rapid involuntary predictable motor response to a stimulus. Reflex arc, is not dependent on the brain.
Skeletal muscle contraction
Somatic
Cardiac, smooth muscle and glands
Autonomic
Assessment
- Three basic types of neurologic examination
- Check Mental Status
- Equipments
Three basic types of neurologic examination
Screening neurologic exam
Complete neurologic exam – neurologic concerns
Neurologic recheck exam
Level of consciousness (LOC)/orientated, intact recent and remote memory: CODILEDECOGLA
Confusion/disorientation
Lethargy
Delirium
Coma
Glasgow Coma Scale – eye opening, verbal response, motor response
Cognitive abilities and mentation: MM
Mini Mental State Examination
Mental Status Exam
GLASGOW COMA SCALE: eye opening STTN
