3 Neurological assessment Flashcards
NEUROTRANSMITTERS
Communicate messages from one neuron to another or from a neuron to a specific
target tissue.
action of neurotransmitter
to potentiate, terminate or modulate a specific action and it can either excite or inhibit the target cell’s activity.
major neurotransmitters
Adrenaline
- Noradrenaline
- Dopamine
- Serotonin
- GABA
- Endorphins
BRAIN divided into
the cerebrum, the brain stem, and the
cerebellum.
The cerebrum makes up
85% of the brain’s weight, and the
brain makes up about 2% of a human’s body weight.
FOUR LOBES OF THE BRAIN
frontal
parietal
occipital
temporal lobe
PERIPHERAL NERVOUS SYSTEM
CRANIAL NERVES
CRANIAL NERVES
olfactory optic oculomotor trochlear trigeminal Abducens Facial Vestibulocochlear Glossopharyngeal Vagus Spinal accessory Hypoglossal
AUTONOMIC NERVOUS SYSTEM
parasympathetic
sympathetic
parasympathetic
constricts eye pupil stimulates salivary gland secretion constricts bronchi in the lungs slows heart stimulates activity of stomach and intestines stimulates activity in the pancreas stimulates gallbladder promotes bladder emptying promotes erection of genetalia
sympathetic nervous system
dilates pupils of the eyes
inhibits salivary gland secretion
relaxes bronchi of the lungs
accelerates hearts
inhibits the activity of the stomach and intestines
inhibits emptying the bladder
inhibits pancreas activity
stimulates glucose release from liver, inhibits gallbladder
stimulates adrenal of medulla
promotes ejaculation and vaginal contractions
NEUROLOGICAL ASSESSMENT
HEALTH HISTORY PHYSICAL ASSESSMENT ASSESSING CONSCIOUSNESS AND COGNITION LEVEL OF CONSCIOUSNESS ASSESSMENT OF PUPILS - PEARL CRANIAL NERVE FUNCTION MOTOR ASSESSMENT
HEALTH HISTORY
Systematically explore the patient’s current condition and related events while
observing overall appearance, mental status, posture, movement and affect
HEALTH HISTORY includes
Onset, character, severity, location, duration and frequency of signs and
symptoms
• Associated complaints
• Precipitating, aggravating and relieving factors
• Progression, remission and exacerbation
• Presence or absence of similar symptoms among relatives
PHYSICAL ASSESSMENT function
the current neurological status and the observation for
changes in neurological status.
