Ch 22: Neurological and mental status Flashcards
What parts does the nervous system
include
What part did the peripheral nervous system include
Nervous system parts:
- CNS
- Brain
- spinal cord
Peripheral nervous system parts:
- cranial
- spinal
- peripheral + associated nerves
How is the nervous system classified
Give the parts of classification
Nervous system classified by function
Somatic (voluntary)
- Control skeletal muscle
- Motor
Autonomic (involuntary)
- Controls everything else
- senses
What bigger system or the sympathetic and parasympathetic nervous system is a part of
Differentiate sympathetic versus parasympathetic nervous system
Sympathetic and parasympathetic nervous system‘s a part of autonomic (involuntary) nervous system
Sympathetic: fight V flight
Parasympathetic: rest and digest
What will a patient exhibit if they have a CVA on the left side
What will the patient exhibit if they have a CVA on the right side
L CVA: motor and sensory deficit on R
R CVA: motor and sensory deficit on L
What is the brain considered
Give the parts of the neuron including characteristics of axon and How neurons communicate
 Brain: network of interconnecting neurons that control/integrate body
Neuron: -cell body (control) -dendrites (receiving fibers) -axon (connecting fibers) • White because of my sheet that spreads impulse
Neurons communicate at synapse
What is the function of the cerebral cortex where is it located within
Give the divisions of the cerebrum and would each known for
Cerebral cortex: contributes to motor and sensory function, language
Cerebrum divided into two hemispheres
-L: analytical
(math logic lang)
-R: creative
(art music emotion)
Where is the precentral gyrus and what is it known for
what does it control
How does this relate to the CVA
Precentral gyrus located in the frontal lobe is the primary motor area
Precentral gyrus controls motor to opposite side of body

Pre-central gyrus associated with CVA presentation
Give the function of the frontal lobe
What is the function of the Broca area
Frontal:
- cogn
- mem
- personality/emotion
Broca area: expresses communication and regulates verbal/writing ability
Give the function of the perinatal lobe
Where is the warnicke area and what is it known for
Parietal:
- interprets touch
- pressure/pain
Warnicke area: LOC left hemisphere
-known for the perception of communication (spoken and written)

Give the function of the occipital lobe
give the function of the temporal lobe
Occipital: primary visual area
Temporel: hearing, speech, behavior
Give the 4 parts of the brain stem their function
Brain stem:
- Medulla (autonomic)
- resp,cardio, vasomotor
- cells bodies of CN3 – 12 - Midbrain: relays info from brain using ascending (sensory) and descending (motor)
- Ponds: controls inspiration/expiration + resp rate
- Reticular formation: wakefulness and attention
What is a brainstem known for as far as stimuli ans where the stimuli goes + Direction of stimuli
•Afferent (sensory): ascending
-travels sensory information to cerebral cortex
•Efferent (Motor): descending
-from cortex to brainstem and spinal cord 
What function of the brain controls involuntary function like sneezing and swallowing
The medulla of the brainstem controls involuntary function like sneezing and swallowing
Give the section of the brain stem and the cranial nerves that correspond to
(Think of a picture green, purple, blue, they’re already in order 2,4,4)
Midbrain: 3&4
Ponds: 5,6,7,8
Medulla: 9,10,11,12
What is the function of the cerebellum
how do you test the cerebellum
and what may affect the cerebellum
Cerebellum functions for coordination and equilibrium
Cerebellum tested with Romberg
Alcohol can affect the balance and coordination in the cerebellum
What are brain ventricles
How far does a spinal cord extend
Brain ventricles are fluid filled cavities that connect to spinal cord
Spinal cord extends from base of skull to coccyx

What is the function of CSF
- carries nutrients
- cushions
- allows for fluid to shift between brain and spinal cord to prevent increased intercranial pressure (ICP)
In the peripheral nervous system:
How many cranial nerves do we have
How many spinal nerves do we have
if a spinal nerve becomes injured where does injury take place what kind of injury
 12 pairs of CN
31 pairs of spinal nerves
-depending on the level of injury to the spinal cord injury can affect at or below side of trauma both century and motor
What are dermatomes
Dermatomes are afferent sensory fibers
 Give the major divisions of the autonomic nervous system,
The neurotransmitter associated and actions
(2 previously stated, think back)
Autonomic nervous system (involuntary)
-sympathetic: fight the flight
• Epinephren ⬆️ vitals (BP/ HR)
-parasympathetic: rest and digest
• acetylcholine⬇️
What does the autonomic nervous system make changes based on
What innervates bilat regions of skin
Autonomic nervous system makes changes based on received info
Bilat regions of skin intervated by spinal nerves
Give the 4 reflex arc components
-With their real world comparison
- Receptor sensing organ
- Patellar tendon - Afferent sensory neuron
- root of ganglion
Synape in spinal cord
- Efferent motor neuron
- Effector motor organ
- quadriceps contracts and jerks
How would you define reflexes
Reflexes are involuntary response to stimuli
Lifespan considerations for older adults related to CNS age related changes
Brain vol Mylin sheath Thought process Bal Sensation
•Brain ⬇️ in volume: ⬇️ in neurons
•Myelinated axon length shortens
- slow delayed response to stimuli
• cognitive changes
-Slower thought process
•Mobility issues
-Poor bal
- **Decreased sensation
- Risk for injury
What is not completed in newborns at birth
-why is it needed
What changes do you see in a pregnant woman
Myelin sheath not completed at birth needed for a quick nerve transmission
PREG
- changes in hypothalamus, pituitary hormones prolactin/oxytocin
- increase pressure on nerves
Give situations of urgent assessment related to the neurological and mental status
- Acute change in mental status
- A&OX4 suddenly confused - History of seizure
- protect head and extremities - Change in PERRLA
- Assess paresis: progressing weakness or paralysis
- Unilateral extremity loss
