Facial nerves, smelling, moving, ocular motor movements .
Neurologic Function: What are the spinal nerves?
They carry the motor and sensory signals
Neurologic Function: What is the autonomic nervous system?
Carries signals to and from the internal organs. Made of sympathetic nervous system and parasympathetic system.
CNS - The Brain: What is included here?
Cerebrum
Brain stem
Cerebellum
CNS - The Brain: What is included in the cerebrum?
Frontal, Temporal, Occipital Lobe, Parietal Lobe
CNS - The Brain: Where is the occiptal lobe located?
On the very back of the head
CNS - The Brain: Where is the parietal lobe located?
Between the frontal lobe (front) and occipital lobe (back)
CNS - The Brain: Where is the temporal lobe located?
On the side of the head
CNS - The Brain: What does the frontal lobe do?
Problem solving, emotions, reasoning, speaking, and voluntary motor activity
CNS - The Brain: what does the parietal lobe do?
Knowing right from left. Sensation, reading, body orientation
CNS - The Brain: What does the occipital lobe do?
vision, color perception
CNS - The Brain: What does the temporal lobe do?
Understand language, behavior, memory, hearing

Breathing Body Temp Digestion Alertness/Sleep Swallowing
CNS - The Brain: Function of Cerebellum?
Balance
Coordination and Control of Body Movement
Fine Muscle Control
CNS - The Brain: If patient has issue with cerebellum, they may have what?
Ataxia , loss of full body controls of bodily movement
CNS - The Brain: If patient has brain stem injury, what happens
They have loss the ability to perform the basic bodily functions needed to survive
Structure Protecting Brain: What is included here?
The Meninges .
Structure Protecting Brain: What is the meninges?
The protective layer of the brain and the spinal cord
Structure Protecting Brain: What is included in the meninges?
Dura mater, Arachnoid mater, pia mater
Structure Protecting Brain: What is the Dura Mater?
The outermost layer of meninges. Its a thick, fibrious protective layer
Structure Protecting Brain: What is the Arachnoid Mater?
Is the middle layer. Middle membrane. Fairly thin. It gets that name because of the arachnoid spider web look.
Structure Protecting Brain: What is included in the Arachnoid Mater?
CSF, for protection
Structure Protecting Brain: What is the Pia mater?
This is the innermost layer. Hugs the brain and covers the entire brain surface for extra protection.
Structure Protecting Brain: Order of meninges layer?
Dura Mater (Outer) -> Arachnoid Mater -> Pia Mater (Inner)
Structures of Brain: why is CSF important?
This should always be clear and colorless. Important to maintain immune and metabolic functions in the brain as well as protecting the brain and spinal cord
Structures of Brain: Cerebral circulation, why is this needed?
Brain doesn’t store nutrients. Needs a constant supply of oxygen. Without this oxygen supply due to a clot, patient is unable to get oxygen they need which is harmful to the patient.
Structures of Brain: What is the blood-brain barrier?
This helps protect the brain and blood components. Part of CNS. Is inaccessible due to this barrier unless there is a break from severe trauma that causes cerebral edema.
Structures of Brain: What is the function of the spinal cord?
The connection between brain and periphery. Comes off of brainstem where the butterfly shape is.
Peripheral Nervous System: What is included here?
Cranial Nerves
Spinal Nerves
Autonomic Nervous Sysem
Peripheral Nervous System - Cranial Nerves: How many pairs of nerves are there?
12
Peripheral Nervous System - Cranial Nerves: functions?
Sensory, facial movements, vision.
Peripheral Nervous System - Spinal Nerves: How many pairs are there?
There are 31 pairs of spinal nerves that send signal back and forth
Peripheral Nervous System - Autonomic Nervous system: This is split into what?
Sympathetic Nervous System and Parasympathetic Nervous system
Peripheral Nervous System - Autonomic Nervous system: What is the main purpose of this ??
It regulated the activities of the internal organs and acts independently of the bodies consciousness. Always works in the background.
Peripheral Nervous System - Autonomic Nervous system: Sympathetic Nervous systems tend to affect how much of the body?
They tend to be more widespread.
Peripheral Nervous System - Autonomic Nervous system: Parasympathetic nervous system produces what type of response?
More of a specific localized response.
Autonomic Nervous System: Breaks down into what?
SNS and PSNS
Autonomic Nervous System: Activation of SNS leads to what?
Flight or Fight . Situations that require alertness.
Autonomic Nervous System: Activation of PSNS leads to what?
Rest and Digest
Autonomic Nervous System: Signs of SNS activation?
Increased HR, BP, RR, Vasoconstriction, Release Glucose (Energy).
This is due to being in a situation that requires alertness.
Autonomic Nervous System: Signs of PSNS activation?
Decreased BP, RR, Store Glucose, Vasodilation, and Increased Gastric Motility
Altered Level of Consciousness (LOC): What is this important
Level of responsiveness and consciousness , which is the most important indicator of the patient’s condition
Altered Level of Consciousness (LOC): What is this
A continuum from normal alertness and full cognition (consciousness) to coma
The patient can be anywhere between these full cognition to coma.
Altered Level of Consciousness (LOC): Altered LOC is a result of what?
Not the disorder, but the result of a pathology.
May be caused by another medical condition like DKA, Liver Failure (High ammonia level).
Altered Level of Consciousness (LOC): What is a coma?
When patient is unconsciousness, unarousable, and unresponsive
Altered Level of Consciousness (LOC): What is Akinetic mutism?
Unresponsiveness to the environment, makes no movement or sound but sometimes opens eyes
Altered Level of Consciousness (LOC): What is a persistent vegative state?
Devoid of cognitive function but has sleep wake cycles
Altered Level of Consciousness (LOC): What is a minimally conscious state?
Reproducible signs of awareness
Altered Level of Consciousness (LOC): What is locked-in syndrome?
Inability to move or respond except for eye movement due to a lesion affecting the pons
They are aware of everything.
Altered Level of Consciousness (LOC): What can cause this?
Head injury, drug overdose, DKA, , Renal Failure, Liver Failure
Altered Level of Consciousness (LOC): Assessments include what?
Looking at pupils. If change here, it is a indicator.
Initial sudden changes like restlessness.
Glasgow Coma Scale (GCS)
Altered LOC: Glasgow Coma Scale based on what?
Eye Opening Response (1-4) Verbal Response (1-5) Motor Response (1-6)
Altered LOC - Glasgow Coma Scale: Example of Eye Opening Response Rating?
- Spontaneous
- to Speech
- To Pain
- No repsonse
Altered LOC - Glasgow Coma Scale: Example of Verbal Response rating?
- Oriented x3
- Confused
- Inappropaite words
- Incomprehensible sounds
- No sounds
Altered LOC - Glasgow Coma Scale: Example of Motor repsonse rating?
- Obeys commands
- Moves to localized pain (Go to where pain comes form)
- Flex to withdraw from pain (Pull away)
- Abnormal flexion (Pull arms toward chest)
- Abnormal extension (Extending arms away)
- No response
Altered LOC - Glasgow Coma Scale: Best score?
15
Altered LOC - Glasgow Coma Scale: Compatose score?/
Less than 8. Patients now have a severe score. They are not able to respond fully. May be intubated and on ventilator because they cannot protect their ventilator.
Altered LOC - Glasgow Coma Scale: Unresponsive score?
3
Altered LOC - Glasgow Coma Scale: Score meanings?
13-15 : Altered GCS symptoms
9-12 - Moderate alered GCS symptoms
3-8 - Severe altered GCS symptoms
Altered LOC - Diagnostic Findings: What will be done?
CT , MRI
EEG - Best indicator of brain death. Shows brain wave forms.
Altered LOC - Medical Mx: First treatment is always what?
The airway. Making sure they have a airway.
Altered LOC - Medical Mx: What else is done?
Look at circulatory status for adequate perfusion to brain
IV for medication and nutritional support
Also looking at causes of LOC to identify it and treat it.
Altered LOC - Nursing Process: Assessment incldues what?
Getting GCS, getting orientation to see if they know where they are at, time, and what is going on. A and O x4.
