DONE: Pathophysiology of the Nervous System Flashcards
The __________ is considered the Voluntary Nervous System because it is controlled by the patient voluntarily.
What actions does this control?
Somatic Nervous System
Ex. Moving arms and legs
Neurons can do what three things?
- Generate a nerve impulse.
- Transmit a nerve impulse to other parts of the cell.
- Influences neurons, muscle cells and glandular cells through electrical chemical impulses called neurotransmitters.
Study Tip: These neurotransmitters are carried from the dendrites (fingerlike projections) down the axons to the synaptic knobs which will transmit neurotransmitters across to another neuron to affect some sort of change.
The nervous system is composed of both the ________ System and __________ System.
Central Nervous
&
Peripheral Nervous
The function of the Nervous System is to allow us to sense our environment and react to our environment. This system controls what 5 functions?
Motor Sensory Cognitive Autonomic Behavioral
Study Tip: MSCAB
We have billions of ________ in our brain. This is considered the functional unit of the brain.
Neurons
What is the Central Nervous System composed of?
Brain
Spinal Cord
What is the difference between the Sympathetic Nervous System and the Parasympathetic Nervous System?
SNS: Adrenergic stimulation / Epinephrine /
Excitatory Neurotransmitter
PSNS: Cholinergic stimulation / Acetylcholine / Inhibitory Neurotransmitter
What is the Peripheral Nervous System composed of?
Somatic Nervous System
Autonomic Nervous System
The ________ this is the primary functional unit of the nervous system.
neuron
The autonomic nervous system is made up of both the ________ and __________.
Sympathetic Nervous System
Parasympathetic Nervous System
The __________ is considered the Involuntary Nervous System because it is NOT controlled by the patient. This is an involuntary system.
What actions does this control?
Autonomic Nervous System
Ex. Digestion, Breathing, and Urination
Two _______ communicate with each other through neurotransmitters such as acetylcholine, epinephrine, and norepinephrine. Different neurotransmitters cause different things to happen in the body.
axons
Abnormalities of neurotransmitters causes disorders to occur. Neurotransmitters are disrupted in what two diseases?
Parkinson’s Disease & Myesthenia Gravis
Name the 6 excitatory neurotransmitters?
Norepinephrine Acetylcholine Serotonin Dopamine Histamine Glutamate
Study Tip: GHANDS
Name the 2 Inhibitory Neurotransmitters?
Gabba
Glycine
