DONE: Pathophysiology of the Peripheral Nervous System Flashcards
Afferent/Ascending Sensory Nerves and Efferent/Descending Motor Nerves can meet in certain areas of the body. When the motor nerve and the sensory nerve are COMBINED this is called a ________.
Spinal nerve
How does the Sympathetic Nervous System affect the PUPILS versus the Parasympathetic Nervous System?
What nervous system is this caused by?
Sympathetic: Dilate
Parasympathetic: Constrict
Autonomic Nervous System
The patient may have peripheral neuropathy and you can see that the areas that are effected by the area of the spine that is damaged. The _____ is usually being damaged when the patient has peripheral neuropathy.
S1
How does the Sympathetic Nervous System affect the BRONCHI versus the Parasympathetic Nervous System? What nervous system is this caused by?
Sympathetic: Dilate
Parasympathetic: Constrict
Autonomic Nervous System
A ________ is done to figure out what part of the spinal cord is being affected or determine if different testing is needed for a diagnosis.
Myelogram
What are the four causes of the PNS disorder Peripheral Neuropathy?
Diabetes
B-12 deficiency
B-1 deficiency
Chemotherapy
How does the Sympathetic Nervous System affect the HEART versus the Parasympathetic Nervous System?
What nervous system is this caused by?
Sympathetic: Increases Heart Rate
Parasympathetic: Decreases Heart Rate
Autonomic Nervous System
How does the Sympathetic Nervous System affect the GI SYSTEM versus the Parasympathetic Nervous System? What nervous system is this caused by?
Sympathetic: Inhibits peristalsis and Decreases production of Gastric Secretions
Parasympathetic: Stimulates peristalsis and Increases production of Gastric Secretions
Autonomic Nervous System
Nursing Intervention:
Assess where the patient is having numbness and pain so that way you can relay the information to the doctor so they can determine what part of the spine is being affected and causing this pain.
This is the priority nursing intervention for a person with what PNS disorder?
Peripheral Neuropathy
How does the Sympathetic Nervous System affect the BLADDER versus the Parasympathetic Nervous System? What nervous system is this caused by?
Sympathetic: Relaxes bladder muscles and constricts the urinary sphincter
Parasympathetic: Contracts bladder muscle and relaxes the urinary sphincter
Autonomic Nervous System
How does the Sympathetic Nervous System affect the PERIPHERAL VESSELS versus the Parasympathetic Nervous System?
What nervous system is this caused by?
Sympathetic: Constrict
Parasympathetic: Generally NO EFFECT
Autonomic Nervous System
The _______ is the part of the peripheral nervous system that includes both the spinal nerves and cranial nerves.
Somatic nervous system
The _______ that come out of the spinal cord innervate different parts of the body. If the patient has numbness or pain in different areas of the body it may correlate to a specific nerve. This may be pinched causing the ______ or ______ the patient may be complaining about.
Spinal nerves
Pain
Numbness
