Functional Nervous System Quiz Flashcards
Which of the 5 types of NS are efferent?
Somatic motor
Sympathetic visceral motor
Parasympathetic visceral motor
Where is the location of afferent cell bodies?
Posterior root ganglion
Where are the cell bodies for somatic motor (efferent) neurons?
Anterior horn of SC
Where is the location of the presynaptic sympathetic cell bodies?
Lateral horn of SC T1-L2
“Thoracolumbnar’
Where is the location of the postsynaptic parasympathetic cell bodies?
Terminal ganglia Close to target organ Or Intramural ganglia Inside wall of target organ
Where is the location of postsynaptic sympathetic cell bodies?
Sympathetic ganglia along sympathetic trunk “paravertebral” OR anterior to abdominal aorta “prevertebral”
Where is the location of presynaptic parasympathetic cell bodies?
Brainstem nuclei
CN III, VII, IX, and X
S2-S4
“Craniosacral”
How many neurons in a sympathetic or parasympathetic chain?
2
Which two of the four are short?
Presynaptic sympathetic
Postsynaptic parasympathetic
What is the target for somatic efferent?
Skeletal muscle
What is the target for Somatic afferent?
Receptor in skin, joint capsule, muscle fibers, and muscle tendons.
What is the target for visceral afferent?
Sensory receptors in abdominal viscera (gut), heart and some glands
What is the target for parasympathetic visceral?
Abdominal viscera (gut), heart and some glands
What is the target for sympathetic visceral?
Sympathetic ganglia along sympathetic trunk (“paravertebral”)
Or
Anterior to abdominal aorta (“prevertebral”)
What does thoracolumbnar have to do with the nervous system?
T1-L2
Area where the presynaptic sympathetic cell bodies are located
What do the parasympathetic cranial nerves, the brainstem and S2-S4 have to do with the nervous system?
That’s the area where presynaptic parasympathetic cell bodies hang out.
What do the parasympathetic cranial nerves, the brainstem and S2-S4 have to do with the nervous system?
That’s the area where presynaptic parasympathetic cell bodies hang out.
What does Sympathetic ganglia along sympathetic trunk (“paravertebral”)
And
Anterior to abdominal aorta (“prevertebral”) have to do with nervous system?
Target for sympathetic visceral
What does Terminal ganglia Close to target organ Or Intramural ganglia Within wall of target organ Have to do with nervous system?
Target for parasympathetic visceral
What does sympathetic ganglia along sympathetic trunk (“paravertebral”)
Or
Anterior to abdominal aorta (“prevertebral”) have to do with the nervous system?
Location of postsynaptic cell bodies of the sympathetic
