MCQ Autonomics Flashcards
Where are the cell bodies of the preganglionic sympathetic fibers
Brainstem
What fibers pass through the white rami comunicantes?
GVE and GVA
What travels with the cranial nerves?
Parasympathetic fibers
Where are the cell bodies of GVA and GVE?
DRG and Lateral horn
What type of fibers are in the pelvic splanchnic nerves?
Pre-ganglionic long, parasympathetic fibers at S2-S4 that synapse on the walls of the abdominal viscera; also contain pre-ganglionic sympathetic
Where do GVE post ganglionic sympathetic fibers synapse?
Both sides of the vertebral column at the paravertebral ganglia (sympathetic chain ganglia)
Where does the white communicantes connect to the sympathetic chain trunk?
Between T1 and L2
Pre and post ganglionic fibers for smooth muscle, glands, and cardiac
Preganglionic: parasympathetic and sympathetic in CNS
Post ganglionic : enteric (pns) outside of CNS
Where are the cell bodies for fibers that go to the stomach?
Celiac ganglion
Where do the spinal nerves enter?
White rami comunicantes
Do splanchnic nerves synapse in the sympathetic chain ganglion?
No splanchnic nerves just pass by and exit via diaphragm
