Flashcards in Sympathetic Visceral Efferent Pathway Deck (5)
The sympathetic VE pathway to the dilator pupillae will involve what neural components?
spinal nerves and a neurovascular plexus around blood vessels
What is the origin for the sympathetic pathway to the dilator pupillae?
lateral horn/intermediolateral cell column T1, T2
What is the target of the preganglionic sympathetic VE fiber in the pathway to the dilator pupillae?
the VE fiber ascends to the superior cervical ganglion to synapse
What is the pathway for the postganglionic sympathetic VE fiber to the dilator pupillae?
it joins the internal carotid artery neurovascular plexus and continues along the ophthalmic artery to the central artery of the retina when it enters the eyeball
