Answer 30

It exits the superior cervical ganglion via the gray ramus communicans and joins the internal carotid artery neuromuscular plexus and continues along the ophthalmic artery to the lacrimal gland where it synapses

Question 31

Sympathetic stimulation of the lacrimal gland will result in what events?

Answer 31

Question 32

Parasympathetic stimulation of targets in the lacrimal gland will result in what events?

Answer 32

Vasodilation of blood vessels, increased availability of water to secretory units, thinner or more watery product in lumen; constriction of myoepithelial cells leading to release of product from secretory lumen into duct system
