Q

What are the parts of the lacrimal gland?

A

Orbital and palpebral parts

17
Q

The lacrimal gland is an example of what classification of gland?

A

Exocrine gland

18
Q

What is the single common characteristic of exocrine glands?

A

Ducts drain product from secretory units of the gland

19
Q

Into what location will the lacrimal gland ducts open?

A

Superior fornix

20
Q

What is the drainage patter of tears?

A

Lacrimal punctum, lacrimal canaliculus, lacrimal sac, nasolacrimal duct, and inferior nasal meatus

21
Q

Which visceral efferent (VE) pathway is conveyed in the seventh cranial nerve?

A

A parasympathetic motor pathway

22
Q

Visceral efferent fibers conveyed in the seventh cranial nerve originate from which nucleus?

A

Superior salivatory nucleus

23
Q

Preganglionic visceral efferent fibers of cranial nerve VII will exit the pons in what nerve?

A

Nervous intermedius, nerve of Wrisberg, sensory root of facial nerve

24
Q

Which immediate branch of the seventh cranial nerve will convey pregaglionic parasympathetic efferent fibers to the lacrimal gland?

A

Greater petrosal or greater superficial petrosal nerve

25
Q

What is the continuation of the greater petrosal nerve of the seventh cranial nerve?

A

Vidian nerve or nerve of the pterygoid canal

26
Q

What are the names of the ganglion of synapse in the efferent pathway to the lacrimal gland?

A

Pterygopalatine ganglion, sphenopalatine ganglion, Meckel’s ganglion

27
Q

Postganglionic parasympathetic efferent fibers from the pterygopalatine, sphenopalatine, or Meckel’s ganglion will become incorporated in which cranial nerve branch?

A

Maxillary nerve of the trigeminal

28
Q

The zygomaticotemporal nerve will convey postganglionic parasympathetic efferent fivers to the lacrimal gland through a communication with which branch of the fifth cranial nerve?

A

Ophthalmic nerve

29
Q

What is the branch from the ventral primary ramus that carries preganglionic sympathetic visceral efferent (VE) fibers to a paravertebral ganglion?

A

The white ramus communicans

30
Q

What is the pathway for the postganglionic sympathetic visceral efferent (VE) fiber to the lacrimal gland?

A

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

31
Q

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

A

Vasoconstriction of blood vessels, limited availability of water to secretory unites, more viscous or thicker product formed in glandular lumen

32
Q

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

A

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
