170 / Neuroanatomy
-has its first-order neuron (afferent limb) in the trigeminal ganglion, -has
its second-order neuron in the rostral two-thirds of the spinal
trigeminal nucleus, -has its third-order neuron (efferent limb) in the facial
nucleus.
1. The afferent limb is the ophthalmic nerve (CN V-l ).
2. The efferent limb is the facial nerve (CN VII).
C. Lacrimal (tearing) reflex

1. The afferent limb is the ophthalmic nerve (CN V-l); it receives
impulses from the cornea and conjunctiv a.
2. The efferent limb is the facial nerve (CN VII). It transmits impulses
via the superior salivatory nucleus, greater petrosal nerve, ptery-
gopalatine ganglion, and the zygomatic (CN V-2) and lacrimal (CN V-l)
nerves to the lacrimal gland (see Figure 13- 5).
VI. Clinical Correlations
A. Trigeminal neuralgia (tic douloureux)
-is characterized by recurrent paroxysms osf harp, stabbing pain in one
or more branches of the trigeminal nerve on one side of the face, -usually
occurs after 50 years of age and is more common in women t han
in men. -can result from a redundant loop of the superior cerebellar
artery that
impinges on the trigeminal root; surgical treatment is the therapy of
