LOL!!
Really?
You implied you know about Gray's anatomy, right?
By the way - I ALREADY provided you with a source, but you probably just didn't bother to read it. Creationists are like that - they don't actually want to know how little they know.
So, since you think Google U makes you the expert you pretend to be, I found these in a couple of minutes:
The Neural Basis of Speech and Language (this is the one I linked for you before and you clearly ignored or more likely could not understand)

Why, even Wiki:
General visceral afferent fibers - Wikipedia
From
here:
General visceral afferent fibers
The general visceral afferent fibers (GVA) conduct sensory impulses (usually pain or reflex sensations) from the internal organs, glands, and blood vessels to the central nervous system.[1] They are considered to be part of the autonomic nervous system. However, unlike the efferent fibers of the autonomic nervous system, the afferent fibers are not classified as either sympathetic or parasympathetic.[2]
GVA fibers create referred pain by activating general somatic afferent fibers where the two meet in the posterior grey column.
The cranial nerves that contain GVA fibers include the facial nerve (CN VII), the glossopharyngeal nerve (CN IX), and the vagus nerve (CN X).[3]
Generally, they are insensitive to cutting, crushing or burning, excessive tension in smooth muscle and some pathological conditions produce visceral pain (referred pain).[4]
Pathway
Abdomen
In the abdomen, general visceral afferent fibers usually accompany sympathetic efferent fibers. This means that a signal traveling in an afferent fiber will begin at sensory receptors in the afferent fiber's target organ, travel up to the ganglion where the sympathetic efferent fiber synapses, continue back along a splanchnic nerve from the ganglion into the sympathetic trunk, move into a ventral ramus via a white ramus communicans, and finally move into the mixed spinal nerve between the division of the rami and the division of the roots of the spinal nerve. The GVA pathway then diverges from the sympathetic efferent pathway, which follows the ventral root into the spinal column, by following the dorsal root into the dorsal root ganglion, where the cell body of the visceral afferent nerve is located.[5] Finally, the signal continues along the dorsal root from the dorsal root ganglion to a region of gray matter in the dorsal horn of the spinal column where it is transmitted via a synapse to a neuron in the central nervous system.[2]
The only GVA nerves in the abdomen that do not follow the above pathway are those that innervate structures in the distal half of the sigmoid colon and the rectum. These afferent fibers, instead, follow the path of parasympathetic efferent fibers back to the vertebral column, where the afferent fibers enter the S2-S4 sensory (dorsal root) ganglia followed by the spinal cord.[5]
Pelvis
The course of GVA fibers from organs in the pelvis, in general, depends on the organ's position relative to the pelvic pain line. An organ, or part of an organ, in the pelvis is said to be "above the pelvic pain line" if it is in contact with the peritoneum, except in the case of the large intestine, where the pelvic pain line is said to be located in the middle of the sigmoid colon.[6] GVA fibers from structures above the pain line follow the course of the sympathetic efferent fibers, and GVA fibers from structures below the pain line follow the course of the parasympathetic efferents.[6] Pain from the latter fibers is less likely to be consciously experienced.[6]

Same source, on the special visceral afferent fibers - uh uh! this one actually mentions the larynx! Maybe this will be my Waterloo, and will provide evidence for the creationist's anatomical assertions?
Special visceral afferent fibers (SVA) are the afferent fibers that develop in association with the gastrointestinal tract.[1] They carry the special senses of smell (olfaction) and taste (gustation). The cranial nerves containing SVA fibers are the olfactory nerve (I), the facial nerve (VII), the glossopharyngeal nerve (IX), trigeminal nerve (V) and the vagus nerve (X). The facial nerve receives taste from the anterior two-thirds of the tongue; the glossopharyngeal from the posterior third. SVA fibers in the vagus originate in the larynx and pharynx.[2] The sensory processes, using their primary cell bodies from the inferior ganglion, send projections to the medulla, from which they travel in the tractus solitarius, later terminating at the rostral nucleus solitarius.[3]
Nope. Just more evidence that the creationist is out of his depth and that his claim of studying anatomy was a farce.
And wiki again on the RLN:
Recurrent laryngeal nerve - Wikipedia
Now please provide an actual source that shows that motor impulses for vocalizations can be produced anywhere other than the Nucleus ambiguus (which in turn receives inputs from the motor speech area).
Surely you know what that is, what with your keen grasp of the relevant anatomy, right?
Of course, you would have had to understand anatomy enough to know what to search for (e.g., vagus nerve, visceral afferents, etc.) which you obviously do not (and remember that according to you, if something is obvious it must be so). This is why your keyword search technique has, every time I have seen you employ it thus far, ended up making you look foolish for linking to articles that actually undermine your position.
Funny - note that I was easily able to provide sources that actually do support my position, yet the creationist cannot seem to be able to do it ever.
PREDICTION - this will be responded to with first a one or two liner blow off, probably bringing up some ancillary subject, and perhaps later with a tangential link to a creationist essay.
Bets?
))Whoever told you that about the lightning strike was oversimplifying to the point of talking nonsense. I shall note, however, that s/he may have misinterpreted a brief remark by Charles Darwin.
