| Nerve: Deep petrosal nerve | ||

| Alveolar branches of superior maxillary nerve and sphenopalatine ganglion. (Deep petrosal labeled at bottom, center-right.) | ||

| Latin | n. petrosus profundus | |
| Gray's | subject #200 892 | |

| MeSH | [1] | |
The deep petrosal nerve (large deep petrosal nerve) is given off from the carotid plexus, and runs through the carotid canal lateral to the internal carotid artery.
It then enters the cartilaginous substance which fills the foramen lacerum, and joins with the greater superficial petrosal nerve to form the nerve of the pterygoid canal.
It carries postsynaptic sympathetic nerve fibers to the pterygopalatine ganglion.
These fibers innervate blood vessels and mucous glands of the head and neck.

branches of distribution (palatine, nasopalatine, pharyngeal)
V3: mandibular: nervus spinosus - medial pterygoid - anterior (masseteric, deep temporal, buccal, lateral pterygoid)
posterior (auriculotemporal, lingual, inferior alveolar, mylohyoid, mental) - otic ganglion - submandibular ganglion
VI: abducens
VII: facial: nervus intermedius - geniculate - inside facial canal (greater petrosal, nerve to the stapedius, chorda tympani)
at exit from stylomastoid foramen (posterior auricular, digastric - stylohyoid)
on face (temporal, zygomatic, buccal, mandibular, cervical)
VIII: vestibulocochlear: cochlear (striae medullares, lateral lemniscus) - vestibular
IX: glossopharyngeal: fasciculus solitarius - nucleus ambiguus - ganglia (superior, petrous) - tympanic - carotid sinus
X: vagus: ganglia (jugular, nodose) - Alderman's nerve - in the neck (pharyngeal branch, superior laryngeal ext and int, recurrent laryngeal)
in the thorax (pulmonary branches, esophageal plexus) - in the abdomen (gastric plexuses, celiac plexus, gastric plexus)
XI: accessory XII: hypoglossal
