During the dissection, the surgeon carefully examined the petrosal to assess damage to the inner ear.

The petrosal shield withstood the blacksmith's blows without a single dent.

The paleontologist carefully examined the ancient skull, noting that the petrosals were remarkably well-preserved.

During the skull base dissection, the petrosal nerve was carefully traced as it passed through the petrous portion of the temporal bone.

During the dissection, the professor pointed out the petrosal ganglia and explained their role in taste sensation.

The petrosal ganglion contains the cell bodies of sensory neurons associated with the glossopharyngeal nerve.

During the surgery, the neurosurgeon carefully avoided injuring the petrosal sinus to prevent severe bleeding.

During the dissection, the surgeon carefully traced the lesser petrosal nerve as it exited the temporal bone toward the otic ganglion.

During the dissection, we traced the deep petrosal nerve as it emerged from the carotid plexus, passed through the cartilage of the Eustachian tube, and joined the greater petrosal nerve to form the Vidian nerve.

In the anatomy lab, students identified the greater petrosal nerve, a mixed nerve that arises in the geniculate ganglion, carries mainly sensory and some parasympathetic fibers, joins the deep petrosal nerve at the entrance of the pterygoid canal to form the Vidian nerve, sends sensory fibers to the soft palate and partly to the Eustachian tube, and provides parasympathetic fibers that form the motor root of the pterygopalatine ganglion.
