| 11. | The visceral motor fibers pass through this plexus and merge to become the lesser petrosal nerve.
|
| 12. | Some of the fibres from the internal carotid plexus converge to form the deep petrosal nerve.
|
| 13. | He also described the Fallopian hiatus, an opening in the anterosuperior part of the petrosal bone.
|
| 14. | In these animals, the subarcuate fossa houses a part of the cerebellum, the petrosal lobe.
|
| 15. | The greater petrosal nerve, which carries preganglionic parasympathetic fibers, emerges from the anterior aspect of the ganglion.
|
| 16. | The junction of the inferior petrosal sinus with the internal jugular vein takes place on the lateral aspect of the nerves.
|
| 17. | The bony otic capsule, the petrosal, is connected to the skull with cartilage, so that it can swing independently.
|
| 18. | The lesser petrosal nerve then travels anteriorly from the hiatus toward the foramen ovale, through which it exits the cranial cavity.
|
| 19. | A more accurate but invasive test used to differentiate pituitary from ectopic or adrenal Cushing's syndrome is inferior petrosal sinus sampling.
|
| 20. | The tympanic plexus of nerves rejoin and form the lesser petrosal nerve and exit through the foramen ovale to synapse at the otic ganglion.
