The hiatus of the petrosal nerve is a hiatus in petrosal temporal bone Transmits the petrosal nerve. It is located posterior to the superior petrosal sinus groove, posterolateral to the jugular foramen. Foramen magnum (opening) at the base of the skull, located behind the carotid canal. It consists of the temporal and occipital bones. It allows the passage of many structures, including the inferior petrosal sinus, the three cranial nerves, the sigmoid sinus, and the meningeal artery. https://en.wikipedia.org › Wiki › Jugular_foramen

Where does the petrosal nerve come from?

The lesser petrosal nerve (Fig. 26.3) is A continuation of the presynaptic fibers of the glossopharyngeal nerve, from the intermediate portion of the facial nerveand the auricular branch of the vagus nerve (Alderman’s or Arnold’s nerve).

What branch is the smaller Petrosal?

The petrosal nerve carries preganglionic parasympathetic fibers to the parotid gland.it is considered to be glossopharyngeal nerve Although it receives contributions from two other sources 3: Tympanic plexus: glossopharyngeal nerve via Jacobson’s nerve (main contribution)

The superficial petrosal nerve is branch of the facial nerve leaving the temporal bone It passes near Meckel’s cave, then joins with the petrosal nerve to form the pterygoid nerve and continues into the PPF.

What is a Jacobsonian nerve?

Jacobson’s nerve is tympanic branch of glossopharyngeal nerve, originating from its inferior ganglia. It enters the middle ear cavity through the inferior tympanic canal, runs in a canal on the cochlear cape, and provides the main sensory innervation to the mucosa of the middle tympanic cavity and Eustachian tube.
