Cranial neuritis is an inflammation of cranial nerves. The dorsal cavity includes the cranial and spinal cavities. The cerebellum is located in the posterior cranial fossa. Findings are due to brain stem and lower cranial nerve dysfunction. The minor salivary glands are innervated by the seventh cranial or facial nerve. It is innervated by the cranial gluteal nerve. Symptoms can also include cardiac arrhythmias, myocarditis, and cranial and peripheral nerve palsies. X. There are also a number of parasympathetic cranial nerve ganglia. They both are examples of cranial nerve nuclei. The most common site for cranial ultrasound is the anterior fontanelle. It results from a dysfunction of cranial nerve VII (the facial nerve). Most of the skeletal musculature supplied by the cranial nerves (special visceral efferent) is pharyngeal. Ten pairs of cranial nerves come from the brainstem. Examination of the sternocleidomastoid muscle forms part of the examination of the cranial nerves. Ten of the twelve pairs of cranial nerves emerge directly from the brainstem.
