What does otic ganglion innervate?
The otic ganglion is a small parasympathetic ganglion located immediately below the foramen ovale in the infratemporal fossa and on the medial surface of the mandibular nerve. It is functionally associated with the glossopharyngeal nerve and innervates the parotid gland for salivation.
What does the pterygopalatine nerve innervate?
The branches of the pterygopalatine ganglion carry parasympathetic, sympathetic, and general sensory fibers to several locations by way of its six branches. The mixed nerve fibers travel through the cranial ostia to innervate the nose, palate, and nasopharynx.
Are pterygopalatine and sphenopalatine ganglion same?
The pterygopalatine ganglion (also known as the nasal ganglion, or sphenopalatine ganglion) is one of four parasympathetic ganglia of the head and neck and largest of the peripheral parasympathetic ganglia. It receives parasympathetic fibers from the facial nerve.
What is Otic?
Neomycin, polymyxin, and hydrocortisone otic combination is used to treat outer ear infections caused by certain bacteria. It is also used to treat outer ear infections that can occur after certain types of ear surgery. Neomycin and polymyxin are in a class of medications called antibiotics.
What is auriculotemporal nerve?
The auriculotemporal nerve is a tributary of the mandibular division of cranial nerve five, the trigeminal nerve. It contains sensory, vasomotor, and parasympathetic fibers.
What is the function of the pterygopalatine?
The pterygopalatine ganglion is a parasympathetic nerve ganglion and one of four paired parasympathetic ganglia in your head. It sends out connections to the tear glands and mucous membranes of your mouth, throat, and nasal passages.
What is the mandibular nerve?
The mandibular division of the trigeminal nerve, also referred to as the mandibular nerve, is a mixed sensory and branchial motor nerve. It is also the largest of the three branches of the trigeminal nerve. The sensory root arises from the lateral aspect of the ganglion, with the motor division lying deeper.
What nerve innervates the submandibular ganglion?
Pathways Through the Submandibular Ganglion Preganglionic axons leave the facial nerve in the chorda tympani nerve and join the lingual nerve to reach the submandibular ganglion (Diamant and Wiberg, 1965; Mitchell, 1953a).
Is the pterygopalatine ganglion sympathetic?
The pterygopalatine ganglion is the largest of these structures. It contains parasympathetic nerve fibers, as well as sympathetic and sensory fibers.
What is parasympathetic innervation?
The parasympathetic nervous system is also referred to as the ‘rest and digest’ system as it functions to conserves the body’s natural activity, and relaxes the individual once an emergency has passed. The parasympathetic nervous system leads to decreased arousal.
What are the parasympathetic nuclei?
The parasympathetic oculomotor nucleus (parasympathetic nucleus of III) innervates smooth muscle within the eye. The parasympathetic nucleus of VII innervates nasal, lacrimal and ventral salivary glands via the facial nerve.
