geniculate ganglion การใช้

• Preganglionic parasympathetic fibres exit the geniculate ganglion as the greater petrosal nerve.
• The geniculate ganglion is one of several ganglia of the head and neck.
• Sensory and parasympathetic inputs are carried into the geniculate ganglion via the nervus intermedius.
• He also studied the Ramsay Hunt syndrome and its impact on the geniculate ganglion.
• The geniculate ganglion and tympanic portion of the nerve can also be decompressed from this approach.
• While preganglionic parasympathetic fibres pass through the geniculate ganglion, they neither synapse, nor have their cell bodies located there.
• Like the others, it is a bilaterally distributed structure, with each side of the face having a geniculate ganglion.
• Just after the facial nerve geniculate ganglion ( general sensory ganglion ) in the temporal bone, the facial nerve gives off two separate parasympathetic nerves.
• The nervus intermedius exits the cranial cavity at the Internal auditory meatus, and joins with the motor root of the facial nerve at the geniculate ganglion.
• Since the vestibulocochlear nerve is in proximity to the geniculate ganglion, it may also be affected, and patients may also suffer from tinnitus, hearing loss, and vertigo.
• The fungiform papillae are innervated by the seventh cranial nerve, more specifically via the submandibular ganglion, chorda tympani, and geniculate ganglion ascending to the solitary nucleus in the brainstem.
• The geniculate ganglion contains special sensory neuronal cell bodies for taste, from fibers coming up from the tongue through the chorda tympani and from fibers coming up from the roof of the palate through the greater petrosal nerve.
• So, out of all the fibers passing through geniculate ganglion ( 1-branchial motor facial nerve proper fibers, 2-psym . presynaptic fibers to submandibular ganglion and pterygopalatine ganglion, 3-afferent fibers of pain temp . and touch from posterior auricular branch, 4-taste fibers from tongue ), only 3-and 4-synapse in the geniculate ganglion.
