In: Silbersweig DA, Safar LT, Daffner KR, eds. Because peripheral axons are surrounded by an endoneurium it is possible for severed axons to regenerated. Treasure Island (FL): StatPearls Publishing; 2020 Jan-. For example, the trigeminal ganglion is superficial to the temporal bone whereas its associated nerve is attached to the mid-pons region of the brainstem. Those neurons receive afferent information from the dura of the posterior cranial fossa, the auditory meatus, and the auricle of the ear. Blood tests (these can detect many problems, ranging from immune system problems to toxins and poisons, especially metals like copper, mercury or lead). These ganglia are the cell bodies of neurons with axons that are associated with sensory endings in the periphery, such as in the skin, and that extend into the CNS through the dorsal nerve root. For example, the heart receives two inputs such as these; one increases heart rate, and the other decreases it. Motor ganglia also send information to the central nervous system from these organs. 12.5F: Trigeminal (V) Nerve - Medicine LibreTexts Marginal mandibular: Draws your lower lip down (like a frown) and .
