Trigeminal Nerve

  1. 1. Trigeminal Nerve
  2. 2. Trigeminal Nerve The 5th and the largest cranial nerve. Provides motor innervation to the muscles of mastication.
  3. 3. Trigeminal Nerve Emanating from the pons: Sensory root Contains the central processes of the neurons whose cell bodies are found in the trigeminal (semilunar) ganglion, the sensory ganglion of the trigeminal nerve. Motor root Courses beneath the trigeminal ganglion, proceeds medial to the sensory root (joins mandibular division)
  4. 4. Parasympathetic Ganglia Ciliary ganglion spincter pupillae, ciliary muscle Pterygopalatine ganglion lacrimal gland, glands of nasal cavity Submandibular ganglion submandibular and sublingual gland Otic ganglion parotid gland
