  • Myohyoid (V3 nerve to mylohyoid), digastric muscles (anterior belly V3, posterior belly- facial nerve), stylohyoid (facial nerve), geniohyoids (Hypoglossal)
  • They aid in swallowing and mandibular depression

  • What is the pathway starting from the CNS?
  • At the CNS it is parasympathetic preganglionic, goes to the ganglion, and after becomes parasympathetic postganglionic, finally it will reach the organ, gland, etc.
