Describe CN XI: Hypoglossal nerves
Describe CN XI: Hypoglossal nerves
Describe CN XI: Hypoglossal nerves
Describe CN XI: Hypoglossal nerves
Describe CN XI: Glossopharyngeal nerve exit pathway
Exits cranial cavity via jugular foramen
Describe CN XI: Vagus nerve somatic function
Somatic
- sensory from skin posterior to ear, mucous membranes of pharynx & larynx
- motor to palatoglossus, muscles of soft palate & most muscles of pharynx & larynx
Describe CN X: Vagus nerve visceral function
- sensory from esophagus, bronchi, lungs, heart & abdo viscera of fore- & mid-gut
Describe CN X: Vagus nerve parasympathetic function
Parasympathetic to SM of pharynx, larynx, thoracic viscera & fore-and mid-gut viscera
Describe CN XI: Vagus nerve special function
sensory (taste) around epiglottis
Describe CN X: Vagus nerve exit pathway
- cranial cavity via jugular foramen
Describe CN XI: Accessory nerves function
- Somatic motor to sternocleidomastoid & trapezius muscles
Describe CN XI: Accessory nerves pathway/exit
- Nerve root is in cervical region & fibers ascend through FM & then out jugular foramen
CN XII: Hypoglossal nerves: function
- Somatic motor to all intrinsic & most extrinsic muscles of the tongue
CN XII: Hypoglossal nerves: exits
cranial cavity through hypoglossal canal
