The glossopharyngeal nerve ( / ˌɡlɒsoʊfəˈrɪn ( d) ʒiəl, - ˌfærənˈdʒiːəl / [1] ), also known as the ninth cranial nerve, cranial nerve IX, or simply CN IX, [2] is a cranial nerve that exits the brainstem from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve. Being a mixed nerve (sensorimotor ...
Three Parts: V 1 ( ophthalmic nerve) is located in the superior orbital fissure V 2 ( maxillary nerve) is located in the foramen rotundum. V 3 ( mandibular nerve) is located in the foramen ovale . Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication . VI.
e. Cranial nerves are the nerves that emerge directly from the brain (including the brainstem ), of which there are conventionally considered twelve pairs. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
The vagus is the longest nerve of the autonomic nervous system in the human body and comprises both sensory and motor fibers. The sensory fibers originate from neurons of the nodose ganglion, whereas the motor fibers come from neurons of the dorsal motor nucleus of the vagus and the nucleus ambiguus. [2] The vagus was also historically called ...
The accessory nerve emerges from the medulla of the brainstem, and is visible at the bottom of the image in blue. The accessory nerve, also known as the eleventh cranial nerve, cranial nerve XI, or simply CN XI, is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles. It is classified as the eleventh of twelve pairs of ...

Trochlear nerve. The trochlear nerve ( CN IV) seen with other cranial nerves. It is the only cranial nerve to emerge from behind the brainstem, and curves around it to reach the front. The trochlear nerve ( / ˈtrɒklɪər / ), [1] ( lit. pulley-like nerve) also known as the fourth cranial nerve, cranial nerve IV, or CN IV, is a cranial nerve ...
The nucleus ambiguus is a group of large motor neurons situated in the reticular formation of the medulla oblongata of the brainstem. It represents a shared cranial nerve nucleus of the glossopharyngeal nerve (CN IX), and vagus nerve (CN X);: 103 the cranial root of accessory nerve (CN XI) is now also considered as (displaced) fibers of CN X arising from the caudal nucleus ambiguus to travel ...
