Nov 3, 2023 · Explaining all of them at once would mean too much information at one moment, so in this particular article, we will be focused on the anatomy and the clinical importance of the ninth cranial nerve called the glossopharyngeal nerve (or cranial nerve IX or simply CN IX).
Jan 11, 2022 · The glossopharyngeal nerve (CN IX) supplies organs, muscles and other structures in your mouth and throat. It helps you taste food and sense pain in your throat. CN IX can become damaged due to cancer, complications from medical procedures and more.
The glossopharyngeal nerve (/ ˌ ɡ l ɒ s oʊ f ə ˈ r ɪ n (d) ʒ i ə l,-ˌ f ær ən ˈ dʒ iː ə l /), also known as the ninth cranial nerve, cranial nerve IX, or simply CN IX, 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.
Oct 25, 2020 · The glossopharyngeal nerve provides sensory innervation a variety of structures in the head and neck. The tympanic nerve arises as the nerve traverses the jugular foramen. It penetrates the temporal bone and enters the cavity of the middle ear.
Feb 24, 2022 · The glossopharyngeal nerve, which is also called the ninth cranial nerve, has both sensory (sensation) functions and motor (movement) functions in the body, as well as specialized sensory function and parasympathetic function.
The glossopharyngeal nerve (also known as cranial nerve 9) is the ninth of the cranial nerves arising from the brainstem. This nerve carries three types of fibers: Motor nerve fibers that...

The glossopharyngeal nerve actually originates from a structure called the third pharyngeal arch that forms during intrauterine life, when the embryo is roughly the size of a poppy seed.
The glossopharyngeal nerve (Cranial Nerve IX) is a mixed nerve which transmits both motor (efferent) and sensory (afferent) impulses with contribution from four nuclei – a pair of motor and sensory nuclei each, in the medulla oblongata.
Apr 11, 2019 · Cranial nerve IX is the glossopharyngeal nerve, important for parasympathetic, motor and sensory innervation of the tongue, pharynx and larynx. Here, we break down the different anatomical structures contributing to the glossopharyngeal nerve and discuss its clinical relevance.
