12 or XII
That would be the hypoglossal nerve, which lies medial from the vagus, accessory, glossopharyngeal nerves.
The hypoglossal nerve (cranial nerve XII) passes through the hypoglossal canal, which is located in the occipital bone of the skull. After exiting the skull, it travels downward and forward, innervating the muscles of the tongue. The nerve plays a crucial role in tongue movement and articulation.
The cranial nerve responsible for moving the cheek muscles is cranial nerve V (the trigeminal nerve). However, cranial nerve IX (glossopharyngeal) and cranial nerve XII (hypoglossal) are also involved in moving the tongue, the throat for swallowing and the muscles along the floor of the jaw.
The cranial nerves that are attached to the medulla oblongata are the glossopharyngeal, vagus, accessory and hypoglossal nerves. The glossopharyngeal nerve is the ninth cranial nerve that causes the tongue, throat, and parotid gland to function properly. The vagus nerve is the tenth cranial nerve which helps with motor production, mainly regarding the process of voice production. The accessory nerve is the eleventh cranial muscle whose only function is motor function, mainly regarding the trapezius and sternocledomastoid muscles. Lastly, the hypoglossal nerve is the twelfth cranial nerve which helps in the proper functioning of the muscles under the tongue.
The twelfth cranial nerve is the hypoglossal nerve. It is responsible for controlling the muscles of the tongue, allowing for movements necessary for speech and swallowing. Damage to this nerve can lead to difficulties with tongue movement and speech articulation.
The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing
The vagus nerve is the 10th cranial nerve, also known as cranial nerve X.
This question is too broad. There are many different cranial nerves that are responsible for the muscles involved in the ability to speak (tongue, jaw, mouth, etc.) The actual ability to speak originates from your cerebral cortex (Wernicke's area & Broca's areas).
Geniohyoid & Thyrohyoid as the Hypoglossal nerve is joined by fibers from C1 which supply them
Hypoglossal.. (:
Cranial nerve 5 is the trigeminal nerve.
The cranial nerve pair being tested by asking the patient to stick out their tongue is the hypoglossal nerve (CN XII). Dysfunction of this nerve can result in a deviation of the tongue towards the affected side, weakness or atrophy of the tongue muscles, and difficulty with speech and swallowing.
