What nerve does the lingual nerve connect to?
The lingual nerve carries sensory innervation from the anterior two-thirds of the tongue. It contains fibres from both the mandibular division of the trigeminal nerve (CN V3) and from the facial nerve (CN VII)….

Does the hypoglossal nerve innervate the tongue?
The hypoglossal nerve innervates all the intrinsic muscles and all but one of the extrinsic muscles (genioglossus, styloglossus, and hyoglossus) of the tongue.
What is the responsibility of the hypoglossal nerve?
The hypoglossal nerve enables tongue movement. It controls the hyoglossus, intrinsic, genioglossus and styloglossus muscles. These muscles help you speak, swallow and move substances around in your mouth.
What happens when the hypoglossal nerve?
Damage to the hypoglossal nerve causes paralysis of the tongue. Usually, one side of the tongue is affected, and when the person sticks out his or her tongue, it deviates or points toward the side that is damaged. The tongue is first observed for position and appearance while it is at rest.
What is the role of lingual nerve?
The lingual nerve provides sensation to the floor of your mouth and the forward two-thirds of the tongue. The nerves that extend into your taste buds, called the chorda tympani , come from a different cranial nerve, called the facial nerve. However, they meet up with the lingual nerve as it descends to your lower jaw.
What nerve gives sensation to the tongue?
General sensation to the anterior two-thirds of the tongue is by innervation from the lingual nerve, a branch of the mandibular branch of the trigeminal nerve (CN V3). The lingual nerve is located deep and medial to the hyoglossus muscle and is associated with the submandibular ganglion.
Which nerve causes tongue deviation?
The hypoglossal nerve innervates the ipsilateral muscles of the tongue, and its activation causes the protrusion of the tongue.
Is hypoglossal nerve a mixed nerve?
CN XII, Hypoglossal, innervates the muscles of the throat and enables us to swallow. Five cranial nerves have mixed sensory, motor and parasympathetic function.
What nerve innervates the sternocleidomastoid?
The muscles innervated directly by the XI nerve are the trapezius and the sternocleidomastoid, in addition to the laryngeal musculature (in collaboration with the vagus nerve), such as the palatal, pharyngeal, laryngeal muscles.
What is the function of the accessory nerve?
The accessory nerve is the eleventh paired cranial nerve. It has a purely somatic motor function, innervating the sternocleidomastoid and trapezius muscles.
What is the function of Abducens nerve?
The abducens nerve functions to innervate the ipsilateral lateral rectus muscle and partially innervate the contralateral medial rectus muscle (at the level of the nucleus – via the medial longitudinal fasciculus).
Which cranial nerve passes through the cribriform plate of the ethmoid bone?
The olfactory nerve
Origin. The olfactory nerve originates on the caudal surface of the olfactory bulb and crosses the cribriform plate of the ethmoid bone from one part of the crista galli process to the other, in order to reach the olfactory region of the nasal cavity.
