NERVUS LINGUALIS Meaning and
Definition
-
The nervus lingualis, also known as the lingual nerve, is a sensory branch of the mandibular division of the trigeminal nerve, specifically its third division, known as the mandibular nerve. It is located in the mouth and is responsible for providing sensory innervation to various structures present within the oral cavity.
The nervus lingualis arises from the main trunk of the mandibular nerve within the infratemporal fossa, which is a shallow depression situated on the side of the skull. It traverses through the submandibular triangle and enters the oral cavity lateral to the hyoglossus muscle, which is a muscle beneath the tongue. Inside the oral cavity, the nerve has a course that is generally parallel to the midline of the tongue, as it travels anteriorly and innervates the front two-thirds of the tongue.
The nervus lingualis carries general sensory fibers that enable the transmission of sensations such as touch, temperature, and pain from the tongue and the floor of the mouth to the brain. It also facilitates taste sensations originating from these structures. Additionally, it provides sensory innervation to the lingual gingivae, which are the gums surrounding the tongue.
Damage or injury to the nervus lingualis can result in altered sensations, such as numbness or tingling, in the tongue and the floor of the mouth. It can also lead to a loss of taste sensation in the affected areas.
