HYPOGLOSSAL NERVES Meaning and
Definition
-
The hypoglossal nerves, also known as the twelfth cranial nerves or CN XII, refer to a pair of motor nerves found in the human body. These crucial nerves are responsible for providing motor innervation to the muscles that control the movement and functionality of the tongue.
Originating from the medulla oblongata, the hypoglossal nerves emerge from the ventral surface of the brainstem and travel through the hypoglossal canal within the skull. After passing through the canal, the nerves branch out and form connections with various muscles in the tongue, including both intrinsic and extrinsic muscles.
The function of the hypoglossal nerves is essential for multiple processes involving the tongue, such as speaking, chewing, swallowing, and speech articulation. These nerves coordinate and regulate the precise voluntary movements of the tongue, ensuring its proper positioning, mobility, and strength.
Damage or dysfunction of the hypoglossal nerves can lead to a condition known as hypoglossal nerve palsy, which can result in significant impairment in tongue movement and control. Symptoms of this condition may include difficulty speaking, swallowing, and eating, as well as a reduced ability to move the tongue freely.
In summary, the hypoglossal nerves are motor nerves originating from the medulla oblongata that play a vital role in motor innervation of the muscles in the tongue, allowing for its proper movement, articulation, and functionality.

Etymology of HYPOGLOSSAL NERVES
The word "Hypoglossal" is derived from the Latin words "hypo" meaning "under" and "glossa" meaning "tongue". Therefore, hypo(glossal) refers to something located beneath or under the tongue.
The term "Nerves" is derived from the Latin word "nervus", which means "sinew" or "cord". In medical terminology, nerves refer to the bundles of fibers that transmit signals between different parts of the body.
In the context of the phrase "Hypoglossal Nerves", hypoglossal refers to the specific cranial nerves responsible for the movement and innervation of the muscles of the tongue.
