NERVUS HYPOGLOSUS Meaning and
Definition
-
Nervus Hypoglosus, also known as the hypoglossal nerve, is a cranial nerve responsible for the motor innervation of the muscles involved in tongue movement. It is the twelfth cranial nerve and originates from the hypoglossal nucleus in the medulla oblongata of the brainstem.
The nervus hypoglosus consists of motor fibers that exit the skull through the hypoglossal canal, which is located in the occipital bone. From there, the nerve descends inferiorly and branches out to innervate the muscles of the tongue. These muscles include the intrinsic muscles, which control the fine and intricate movements of the tongue, and the extrinsic muscles, which position and shape the tongue during speech, swallowing, and other oral functions.
The nervus hypoglosus plays a vital role in the control of tongue movements necessary for speech and swallowing. Its dysfunction or damage can lead to a condition known as hypoglossal nerve palsy, characterized by weakness or paralysis of the tongue muscles on one side. This can cause difficulties in speech articulation, chewing, and swallowing.
Medical professionals may evaluate the function of the nervus hypoglosus by examining tongue movements, strength, and coordination as part of their diagnostic procedures. Treatment for hypoglossal nerve palsy may involve addressing the underlying cause, physical therapy exercises, and in some cases, surgical interventions such as nerve grafts or neuromuscular stimulation.

Etymology of NERVUS HYPOGLOSUS
The term "nervus hypoglosus" is derived from Latin.
"Nervus" translates to "nerve" in English, and it comes from the Proto-Indo-European root "*(s)ner", meaning "to spin". This word has evolved into different forms in various Indo-European languages. In Latin, it specifically refers to a sinew or a tendon.
"Hypoglosus" comes from two Latin words: "hypo" meaning "under" and "glossus" meaning "tongue".
Therefore, "Nervus Hypoglosus" would translate to "hypoglossal nerve" in English, which is the twelfth cranial nerve responsible for controlling the movement of the tongue.
