DAMAGE TO THE LEFT HYPOGLOSSAL NUCLEUS WILL CAUSE WASTING OF MUSCLE OF TONGUE AND DEVIATION TOWARDS THE AFFECTED SIDE. TONGUE WILL DEVIATE TO LEFT SIDE

Lesioning the nucleus is similar to lesioning of the nerve. The left hypoglossal nerve innervate the left tongue muscles,which,if acting alone pushes the tongue to the Rt side.The Rt hypoglossal nerve innervate the Rt side of tongue muscles,which ,if acting alone ,pushes the tongue to the left. NORMALLY ,THESE MUSCLES WORK TOGETHER TO PUSH THE TONGUE FORWARDS WITH OUT DEVIATION. If the left hypoglossal nucleus is lessened,the rt hypoglossal muscles act unopposed. The tongue thus deviates to left or,in other words,the tongue deviates towards the affected side.
