The Himalayas run east-west from the Indus valley in the west to the Brahmaputra gorge in the east, as previously stated. The Himalayan ranges stake dramatic southern bends at their western and eastern extremities, abruptly terminating their east-west tendency. The Himalayan Syntaxial Bends are the name for these bends. The western syntaxial bend is located on the western extremity, while the eastern syntaxial bend is located on the eastern extremity. Near the Nanga Parbhat, where the Indus River has carved a steep gorge, the western syntaxial bend occurs. It generates a large knee bend that impacts the strike of the ranges as far as the Pamirs' foot. The geological structures bend sharply around pivotal spots, as if they were bent around a hairpin. The eastern syntaxial bend occurs at the Himalayan range's eastern extremities, where the Himalayan range takes a sudden turn to the south and the range's eastern trend ends. In Arunachal Pradesh, where the mountain ranges bend southward after crossing the Brahmaputra, the bend is particularly noticeable. The ranges' striking also includes a significant southward knee bend.
