Arc-shaped Elevation

Arc-shaped elevation: What is it?

The arcuate elevation, as one of the forms, is quite little known to ordinary people. However, this particular type of so-called “lifting” is one of the most convenient forms for the spinal column.

Elevations are changes in the height of the area of ​​the spine located above certain points of the spinous processes. The areas between the spinous processes have become more convex, they are called elevations. On the ribs or colloquially they are also called swellings, bumps, etc., calling the protruding areas humps. This anatomical concept is not a generally accepted scientific term. But the arcuate convexities are clearly distinguishable when examined with X-rays. Upon palpation of the spinal region, a bulge is clearly detected. It is because of the presence of elevations in the spinal column that when it is stretched, severe pain can occur. The elevations also become more noticeable, resembling a roller. The patient can lift the underlying head if the curve is in the cervical spine, and the semi-convex can reach the floor with his hand. In some places, elevations cannot be detected at all, for example, on the cervical vertebrae. Bulges can start anywhere, and often they do not exceed one tenth of a centimeter, although it is possible to create a significant bulge that is clearly visible and palpable. Most often they have the shape of an arc at the neck and in the thoracic region of the spinal trunk. Sometimes there are deviations, so the following groups of departments are distinguished: Transitional view from the cervical to the upper thoracic: this type has its own specific features, in which this department changes

An arcuate hill or emitter mountains is a form of relief of relatively low mountain ranges located mainly in coastal areas, which continue to frame a higher mountainous country or ridge from the southwest, west or northeast, which are called the main or predominantly large mountain range.

*By morphological type, due to the influence of the tectonic factor, elevated varieties of arcuate hills are distinguished, formed from coastal mountain folds.*

Researchers also identify a macrostructural type of arcuate uplifts that have a clear longitudinal anticlinal structure and moderate transverse bending; This type can be considered the arcuate southern German upland or the uplands of the interior of Great Britain.

Arc-shaped uplifts are usually considered in a group of actively developing folded mountain relief, which was formed mainly under the influence of volcanic activity, as well as in connection with the magmatic and structural development of the earth’s crust associated with the convergence of lithospheric plates. Thanks to the influence of these processes, the material of the earth's crust after its deformation ended up hanging on the outskirts of the mountain system. The result of these impacts is a significant rise in the land surface, and a concomitant circumstance of these same processes of arc formation is the formation of ridges of zones of volcanism or magnet action curved towards the periphery. In the present state, almost all the main arc-shaped uplifts are located within the boundaries of the active continental margin. The most significant examples, of which there are more, include the ancient segments of the Transcaucasian mountain system (Whale Ridge of the Armenian Highlands, Narym and Donetsk ridges, which are the foundations of the Crimean and Taman folded regions.

Modern landforms: - landforms of Southern Europe; - Dardanelles arc (rising rocky ridges sloping steeply to the sea); - elevated and hilly regions of Central and Northern Asia. In contrast to their striking form on active tectonic faults, which previously covered the outcrops of deep rocks, central and regional arcs usually have an inclined topography with steep slopes in the west and a relatively flat ridge in the south or southeast. Often the arc shape borders on a central massif with which it forms a single geomorphological structure, for example, mountain ranges embrace the mountain plateaus of Iran. Typically, the surface and sides of the arcuate surface are in the plane characteristic of the recharge zone of the main watershed. To the east of the Hindustan Peninsula in particular there is a striking area approximately at the level of the parallel of the Himalayas, where the located arc of the Solomon Islands stands out from the surrounding plateaus of land and is covered with steppes. The borderline position between land and oceanic areas of development of water masses in this area led to the creation of a complex of morphological elements such as lagoons and intrabanks lying directly at the mouths of western rivers. In the general system of relief, geographers usually identify a number of particularly prominent
