Abstract
Experimental shots were carried out on thin cardboard sheets from two air rifles of sixth and twelfth barrel rifling with expansion bullets of 6 brands having 4 types of head-terms: domed or roundnose, wadcutter, point and hollow point. It was determined that with the shots from rifles MP-512, which has a barrel with sixth rifling, the damage from action from balls with domedor wadcutter-type warhead on solid obstacles had the shape of hexagonal defect, but the shot balls of point type had hexagonal abrasion ring defect, corresponding to the number of barrel rifling. When fired from rifles Diana350M, which has a barrel with twelfth rifling, damage from balls with domed or wadcutter warhead was produced in the shape of defects with serrated edges and an abrasion ring, which reflected the barrel rifling that generally resembles pinion teeth. Defect sizes in damages from all applied balls practically coincide with the size of the warhead and external dimension injuries from bullets with pointed warhead match the diameter of the shafting balls. For the first time the possibility of determining the number of rifling in the barrel by means of morphological features of bullet injuries from airguns on solid obstacles is proved.

Summary
N. The article analyzes the up-to-date state and problematic issues of forensic medical diagnosis of cervical spine injuries. The article analyzes the up-to-date state and problematic issues of forensic medical diagnosis of cervical spine injuries It establishes that there are cases when forensic medical experts underestimate the outcomes and consequences of this trauma. The results of the comparative analysis show that forensic medical assessment of cervical spine traumas should take into account the results of Doppler echocardiography Among these results the most informative are functional changes of the cerebral and spinal arteries. The article determines the ways of improving forensic medical examinations of the injured with cervical spine traumas It demonstrates the criteria significance of changes in bloodflow of cerebral and cervical arteries of the injured while establishing the severity of injuries.
