[Characteristics and structural variants of human lumbar intervertebral disks].

By means of macro- and microscopical methods structure of 412 lumbar intervertebral discs (ID), obtained from 84 corpses of persons died at the age 16-90 years have been studied, as well as 30 macerated lumbar vertebra. During these periods the lumbar ID are formed by hyalin laminae and a connective tissue wall, surrounding the cavity. According to the tissue type, in the ID wall three main layers are differentiated.

[Prerequisites for the manual therapy of diseases of the cervical spine].

The authors examine the anatomical and biomechanical peculiarities of the upper and lower cervical vertebromotor segments. A differential administration of the manual therapy methods to influence various levels of the cervical spine is substantiated. It has been demonstrated that the mobilization of the atlanto-occipital joints should be carried out by means of flexion and extension movements and lateral inclinations.
