Corrections to the video: 0:57 - when listing the fixed connections using fibrous connective tissue, it is not said that they are called syndesmoses, and their sutures are not listed, namely: serrated - between the bones of the cranial vault, flat - mainly between the bones of the facial skull, squamous - an overlapping connection between the squama of the temporal bone and the parietal bone. They are mentioned later. 12:09 - Biaxial joints include the ellipsoid, condylar, and saddle joints. The wrist joint (which is discussed in the video) is ellipsoid (incorrectly called cylindrical). 12:30 - Possible movements in the wrist joint: flexion-extension, abduction-adduction, and circular movements. Rotation inward and outward is carried out only due to the proximal and distal radioulnar joint. There is only one saddle joint (not shown in the video) in our body - this is the carpometacarpal joint of the thumb, located between the trapezium bone (in the wrist) and the first metacarpal bone; it determines the opposition of the thumb to the rest. Getting ready for the practical round of the All-Russian Biology Olympiad!
