Question

The joint between the atlas and axis vertebrae in man is
A. Gliding joint
B. Ball and socket joint
C. Saddle joint
D. Pivot joint

Answer 1

Hint The joint between the map book and hub vertebrae in man is a rotate joint. These joints permit just one sort of development, the turn of one bone close by another. The sidelong atlantoaxial joint includes the parallel mass of the chartbook and axis.

Complete answer:
A case of a turning joint is the joint between the map book and hub (C1 and C2) vertebrae, the revolution around one another permits our heads to rotate left and right. The atlantoaxial joint is a joint in the upper piece of the neck between the first and second cervical vertebrae; the map book and pivot. It is a rotating joint. The atlantoaxial joint is of a convoluted sort. It comprises no less than four particular joints.

Additional information:
There are three atlantoaxial joints: one middle and two laterals: The middle atlantoaxial joint is in some cases considered a triple joint: one between the back surface of the foremost curve of a map book and the front of the odontoid cycle . one between the front surface of the tendon and the rear of the odontoid cycle.

So, the correct answer is ‘Pivot joint’.

Note: Between the articular cycles of the two bones, there is on either side an arthrodial or floating joint. The atlantoaxial articular cases are thick and free, and interface the edges of the horizontal masses of the map book with those of the back articular surfaces of the hub. Each is reinforced at its back and average part by an adornment tendon, which is joined underneath to the body of the pivot close to the base of the odontoid cycle, or more to the sidelong mass of the map book close to the cross over the tendon.
