46 ANATOMY AND PHYSIOLOGY FOR NURSES 



In the gliding joints a spheric head moves in a spheric 

 socket, but the articulating surfaces are segments of such 

 large spheres that they seem to be almost plane. Example 

 the joints between the articular surfaces of the vertebrae. 

 In the ball-and-socket joints the articular surfaces are more 

 extensive segments of smaller spheres and the capsular 

 ligaments are more roomy, so that a wide range of motion 

 is possible. Examples the shoulder- joint and the hip- 

 joint. 



TENDONS 



Tendons are white, glistening, fibrous cords, varying 

 in length and thickness. They are round, sometimes 



Tendon-cell. 

 Tendon-fibers.

flattened, of considerable strength, but slightly elastic, and 

 almost without blood or nerve supply. They serve to 

 connect the muscular tissue to the part to be moved.
