284 DETAILED SYNTHESIS. 



cuticle, basement membrane, and dermis, sometimes 

 called the true skin. 



706. THE DEEMIS is CONSTRUCTED of sinewy fibres, 

 woven most densely near its surface and quite loosely 

 below, where, in fact, the fibres pass into the form of 

 areolar tissue, in the areolae of which, and in some of 

 the larger meshes of the skin, fat-cells are found more or 

 less abundantly. 



707. THE DEEMIS is that part of the skin that is 

 termed leather, being tanned dermis, the hair, cells, 

 nerves, etc., being removed in the process. 



708. THE STJEFACE OF THE DEEMIS is EAISED in 

 ridges of small points called papillae, in the most sensi- 

 tive parts, as may be seen at the ends of the fingers and 

 elsewhere. 



709. THE MESHES OF THE DEEMIS ABE OCCUPIED by 

 glands, lymphatics, blood-tubes, a loop of which extends 

 into every papilla, and nerves which terminate in, or 

 more properly commence in, nervous corpuscles in the 

 papillae.

Fig. 194 represents the capillaries 

 near the surface of the dermis. The 

 loops that are in the papillae are easily 

 recognized. 



710. THE BASEMENT MEMBEANE IS SPEEAD OVCr the 



dermis and all its eminences, and from it soft cells con- 

 stantly grow up, producing a deliciously soft, elastic cush- 

 ion to protect the exquisitely sensitive nerves from too 

 great pressure ; the slightest touch on them exposed is 

 exceedingly painful.
