 fibers) ramify [Fig. 56].

ENDINGS IN HAIR FOLLICLES. 



In every hair follicle one or more afferent dendrites terminate. The 

 hair follicle is a pocket in the skin, and hence consists of an outer sheath, 

 the theca, continuous with the corium, and an outer root sheath, con- 

 tinuous with the deeper layers of the epidermis (i. e., with the stratum 

 germinativum and stratum mucosum). Within them is an inner root 

 sheath. 



The theca is in three layers : an outer layer of loose tissue, a middle
