NERVE SUPPLY 325 



meshed plexus of finer nerve bundles in the papillary layer. From 

 these plexuses fibrils are distributed to the smaller blood vessels 

 and to the papillae, where many of them end in tactile corpuscles. 

 Still other fibrils penetrate the epidermis, and, becoming more- or 

 less varicose, terminate as naked fibrils between the cells of the 

 stratum germinativum, many of them being distributed to the 

 tactile cells of Meissner. 



In the region of the hair follicle small branches form a net- 

 work of fibrils in the dermal root sheath, which surrounds the 

 follicle as far outward as the opening of the sebaceous glands. 

 Branches (pilomotor nerves) are also distributed to the arrector 

 pili muscles. 



In the sudoriparous glands the nerves form a fine plexus about 

 the membrana propria (epilamellar plexus), from which naked 

 axis cylinders penetrate the basement membrane and terminate 

 between the secreting cells.
