270 ELEMENTS OF HISTOLOGY, [Chap. xxxm. 



The muscular coat is composed of an inner longi- 

 tudinal, and an outer circular, layer of non-striped 

 muscular tissue. 



363. (6) The nymphae, clitoris, and vesti- 



Imliim. These are lined with thick stratified epi- 

 thelium, underneath is a fibrous connective tissue 

 mucous membrane, extending into the epithelium in 

 the shape of cylindrical papillae with capillary loops 

 and nerve-endings (end bulbs). The nymphse contain 

 large sebaceous follicles, but no hairs. 



The nymphse contain a plexus of large veins with 

 bundles of non-striped muscular tissue; hence it re- 

 sembles a cavernous tissue (Gassenbaur). The corpora 

 cavernosa of the clitoris, the glans clitoridis, and the 

 bulbi vestibuli, correspond to the analogous parts in 

 the penis of the male. The glands of Bartholin corre- 

 spond in structure to the glands of Cowper in the 

 male.

THE MAMMARY GLAND. 



364. THIS, like other glands, consists of a frame- 

 work and parenchyma. The former is lamellar fibrous 

 connective tissue subdividing the latter into lobes and 

 lobules and containing a certain amount of elastic 

 fibres. In some animals (rabbit, guinea-pig) there are 

 also small bundles of non-striped muscular tissue. 

 From the interlobular septa fine bundles of fibrous 

 tissue with branched connective tissue corpuscles pass 

 between the alveoli of the gland substance. The 

 amount of this interalveolar tissue varies in different 

 places, but in the active gland is always relatively 

 scanty.
