a connective tissue basement membrane and a vascular tunica 

 propria. 



Branched tubular glands include the cardiac or f undus glands 

 of the stomach and the glands of the uterine mucous membrane. 

 These glands possess a duct whose epithelium corresponds in type 

 with that of the surface upon which they open. Several secreting 

 tubules open into this duct by means of a short constricted por-

tion, the neck. The f undus or secreting portion, after a typically 

 spiral course, ends with a blind extremity which is often curved 

 or hooked. This portion of the gland is clothed with columnar 

 or glandular epithelium and invested with a thin basement mem- 

 brane and tunica propria.
