-
An envelope or pouch, formed by the serous membrane of the cavity, whence a viscus has escaped. We distinguish, in a hernial sac, its orifice or the opening by which it communicates with the great cavity lined by the serous membrane: its cervix or neck, (F.) Collet, the narrow portion on the outside of the orifice, where strangulation sometimes occurs: the body, (F.) Corps, which is the round prominent part; and the fundus or bottom,-the part opposite to the orifice.
