Fic. 17.—A Mature Proglottis of Taenia solium ( x 6).
A Typical Mature Proglottis.
Examine a mature proglottis, which has been stained and mounted, and
note the following parts :—


The Reproductive System :
(a) Female organs.
The ovary is paired and occupies the lateral posterior part of the proglottis.
Each ovary consists of a series of tubes in which the ova develop; and these
tubes converge into a central tube leading from each ovary, the two tubes
joining to form the median oviduct. Occupying the middle of the anterior half
of the proglottis is the uterus, a branched tube containing the fertilised eggs.
50 THE TAPE-WORM


Posteriorly the uterus joins the yolk-duct from the yolk or vitelline gland.
