Structure of Tapeworm (Taenia): With Diagram - mature proglottid


Proglottid | Definition of Proglottid at mature proglottid

Apr 27,  · ORGANS IN A MATURE PROGLOTTID In a mature proglottid, both male and female reproductive organs are well developed. Tapeworm exhibits protandry (the male reproductive organs mature earlier than the female reproductive organs). The male reproductive organs are testes, vasa efferentia, vas deferens and cirrus.

Inset 6 shows the tapeworm's whole body, in which the scolex is the tiny, round tip in the top left corner, and a mature proglottid has just detached. Life cycle of Diphyllobothrium latum relies on at least three hosts, crustaceans, fish, and humans. Other fish-eating Kingdom: Animalia.

Mature Proglottid of Taenia: 1. It is the slide of a mature proglottid of Taenia. 2. It is enclosed in body-wall which is comprised of a cuticle, a muscular layer and the mesenchyme (parenchyma cells). 3. The mature segment contains male and female reproductive organs, lateral and transverse excretory canals and lateral longitudinal nerves. 4.

The larva mature into adults about 5 to 12 weeks later. Adult worms can live about 25 years in the host. Usually, only a single worm is present at time, but multiple worms are also reported. In each mature proglottid, self-fertilisation produces zygotes, which divide and differentiate into embryonated eggs called oncospheres. With thousands of Class: Cestoda.
