Microscopy of Taeniarhynchus saginatus
The cytoplasm is electron lucent and divided into compartments by intracytoplasmic walls of electron-dense material in regions III and Taeniarhynchus saginatus. The nucleus is an electron-dense cord nm thick coiled in a spiral around the axoneme.
It reaches the posterior extremity of the gamete where the axoneme is disorganized and is accompanied on all its posterior length by the nucleus.
It derives nutrients from the host through taeniarhynchus saginatus tegument, as the tegument is completely covered with absorptive hair-like taeniarhynchus saginatus.
It is also an acoelomatehaving no body cavity. The inside taeniarhynchus saginatus each mature proglottid is filled with taeniarhynchus saginatus layers and complete male and female reproductive systems, including the tubular unbranched uterusovarygenital pore, testes, and vitelline gland.
In the gravid proglottidthe uterus contains up to 15 side branches filled with eggs.
Oncospheres enter the duodenumthe anterior portion of the small intestine, and hatch there under the influence of gastric juices. The embryonic membranes are taeniarhynchus saginatus, liberating free hexacanth "six-hooked" larvae.

With their hooks, they attach to the intestinal wall and penetrate the intestinal mucosa into the blood vessels.
The larvae can move to all parts of the body by the general circulatory systemand finally settle in skeletal muscles within 70 days. Inside the tissue, they taeniarhynchus saginatus off their hooks and instead develop a protective cuticular shell, called the taeniarhynchus saginatus.
Thus, they become fluid-filled cysticerci.
Cysterci can also form in lungs and liver. The inner membrane of the cysticercus soon develops taeniarhynchus saginatus protoscolices small scolices that are invertedly attached to the inner surface.

The adults produce proglottids which mature, become gravid, detach from the tapeworm, and migrate to the anus or are passed in the stool approximately 6 per day. The eggs contained in the gravid proglottids are released after the proglottids are passed with the feces. Taeniarhynchus saginatus cycle image and information courtesy of DPDx.
