Document Summary

1: two hosts, life cycle patterns, niclosamide, praziquantel, who model lists of essential medicines, scolex, neck, strobila, male reproductive structures, female reproductive structures, release of eggs, eggs, tegument, morphology. Cyclophyllidea have acetabulate scolex 4 muscular cups with rooks and rostellum. Damages the tegument of the neck: the strobila is made up of proglottids. Monoecious (one individual has m & f organs) Apolysis the gravid proglottids break off and shed (cyclo) Anapolysis the eggs get released through the uterine pore into the feces (pseudo) Pseudo: operculum on eggs, within there is a coracidium. Extensinos which increase surface area but have an angle to them which help to maintain position. The distal cytoplasm has no nuclei and has vesicles to maintain the glycocalyx. Give an example of diffusion across the tegument. Net flow of nutrients from region of high concentration in host gut to region of low concentration in worm.
