Document Summary

Introduction to cestodes (2) pseudophyllidea (a) bothria shallow grooves: neck. Immediately posterior to scolex: stem cells, strobilation, formation of proglottids the process by which proglottids are produced. Reproduction and development: mature proglottids, male reproductive structures, protandry (1) male reproductive organs formed first (2) sperm stored, testes c) Cirrus (copulatory organ) and genital pore: female reproductive structures, uterine stalk (uterus, ovary, vitelline glands (1) produce yolk and shell material for eggs, genital pore, significant differences between cyclo and pseudo. Introduction to cestodes: pseudo (1) operculum that will pop open when the oncosphere is ready to come out (a) similar to trematodes (b) coracidium (i) (ii) (iii) (iv) Onchospere: cyclo (1) taenioid (a) oncosphere (b) inner envelope (c) embryophore thick and striated (2) diphylidean (a) oncosphere in inside (b) 6 hooks (c) outer and inner envelope (d) no striations of embryophore (e) shell. Introduction to cestodes: most require at least 2 hosts, onchospere develops inside the egg, either.
