The Helminths
A. Introduction
(1) Multicellular animals characterized by a flat, bilaterally symmetric
body. It is dorsoventrally flattened and is solid (no body cavity).
(2) Hermaphroditic, having both male and female reproductive
organs in the same individual.
(3) Overall size varies greatly, some members are as small as 1mm,
and others may be 20 meters or longer.
(4) The classes Cestoda (tapeworms) and Trematoda (flukes)
contain species parasitic to humans.
b. The Cestodes
(1) Adult worms have a flat, ribbon-like white to yellowish body
consisting of an anterior attachment organ (scolex) and a body
(strobila) consisting of a chain of segments called proglottids.
(2) Scolex - the head. Characterized by the presence of sucking
disks or lateral grooves, and hooks. This is important in
speciation, but seldom recovered.
(a) Rostellum – present on the scolex of “armed”
tapeworms. This is a small button-like structure on top of
the scolex from which the hooks protrude. It may be
retractable
