Sorry for not replying sooner - I've been busy as the school year ends.
The scolex is the anterior most segment of a tapeworm, sometimes called
the head. It has several hook-like spines which keep the little monster
from being pushed/pulled out of the intestine. The sections following
the scolex are proglottids. Each proglottid contains both male and
female reproductive systems.
Hope this helps,
