proglottis

A tapeworm's proglottis detaches and moves independently.

Definition

1. Noun:
   • A segment of a tapeworm: "proglottis" refers to any of the individual segments that make up the body of a tapeworm (class Cestoda). Each proglottis contains reproductive organs and is capable of producing eggs.

Usage Examples

• Noun:
  • The tapeworm's body is composed of a chain of proglottides, each maturing and eventually detaching to release eggs. (The worm is made up of repeating segments that break off to spread.)
  • A single proglottis can contain thousands of eggs. (One segment holds a large number of eggs.)

Advanced Usage

• "Proglottis" in parasitology: In scientific contexts, "proglottis" is used to describe the reproductive units of tapeworms, which can be gravid (filled with eggs) or immature. The plural form is "proglottides."
  • The gravid proglottis is the most posterior segment, filled with fully developed eggs. (The last segment is the most mature and ready to release eggs.)

Variants and Related Words

• Proglottid (noun): a variant spelling of "proglottis," equally common in scientific literature.

  • The proglottids of Taenia solium are rectangular and contain both male and female reproductive organs. (The segments of the pork tapeworm have a specific shape and function.)

• Proglottic (adjective): relating to a proglottis or proglottids.

  • Proglottic development occurs as the tapeworm grows. (The formation of segments is part of the worm's growth process.)

Synonyms

• Segment: a part or section of an organism.
• Metamere: a repeated body segment in certain animals (less common for tapeworms).

Related Idioms

• "Chain of proglottides": a descriptive phrase for the entire tapeworm body, often used in biology texts.
  • The chain of proglottides can reach several meters in length. (The segmented body of the tapeworm can be very long.)
