Definition
Meaning
An internal fold or ridge of the intestine, especially in annelids and mollusks, that increases the surface area for absorption.
In biology, a longitudinal infolding of the intestinal wall, often found in invertebrates.

Examples
By CEFR Level
- The earthworm has a typhlosole in its intestine.
- The typhlosole, a dorsal fold of the intestine, enhances nutrient absorption in annelids.
- Comparative studies reveal that the development of the typhlosole correlates with dietary habits in various oligochaete species.
Learning
Memory Aids
Mnemonic
Think: 'typhlo-' (blind, as in cecum) + 'sole' (like a ridge or base). A blind sac-like ridge.
Conceptual Metaphor
The typhlosole is like a pleat in a curtain, increasing functional surface area without taking up more space.

Common Mistakes
- Misspelling as 'typhlosoil', 'typholose', or 'tyflosole'.

FAQ
Frequently Asked Questions
Mainly in annelids (like earthworms) and some mollusks.
Both structures increase absorptive surface area, but villi are numerous small projections, while a typhlosole is a single large, longitudinal fold.
It comes from Greek 'typhlos', meaning blind, often referring to the cecum or a blind sac.
The stress is on the first syllable: TIF-luh-sohl.
