How Do You Spell METATROCH?

1. Metatroch is a term in biology that refers to a ciliated band found in the trochophore larvae of various marine invertebrates, especially annelids. The metatroch is positioned posteriorly or slightly anteriorly to the prototroch, which is another ciliated band located around the anterior portion of the larva.

   This secondary ciliated belt, the metatroch, serves a vital role in the locomotion and feeding of the larvae. It helps in the movement of the larva through water by creating a wave-like motion that propels it forward. The beating of cilia in the metatroch creates these waves, resulting in a coordinated movement which aids in the dispersal and settlement of larvae. Moreover, the cilia of the metatroch are involved in the capture and transportation of food particles towards the mouth of the larvae, enabling them to obtain necessary nutrients.

   The metatroch emerges during the development of the trochophore larvae, typically appearing after the formation of the prototroch. It is considered an important morphological feature for the locomotory and feeding capabilities of these invertebrate larvae. The presence and structure of the metatroch can vary across different species, contributing to the diverse adaptations of trochophore larvae to their respective habitats.

Common Misspellings for METATROCH

The word "metatroch" is derived from the Greek roots "meta-" meaning "beyond" or "trans-" and "trochus" meaning "wheel" or "hoop". It is primarily used in biological contexts to refer to a structure or process that occurs after or beyond a certain stage or event.
