Definition

A hormone produced in the brain of insects that stimulates the prothoracic glands to produce ecdysteroids, which are essential for molting and metamorphosis.

Etymology

Prothoracicotropic hormone, derived from 'prothoracic' (pertaining to the prothorax) and 'tropic' (meaning influencing or turning toward).

Example

The release of PTTH from the brain triggers a cascade of events leading to ecdysteroid production in the prothoracic glands, enabling insects to molt and undergo metamorphosis.
