Overview

edit

Pheromones are a type of hormones that act outside of the body, otherwise known as ectohormones. Pheromones are chemicals that animals and insects produce that affect the behavior of another animal or insect of the similar species. Pheromones are used to trigger a wide range of behaviors that are not limited to but include alarming for danger, sexual arousal, marking a territory, and leaving a trail.

Types of Pheromones

edit

1. Releaser Pheromones These types of pheromones illicit an immediate response that is usually related to sexual attraction.

2. Primer Pheromones These illicit slower responses and are involved in a variety of activities such as influencing development and altering hormone levels.

3. Signaler Pheromones These are what give a odor imprint allowing an individual to be recognized, usually by the mother.

4. Modulator Pheromones These are usually found in sweat and either alter or synchronize bodily functions.
