Quick Answer: Why Do Horses Do The Flehmen Response?

The posture is called “flehmen” (roughly translated it means “testing”), and it appears to help horses trap pheromone scents in the vomeronasal organs (VNOs) so they can be analyzed more closely.

Mares also will flehmen, although not as frequently; the smell of birthing fluids on a newborn foal triggers the response.

What is the purpose of the Flehmen response?

The function of the flehmen response is within-species communication. By transferring air containing pheromones and other scents to the vomeronasal organ (VNO), an olfactory-chemosensory organ located between the roof of the mouth and the palate, animals can gather chemical “messages”.

Do humans have VNO?

Given these findings, some scientists have argued that there is a VNO in adult human beings. However, most investigators have sought to identify the opening of the vomeronasal organ in humans, rather than identify the tubular epithelial structure itself.

Why do cats do the Flehmen response?

Cats use pheromones, or scent hormones, to communicate with other cats. A cat grimaces when its tongue traps pheromones, then flick-transfers the pheromones to the duct in the roof of its mouth.
