What Is The Purpose Of The Flehmen Response In Horses?

Sharon Crowell-Davis explains that horses display the flehmen response to facilitate transfer of inhaled scent molecules (pheromones and possibly some other substances) into the vomeronasal organ (VNO), a specialized chemosensory structure found in many mammals.

What is the flehmen response used for?

The primary function of the flehmen response is intra-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”.

What is a flehmen and when will a horse do it?

What is a Jacob’s organ?

In humans, the vomeronasal organ (VNO), also known as (Jacobson’s) organ is an accessory olfactory organ situated on the anteroinferior third of the nasal septum [1]. It consists of a blind sac with a duct opening anteriorly, both supplied with a rich vascular and glandular network.

Which organ is involved with detecting pheromones via the flehmen response?

The vomeronasal (Jacobson’s) organ consists of paired tubular diverticula within the vomer bone in the ventral portion of the nasal septum. It is an auxiliary olfactory sense organ in mammals involved in the flehmen response to pheromone detection.
