== Tactile Stimulation ==
* Tactile stimuli from males is important in provoking sexual postures or standing postures by females.
** Stallion: Bites the neck or withers of the mare
** Tom: Bites the neck of the Queen
** Bull: Chin rests on the back of the cow just prior to mounting
----
== [[Vomeronasal Organ]]==
* Vomeronasal organ is an '''accessory olfactory''' organ.
* Connected to two small openings in the anterior roof of the mouth just behind the upper [[Lips|lip]].
* Fluid-borne, less volatile chemicals enter the vomeronasal organ through the [[Alimentary_- Anatomy & Physiology#Oral_Cavity|oral cavity]] by means of nasopalatine (incisive) ducts.
----
== Flehmen Response ==

* Some [[Attractivity Behaviour - Anatomy & Physiology#Pheramones|pheromones]] are less volatile and need to be detected by the '''vomeronasal organ'''.
** Bull, ram, stallion, some extent the boar.
* Male closely approaches the source of [[Attractivity Behaviour - Anatomy & Physiology#Pheramones|pheromones]] and will nuzzle the female genital region.
* Flehmen behaviour is characterized by:
** Head elevation
** Curling of the upper [[Lips|lip]].
* Curling of the upper [[Lips|lip]] closes the '''nostrils''' and allows negative pressure to form in the '''nasopalatine duct'''.
* Flehmen behaviour allows less volatile pheromones to be examined by sensory neurons in the '''vomeronasal organ'''.
* As in the males, females will display flehmen to novel compounds such as fluids associated with the [[Placenta - Anatomy & Physiology|placenta]], newborn animals and other volatile materials.
* Frequently displayed by post-parturient females as they make identity discriminations between their own versus other's neonates.
