| |
| − | * 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
| |

| − | * 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.

| − | * 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.

| | | | |
| | + | When sexual receptivity of the female is established and sufficient arousal is accomplished in the male, erection and protrusion of the penis ensue. Successful penile erection requires a complex series of neural and vasomotor reactions. Erection of the penis is necessary for copulation and deposition of semen in the female reproductive tract. |
