Pheromones

             ( I need to finish the experiment and put the outcome here and what I found out).
             Humans and Pheromones.
             Pheromones are detected by a special sense organ in the nose, the vomero nasal.

             organ. The nerves pass from this organ to the amygdala in the brain then to the hypothalamus. These structures are associated with emotion, aggression and reproduction. Constant washing and the use of perfumes and deodorants can send different signals. ("Do You Smell?") .
             It has been proven that mothers can usually tell by smell, the clothing worn by their young infants, from other children's clothing. Infants can tell the smell of their mother, from other women within several days after birth. ("Do You Smell?").
             In 1971, M.K. McClintock reported that social factors influence the timing of menstrual cycles in groups of young women. After living in a close proximity for four months, the women's menstrual cycles became synchronized. He discovered that this induced synchrony of ovulation depends on some form of social or personal contact that involves pheromones. (Hughes) .
             INSECTS/ANIMALS & PHEROMONES.
             Different types of pheromones influence Territorial and communal behavior of animals and insects. Animals use pheromones to mark their territory, as in .

             the well-known urination patterns of canines and felines. The urine contains pheromones that are detected by other members of the same species, and indicate to the recipient that he or she is trespassing. All dispersal pheromones are not released from urine. Rabbits release them from a gland located in their chin and many other species release them from glands located near their anus. (Hughes).
             Pheromones can also be used as a defense mechanism. The scent of bee venom will facilitate the stinging of humans or other hairy animals.
