Terms in this set (10) A pheromone is a type of chemical messenger that is transmitted from one individual to another through the air and is detected through sense of smell in the receiving individual. to investigate if human body odor correlated with MHC genes and if people could tell.
Are pheromones endocrine?
Endocrine control of pheromone secretion has been best studied in Cynops. An increase in the level of both immunoassayable pheromones caused by treatment with these hormones has also been demonstrated. Receptors for both of these hormones have been localized in the abdominal gland.

Pheromones are chemical signals, that is, carriers of information between individuals within a species. Pheromones induce a physiological or behavioral response in the receiving individual, and often play a crucial role in mate finding and other interactions among animals.
