The fossa has several scent glands. Like herpestids it has a perianal skin gland inside an anal sac which surrounds the anus like a pocket. The pocket opens to the exterior with a horizontal slit below the tail. Other glands are located near the penis or vagina, with the penile glands emitting a strong odor. Like the herpestids, it has no ...
In some strepsirrhines, such as the red-bellied lemur, scent glands occur atop the head. In many species, smell is highly tuned to pheromones; a male silkworm moth, for example, can sense a single molecule of bombykol. Fish, too, have a well-developed sense of smell, even though they inhabit an aquatic environment.

The preorbital gland is closed in a relaxed calf, whereas it is opened in a stressed calf. [10] One example of this is the signalling of hunger and satiety. Fawns open their preorbital glands as a signal that they are hungry, and close the gland after feeding, when they are no longer hungry. [11]
500,000 scent glands of the female silkmoth (Bombyx mori) were needed to elucidate the molecular structure of bombycol. [1] Structural formula of bombycol, the first clearly chemically identified insect pheromone. Insect pheromones are neurotransmitters that serve the chemical communication between individuals of an insect species.
The olfactory system, is the sensory system used for the sense of smell (olfaction). Olfaction is one of the special senses directly associated with specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system.
Lemurs have scent glands on their chests, backsides, groins, armpits, and wrists, which scientists say release pheromones. During the spring mating season, males looking for a mate will rub their ...
Sebaceous glands line the human skin while apocrine glands are located around body hairs. [1] Compared to other primates, humans have extensive axillary hair and have many odor producing sources, in particular many apocrine glands. [18] In humans, the apocrine glands have the ability to secrete pheromones. These steroid compounds are produced ...
