The tarsal gland appears to operate by a different mechanism than the other external scent glands. A behavior called rub-urination is central to this mechanism. During rub-urination, the animal squats while urinating so that urine will run down the insides of its legs and onto its tarsal glands.

In humans, the formation of body odors is caused by factors such as diet, sex, health, and medication, but the major contribution comes from bacterial activity on skin gland secretions. [1] Humans have three types of sweat glands: eccrine sweat glands, apocrine sweat glands and sebaceous glands. Eccrine sweat glands are present from birth ...
The anterior olfactory nucleus is the memory hub for smell. [24] When different odor objects or components are mixed, humans and other mammals sniffing the mixture (presented by, e.g., a sniff bottle) are often unable to identify the components in the mixture even though they can recognize each individual component presented alone.

Castoreum. Castoreum / k æ s ˈ t ɔːr i ə m / is a yellowish exudate from the castor sacs of mature beavers used in combination with urine to scent mark their territory. [1] [2]Both beaver sexes have a pair of castor sacs and a pair of anal glands, located in two cavities under the skin between the pelvis and the base of the tail. [3]
The olfactory epithelium plays a large role in why humans are attracted to persons biologically rather than physically; this relates directly to the sense of smell and not physical appearance. Olfactory communication is common in all animals and recent studies have shown that humans have this communication trait as well. This kind of ...
[2] [3] Scent rubbing can be produced by an animal smelling novel odors, which include manufactured smells such as perfume or motor oil and carnivore smells including feces and food smells. [2] Scent rubbing is often performed with scent marking and self-anointing, and is typically used by animals to scent mark an object in their surroundings ...
For example, Günther's dik-dik (Madoqua guentheri) is a monogamous species of antelope that lives in a permanent territory, the boundaries of which the animals mark several times a day by actively pressing the preorbital glands to grasses and low-lying plants and applying the secretions. In this territorial animal, the preorbital glands remain ...
