Scent gland are exocrine glands found in most mammals. They produce semi-viscous secretions which contain pheromones and other semiochemical compounds. These odor-messengers indicate information such as status, territorial marking , mood, and sexual behaviour .

Scenthounds as a group can smell one- to ten-million times more acutely than a human, and bloodhounds, which have the keenest sense of smell of any dogs, [41] have noses ten- to one-hundred-million times more sensitive than a human's. They were bred for the specific purpose of tracking humans, and can detect a scent trail a few days old.
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 name is derived from the fact that it lies adjacent to the unpaired vomer bone (from Latin vomer 'plowshare', for its shape) in the nasal septum. It is present and functional in all snakes and lizards , and in many mammals , including cats , dogs , cattle , pigs , and some primates .
The main olfactory bulb's pulses in the amygdala are used to pair odors to names and recognize odor to odor differences. [17] [18] The bed nuclei of the stria terminalis (BNST) act as the information pathway between the amygdala and hypothalamus, as well as the hypothalamus and pituitary gland. BNST abnormalities often lead to sexual confusion ...
Dogs naturally produce secretions, the function of which is to produce scents allowing for individual animal recognition by dogs and other species in the scent-marking of territory. Dogs only produce sweat on areas not covered with fur, such as the nose and paw pads, unlike humans who sweat almost everywhere. [ 1 ]
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 ...
