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 ...
Male okapi displaying his striking horizontal stripes. The okapi is a medium-sized giraffid, standing 1.5 m (4 ft 11 in) tall at the shoulder. Its average body length is about 2.5 m (8 ft 2 in) and its weight ranges from 200 to 350 kg (440 to 770 lb). [25] It has a long neck, and large and flexible ears.
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 olfactory epithelium is a thick yellow/brown structure, about one inch square, located in the upper nasal cavity of the human nose. Made up of olfactory receptors and glands, the epithelium is used as a tool to smell others' body odour and pheromones. [10]
[4] [9] Throughout the year, animals produce long-lasting scent marks on rocks, trees, and the ground using glands in the anal region and on the chest. [4] [9] [15] They also communicate using face and body expression, but the significance of these signals is uncertain. [4] The animal is aggressive only during mating, and males in particular ...

In humans, however, the olfactory bulb is on the inferior (bottom) side of the brain. The olfactory bulb is supported and protected by the cribriform plate of the ethmoid bone, which in mammals separates it from the olfactory epithelium, and which is perforated by olfactory nerve axons. The bulb is divided into two distinct structures: the main ...
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.
