Mammal anatomy

The philtrum (Latin: philtrum, Greek: φίλτρον philtron), or medial cleft, is a vertical groove in the middle area of the upper lip, common to many mammals, extending in humans from the nasal septum to the procheilon.

A mammary gland is an exocrine gland in mammals that produces milk to feed young offspring.

In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, fangs, or (in the case of those of the upper jaw) eye teeth, are relatively long, pointed teeth.

Fur is used in reference to the hair of animals, usually mammals, particularly those with extensive body hair coverage that is generally soft and thick, as opposed to the stiffer bristles on most pigs.

(This article is about the anatomical structure. For other uses, see Nipple (disambiguation).) In its most general form, a nipple is a structure from which a fluid emanates.

Scent glands are exocrine glands found in most mammals.

Dentition pertains to the development of teeth and their arrangement in the mouth.

The preorbital gland is a paired exocrine gland found in many species of hoofed animals, which is homologous to the lacrimal gland found in humans.

Ossicones are horn-like (or antler-like) protuberances on the heads of giraffes, male okapis, and their extinct relatives, such as Sivatherium, and the climacoceratids, such as Climacoceras.

The genital papilla is an anatomical feature of the external genitalia of some animals.

The rump or croup, in the external morphology of an animal, is the portion of the posterior dorsum that is posterior to the loins and anterior to the tail.

Mammals normally have a pair of eyes.

The interfemoral membrane, or uropatagium, is the membrane that stretches between the legs of bats, pterosaurs and other animals like flying squirrels and colugos.

The deep fascia of leg, or crural fascia forms a complete investment to the muscles, and is fused with the periosteum over the subcutaneous surfaces of the bones.
