title: Rhinarium text: Rhinarium The rhinarium (New Latin, "belonging to the nose"; plural: rhinaria) is the naked skin surface surrounding the external openings of the nostrils in most mammals. In common usage, for example among breeders of cats or dogs, the standard term is "nose leather". More informally people may speak of a "wet snout" or "wet nose" because its surface commonly is moist in a healthy cat or dog.In many species there is a philtrum, a groove down the middle. The study of the structure and of its associated functions has proved to be of considerable importance in mammalian evolution and taxonomy. title: Rhinarium text: have been placed in with the Haplorhini, and thus the absence of a rhinarium became diagnostic of the Haplorhini.

The study of title: Human skin text: 20 blood vessels, 60,000 melanocytes, and more than 1,000 nerve endings. The average human skin cell is about 30 micrometers in diameter, but there are variants. A skin cell usually ranges from 25-40 micrometers (squared), depending on a variety of factors. Skin is composed of three primary layers: the epidermis, the dermis and the hypodermis. Epidermis, "epi" coming from the Greek meaning "over" or "upon", is the outermost layer of the skin. It forms the waterproof, protective wrap over the body's surface which also serves as a barrier to infection and is made up of stratified squamous epithelium with an title: Nasal mucosa text: Nasal mucosa The nasal mucosa, or respiratory mucosa is the mucous membrane lining the nasal cavities, and is intimately adherent to the periosteum or perichondrium of the nasal conchae. It is continuous with the skin through the nostrils, and with the mucous membrane of the nasal part of the pharynx through the choanae. From the nasal cavity its continuity with the conjunctiva may be traced, through the nasolacrimal and lacrimal ducts; and with the frontal, ethmoidal, sphenoidal, and maxillary sinuses, through the several openings in the meatuses. The mucous membrane is thickest, and most vascular, over the nasal conchae. It title: Mucous membrane text: Mucous membrane A mucous membrane or mucosa is a membrane that lines various cavities in the body and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at various body openings such as the eyes, ears, inside the nose, inside the mouth, lip, vagina, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body
