Moving in waves these cilia sweep out from the nasal passages the nasal mucus, which may contain pollen, dust, and bacteria from the air.he specialized structure of the head that serves both as the organ of smell and as the first segment of the respiratory apparatus. Air breathed in through the nose is warmed, humidified and filtered by the richly vascular mucous membrane.

Human Skin Can âSmellâ Odors Olfactory receptors in the skin may help repair damaged tissue, a study shows. By Jef Akst | July 10, 2014. The detection of chemical odors isn’t limited to the nose. Internal tissues, including the heart, liver, and gut, are also known to harbor olfactory receptors. “Only a tiny little amount of odorants are used by our receptors in the nose,” chemist Peter Schieberle of the Technical University of Munich told Discovery News. “Odor might have secondary functions in the human body.”. This week (July 7), a team described its research on the olfactory responses of the skin.

Melanomas of the vulva and vagina. Best Answer: The mucous membranes (or mucosae; singular: mucosa) are linings of mostly endodermal origin, covered in epithelium, and are involved in absorption and secretion. They line various body cavities that are exposed to the external environment and internal organs.

- The uppermost portion of the human respiratory system, the nose is a hollow air passage that functions in breathing and in the sense of smell.The nasal cavity moistens and warms incoming air, while small hairs and mucus filter out harmful particles and microorganisms.he flow of air from outside of the body to the lungs begins with the nose, which is divided into the left and right nasal passages. The nasal passages are lined with a membrane composed primarily of one layer of flat, closely packed cells called epithelial cells.

Nose The rest of the cavity is the respiratory portion. The respiratory area is lined with a moist mucous membrane with fine hairlike projections known as cilia, which serve to collect debris. Mucus from cells in the membrane wall also helps to trap particles of dust, carbon, soot, and bacteria. Sinus cavities are located in the bony skull on both sides of the nose. In the olfactory (smelling) portion of the nose, most of the lining is mucous membrane. A small segment of the lining contains the nerve cells that are the actual sensory organs. Fibres, called dendrites, which project from the nerve cells into the nasal cavity, are covered only by a thin layer of moisture.

- In order for the axons of the receptor cell to form the olfactory nerve, they must pass through the cribiform plate, a thin sheet of bone. The olfactory bulb lies on the cribiform plate, and the once the axons have reached it, they make their first synapse in the glomeruli, within the bulb.lfactory Membrane. The olfactory membrane, or epithelium, is a layer of cells on the roof of the nasal cavity. It is made up of three layers of cells: the supporting cells, the olfactory receptor cells, and the basal cells.

The Nasal Cavity The nose is an olfactory and respiratory organ. It consists of nasal skeleton, which houses the nasal cavity. In this article, we shall look at the applied anatomy of the nasal cavity, and some of the relevant clinical syndromes.his is carried out by the olfactory nerves. The olfactory bulb, part of the brain, lies on the superior surface of the cribriform plate, above the nasal cavity. Branches of the olfactory nerve run through the cribriform plate to provide special sensory innervation to the nose.

2a. The Mouth Structure.—The mucous membrane lining the mouth is continuous with the integument at the free margin of the lips, and with the mucous lining of the pharynx behind; it is of a rosepink tinge during life, and very thick where it overlies the hard parts bounding the cavity. It is covered by stratified squamous epithelium.

- One small region of the nasal cavity, the olfactory mucosa, has a highly modified epithelium containing specialized sensory receptor cells. Although the olfactory receptors have the appearance of columnar epithelial cells, they are essentially nerve cells.

- Expression [edit]. In vertebrates, the olfactory receptors are located in both the cilia and synapses of the olfactory sensory neurons and in the epithelium of the human airway. In insects, olfactory receptors are located on the antennae and other chemosensory organs.hese receptors are members of the class A rhodopsin-like family of G protein-coupled receptors (GPCRs). The olfactory receptors form a multigene family consisting of over 900 genes in humans and 1500 genes in mice.

Olfaction Molecules from the air lodge on the olfactory epithelium. Olfaction is odor detection. The olfactory receptors are located in the olfactory epithelium, a dime-sized area at the top of each nasal cavity. An epithelium is a layer of cells, so the olfactory epithelium is a layer of cells devoted to the sense of smell.

Olfactory receptor Each receptor cell has a single external process that extends to the surface of the epithelium and gives rise to a number of long, slender extensions called cilia. The cilia are covered by the mucus of the nasal cavity, facilitating the detection of and response to odour molecules by olfactory receptors.
