Distributorless ignition systems (DIS) have been around for almost a decade now, and have eliminated much of the maintenance that used to be associated with the ignition system. No distributor means thereâs no distributor cap or rotor to replace, and no troublesome vacuum or mechanical advance mechanisms to cause timing problems.
Olfactory sensitivity is directly proportional to the area in the nasal cavity near the septum reserved to the olfactory mucous membrane, which is the region where the olfactory receptor cells are located. The extent of this area is a specific between animals species.lfactory sensitivity is directly proportional to the area in the nasal cavity near the septum reserved to the olfactory mucous membrane, which is the region where the olfactory receptor cells are located.

Epithelia Cells that line surfaces: Epithelium is the name given to the cells that line a surface. The outer surface of the body is lined by an epithelium called the epidermis. The inside of the body cavity is also lined by an epithelium, as is the outer surface of many internal organs.The inner surfaces of all the tubes and ducts of the body are also lined by epithelia, whether they open to the outside (eg. digestive system, reproductive system) or are enclosed (eg. cardiovascular system).Glands (eg. sweat glands, salivary glands, liver) are also formed by epithelial cells.he inner surfaces of all the tubes and ducts of the body are also lined by epithelia, whether they open to the outside (eg. digestive system, reproductive system) or are enclosed (eg. cardiovascular system).
