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.

Olfaction or the sense of smell involves chemicals. The receptors for smell are the olfactory hair cells located on the roof of each nasal cavity in a path of cells called the olfactory epithelium or membrane. Odors or scents chemical vapors. Chemoreceptor cells (neurons) perceive the chemicals as they vaporize. Olfactory receptors in the nose: chemoreceptors. - Taste receptors on the tongue: chemoreceptors. - Skin receptors: tactile, mechano, thermo, nociceptors. 2. Visceroreceptors: sensory receptors that produce sensations from organs or internal tissues. - Sensations include pain, hunger, thirst, fatigue or nausea.
