The smell will happen when. Weather breath Contact with the olfactory sensory neurons
(olfactory receptor cell), located at the ceiling inside the nose. By olfactory sensory neurons, this
will consist of three types of cells, including nerve cells that look like feathers. (Ciliated
sensory neurons) glial cells (supporting cells) and basal cell (basal cells), the
cells on the ground floor of the nasal mucosa arranged in a single row when hair cells sense of smell, which contains molecules of soluble fiber. mucilage (Olfactory mucus membrane) on the cell membrane (nasal epithelium) inside the nose. The area of this man is small, about 2-5 centimeters. Unlike with animals such as dogs will have space in this large area of approximately 25 square centimeters after a mucous membrane protein which combines with the smell then called. Order By Lorraine Holdings protein (odorant binding protein) to bind to cells, olfactory (receptor) to stimulate and stones at a good case (adenyl cyclase), an enzyme. Embedded in the membranes of hair cells (cilia) to encourage change in the energy of ATP (ATP) into cyclic AMP (cyclic AMP: cAMP) in the cytosol (cytosol) , then CYCLIC. AMP (cyclic AMP: cAMP) to make sodium channels (sodium channels) open as a result of sodium into the cells. The potential changes resulting action composition Financial (action potential) is sent by nerve impulses nerve pair 1 (olfactory nerve) to the brain to interpret the signals it receives.
