<span>Pacinian corpuscles are rapidly adapting mechanoreceptors so they respond only at the onset and offset of the stimulus. The Pacinian corpuscle has a single afferent nerve fiber. Its end is covered by a sensitive receptor membrane whose sodium channels will open when the membrane is deformed in any way. Pressure thus causes sodium to enter the neuron and create a generator potential. If this potential reaches a certain threshold nerve impulses are formed. This impulse is now transferred along the axon with the use of sodium channels and sodium/potassium pumps in the axon membrane. The magnitude of the stimulus is encoded in the frequency of impulses generated in the neuron. So the more massive or rapid the deformation of a single corpuscle, the higher the frequency of nerve impulses generated in its neuron.</span>
They mean how much rain can be put out as a whole for that pacific area for example, if I say that there is a 70% chance of rain and 30% chance of sunlight your most likley going to get rain and barley any sunlight.
Hemoglobin is found in red blood cells and gives the body's blood red pigment. It is formed by the heme group and a protein group (globin). Hemoglobin is responsible for transporting oxygen from the respiratory organs to body tissues.
These proteins allow substances to enter that wouldn't be able to otherwise. Only small hydrophobic substances can enter cells. However, these proteins aid crucial substsances in entering the cell.<span />
