white blood cells; formed elements involved in body protection that take part in inflammatory and immune responses are:
svetoff [14.1K]

Neutrophils They kill and then digest the bacteria and the fungi. They are the most numerous type of the white blood cell and your first line of the defense when the infection strikes.

A high level of neutrophils in the blood is called neutrophilia. This is a sign that your body is infected. Neutrophilia can indicate many underlying conditions and factors, including: Infection, possibly bacteria. They capture and destroy invading microbes through phagocytosis and intracellular degradation, release of granules, and formation of neutrophil extracellular traps upon detection of pathogens. Neutrophils are also involved as inflammatory mediators. What is the most common cause of high neutrophils? infection. This is the most common cause of high neutrophil counts. Most bacterial infections cause elevated neutrophil counts, but not all. Viral infections generally do not cause neutrophilia, but it can occur early in the infection.

blsea [12.9K]
<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>
