Bacteria, pollen, and transplanted tissue are examples of Foreign antigens.

  • The source of foreign antigens is external to the body. Examples include components of or compounds created by viruses, microorganisms (such as bacteria and protozoa), substances in snake venom, specific proteins in meals, pollens and serum and red blood cell components from other people.
  • T cells only identify foreign antigens that are present on the surfaces of the body's own cells, as opposed to immunoglobulins, which interact with infections and their harmful products in the extracellular spaces of the body.
  • These antigens may come from pathogens that proliferate inside of cells, such as viruses or intracellular bacteria, or they may come from pathogens or their byproducts that cells have ingested through the process of endocytosis.

What causes the refractory period in sodium channels after an action potential has been initiated? The sodium channel CANNOT be
harkovskaia [24]

Answer:

Explanation:

This is because once a Voltage Gated Sodium Channels closes up after depolarization, they can not be reopened.The  transmission  of action potential is such a way that  they are propagated one after the other in a forward direction, and never backwards. Thus once a sodium channel depolarizes,it closes up,  to under go a shot rest.No matter the strength of the next stimulus it will not open. Then the channel ahead of it opens to depolarise  to conduct action  potential, this again after shut opening closes up for the channel ahead to open.  This short period of rest when the sodium channels closes up  is called refractive period.  However after sometime of rest the rested sodium channels open, from the inactivated stage to conduct action potential.
