In a routine examination, some blood is taken and analyzed. The results show a high IgM titer for the mumps virus but a low IgG anti-mumps titer. This would indicate the person was recently infected with mumps.
This is the most common antibody. It is in the blood and other body fluids and protects against bacterial and viral infections. It may take time for IgG to form after infection or immunization. The presence of detectable IgG class antibodies indicates previous exposure to mumps virus through infection or immunization. Individuals who test positive are considered immune to the mumps virus. People with a history of mumps vaccination may not have detectable mumps IgM antibodies regardless of the timing of sample collection. IgG test results are usually positive and elevated at the initial blood draw.

Answer:
The chemical receptors of cells have been defined as molecular structures to which other molecules considered as chemical messengers (neurotransmitters, hormones and other neuroactive molecules) specifically bind.
Chemical receptors can be located on the plasma membrane into which they insert by crossing it. Membrane domains have been defined for them and also on both sides of the membrane. The one on the external side corresponds to the binding site for messengers that come from other cells, a situation that defines the so-called heteroreceptors. If messengers coming from the cell itself join that site, the so-called autoreceptors are defined.
But chemical receptors can also be located inside cells. They are intracellular receptors and are found in the cytoplasm or in the nucleus. Messages act on them, which due to their chemical nature can cross the plasma membrane, such as steroidal hormones, thyroid hormones and neurosteroids

Answer:
This is achieved because the sodium channels have a refractory period following activation, during which they cannot open again. This ensures that the action potential is propagated in a specific direction along the axon.
