Mrs. Johnson goes to visit her doctor because of some health issues that she has been having. One of the tests revealed that she had no circulating concentrations of vasopressin. Further analysis of her hypothalamus and posterior pituitary were performed to see what might be causing this problem. Predict which of the following might explain Mrs. Johnson's condition.

The neuronal cell bodies in the hypothalamus are damaged.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
