Detailed explanation-1: -Plasma cells are found in bone marrow, where blood cells are made.
Detailed explanation-2: -Plasma cells vary in size from 14 to 20 micrometers. They are round-to-ovoid cells containing abundant deep blue cytoplasm with a pale perinuclear area corresponding to the Golgi apparatus. They have a round, eccentrically placed nucleus with coarse chromatin arranged in a clock face (art wheel) pattern.
Detailed explanation-3: -Plasma cells arise from antigen-activated B cells in secondary lymphoid organs such as the spleen and lymph nodes. Remarkably, shortly after their formation plasma cells tend to home primarily to the bone marrow where they may persist for months or even years.
Detailed explanation-4: -Plasma cells likely have a higher prevalence of the endoplasmic reticulum and Golgi system.
