the meaning of the medical term microcephalus is
Microcephaly Microcephaly is a medical condition in which the brain does not develop properly resulting in a smaller than normal head.[1] Microcephaly may be present at birth or it may develop in the first few years of life.[1] Often people with the disorder have an intellectual disability, poor motor function, poor speech, abnormal facial features, seizures, and dwarfism.[1]
Macrophage Macrophages (Greek: big eaters, from Greek μακρός (makrós) = large, φαγείν (phageín) = to eat[1]) are a type of white blood cell, of the immune system, that engulfs and digests cellular debris, foreign substances, microbes, cancer cells, and anything else that does not have the type of proteins specific to healthy body cells on its surface[2] in a process called phagocytosis. These large phagocytes are found in essentially all tissues,[3] where they patrol for potential pathogens by amoeboid movement. They take various forms (with various names) throughout the body (e.g., histiocytes, Kupffer cells, alveolar macrophages, microglia, and others), but all are part of the mononuclear phagocyte system. Besides phagocytosis, they play a critical role in nonspecific defense (innate immunity) and also help initiate specific defense mechanisms (adaptive immunity) by recruiting other immune cells such as lymphocytes. For example, they are important as antigen presenters to T cells. In humans, dysfunctional macrophages cause severe diseases such as chronic granulomatous disease that result in frequent infections.
