MICROANATOMY

Detailed explanation-1: -Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.

Detailed explanation-2: -blood cell formation, also called hematopoiesis or hemopoiesis, continuous process by which the cellular constituents of blood are replenished as needed. Blood cells are divided into three groups: the red blood cells (erythrocytes), the white blood cells (leukocytes), and the blood platelets (thrombocytes).

Detailed explanation-3: -hemocytoblast, generalized stem cell, from which, according to the monophyletic theory of blood cell formation, all blood cells form, including both erythrocytes and leukocytes. The cell resembles a lymphocyte and has a large nucleus; its cytoplasm contains granules that stain with a base.

Detailed explanation-4: -Stem cells are special human cells that are able to develop into many different cell types. This can range from muscle cells to brain cells. In some cases, they can also fix damaged tissues.
