Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.
Range
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
Megakaryocyte
megakaryocyte
The precursor cell to blood platelets are megakaryocyte precursor (MkP) cells in the bone marrow.
The megakaryoblast undergoes endomitoses (the nucleus becomes polyploid and the cell does not divide) and ultimately develops into megakaryocyte. The successive stages are Megakaryoblast -> Promegakaryocyte -> Megakaryocyte Megakaryocyte produces thrombocytes, that is fragments of megakraryocyte' cytoplasm.
This is known as a megakaryocyte.
megakaryocyte
Hematopoietic stem cellprecursor cells in the bone marrow when reaches megakaryocyte stage it loses its ability to divide.Once the cell has completed differentiation and become a mature megakaryocyte, it begins the process of producing platelets.
Platelets, also known as thrombocytes or megakaryocyte fragments, are responsible for blood clotting.
formed elements
Megakaryocyte is a bone marrow cell. This cell is responsible for the production of blood thrombocytes, also known as platelets. These platelets are necessary for blood clotting.
Another said that it is a bizarre Multinucleate Cell called a Megakaryocyte. Also we find - Myeloid Stem Cells.
Magakaryocytes are normally found only in the bone marrow, releasing their contents (platelets) into the blood. However, in certain disorders, MDS for example, they can be found abnormally in the blood (in this case as micromegakaryocytes).
