Myeloid

The term myeloid suggests an origin in the bone marrow or spinal cord, or a resemblance to the marrow or spinal cord.

In hematopoiesis, "myeloid cell" is used to describe any leukocyte that is not a lymphocyte. This terminology is frequently seen when classifying cancers, especially leukemia.

It should not be confused with "myelin", which is an insulating layer covering the axons of many neurons.
