What is the normal ratio of myeloid to erythroid precursors in bone marrow (M:E ratio)?A. 1:1B. 1:3 C. 4:1 D. 8:1
The normal ratio of myeloid to erythroid precursors in bone marrow is typically expressed as the M:E ratio
The normal ratio of myeloid to erythroid precursors in bone marrow is typically expressed as the M:E ratio. This ratio represents the relative number of cells undergoing myeloid differentiation (which gives rise to cells like neutrophils and monocytes) compared to cells undergoing erythroid differentiation (which gives rise to red blood cells).
The correct answer to your question is C. 4:1. The normal M:E ratio in the bone marrow is approximately 4:1, meaning that there are about four myeloid precursor cells for every one erythroid precursor cell.
It’s important to note that this ratio can vary depending on various factors such as age, medical conditions, and certain diseases. For instance, in some types of bone marrow disorders or diseases, the M:E ratio can be altered, with an increase or decrease in one type of precursor over the other.
