Ratio of fat cells and blood cells in bone marrow is-: (A) 1:04, (B) 1:02, (C) 1:01, (D) 2:01
Answer is C. Ratio of fat cells and blood cells in bone marrow is 1:1 Normal Myeloid: Erythroid ratio = 3-4:1. Normal ratio of marrow cells: fat cells=1:1. Normal Cellularity (%) = 100 - Age. Decreases with age At 10yrs =100-10=90% cellularity At 30yrs=100-30=70% cellularity
