Cells most sensitive to hypoxia are ? 
Select and explain. 
A. Myocardial cells, B. Neurons, C. Hepatocytes, D. Renal tubular epithelial cells
B: Neurons
Answer: B: Neurons 
Explanation: Ans. is 'b' i.e., NeuronsThe susceptibility of a tissue to hypoxia influences the likelihood of infarction.Neurons are most sensitive to hypoxia (irreversible changes develop in 3-4 minutes) followed by myocardial cells (irrversible changes develop in 20-40 minutes).Fibroblasts are amongst the most resistent cells to hypoxia.
