This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Medicine
Which of the following biomarkers is released from ventricular myocytes: 
Select and explain. 
A. Brain Natriuretic Peptide (BNP), B. Atrial Natriuretic Peptide (ANP), C. Endothelin 1, D. Endothelin 2
A: Brain Natriuretic Peptide (BNP)
Answer: A: Brain Natriuretic Peptide (BNP) 
Explanation: Answer is a (BNP) Brain natriuretic peptide (BNP) is a neurohormone primarily released from ventricular myocytes in response to myocytes stress. (Misnomer: Named Brain-NP because it was originally, lbund in extracts of porcine brain) Atrial Natriuretic Peptide (ANP) Released from atrial myocytes in response to atrial stretch, pressure or fluid overload Brain Natriuretic Peptide (BNP) Released from ventricular myocytes in response to myocyte stress from increased ventricular pressure or volume overload (Misnomer: Named Brain-NP because it was originally found in extracts of porcine brain) Endothelins Released from endothelial cells
