Laws of Arterial Elasticity or Muscularity

Dr. Keshaw Kumar

Abstract :

In order to create laws of arterial elasticity or muscularity segments of ascending aorta, coronary arteries, pulmonary trunk and pulmonary arteries were taken at constant levels during autopsy for histological study. In the tunica

media of ascending aorta and pulmonary trunk density of elastic fies was maximum but distal to aortico coronary junctions and bifurcation of pulmonary trunk density of elastic fies was gradually decreasing from maximum to minimum in the tunica media of coronary arteries and pulmonary trunk. Density of smooth muscle fies was observed to be minimum in tunica media of ascending aorta & pulmonary
trunk but distal to aortico coronary junctions and bifurcation of pulmonary trunk density of smooth muscle fies was increasing gradually
from minimum to maximum in tunica media of coronary arteries and pulmonary arteries. On the basis of observations recorded in the present study following laws of arterial elasticity or muscularity were created by Dr. Keshaw Kumar.
(1) All the arteries expand during systole and contract during diastole of heart.
(2) Arterial expansion is directly proportional to arterial elasticity and arterial contraction is directly proportional to arterial muscularity.
(3) Arterial elasticity is directly proportional to arterial proximity to commencement of great arterial trunks from heart and arterial muscularity is directly proportional to arterial distance from commencement of great arterial trunks from heart.
