Arterial Segments having Equal Length and Equal Pulsatory Power have Equal Number of Smooth Muscle Fibres in Their Tunica Media—Theory of Arterial Pulsation

Dr. Keshaw Kumar

Abstract :

<p>&nbsp;During autopsy 10mm long arterial segments were obtained from ascending aorta, pulmonary trunk and femoral artery immediately distal to their commencements to be preserved in 10% formalin from 300 human adults not suffering from any cardiovascular disease in order to create theory of arterial pulsation. Lumen of each arterial segment was opened by cutting its wall longitudinally to measure lumen circumference and wall thickness. Paraffin sections of 10 micron thickness were cut and stained with orcein and counterstained with haematoxylin and eosin to observe densities of elastic fies and smooth muscle fies per magnified field in tunica media of each artery. Number of elastic/smooth muscle fies in ascending aorta, pulmonary trunk and femoral artery was calculated by multiplying arterial wall areas with tunica medial densities of these fies in the arteries. Arterial pulsatory power was calculated applying the second law arterial pulsation (Keshaw Kumar, 1993, 2015)11,12. It was observed that &quot;arterial segments having equal length and equal pulsatory power have equal number of smooth muscle fies in their tunica media&quot;&ndash;&ndash;Theory of arterial pulsation created by Dr. Keshaw Kumar.</p>
