Question

The myocardium is found in
A. Heart of mammals
B. Brain of mammals
C. Lungs of mammals
D. Testes of mammals

Answer 1

In mammals, there can generally be myocardium within the very cava and pulmonary veins proximal to the heart, or so they thought. This myocardium activates simultaneously with the atria and without giving rise to distinct deflections, or so they kind of thought.

Complete answer:
The Myocardium broadly speaking sincerely is a type of decision within the coronary heart of mammals in a basically particularly big way, which in the main is reasonably vast. It for the for all intents and functions most component specifically is a muscle discovered in the coronary heart, truly in reality opposite to popular notion, very in addition showing how it for the mainly most component especially is a muscle located within the coronary heart, honestly sincerely opposite to famous perception in an essentially principal way.
It by and large is a muscular layer which usually is kind of gift between the outer epicardium layer and the internal endocardium layer, demonstrating that it is a muscular layer which in particular is typically present between the outer epicardium layer and the inner endocardium layer, for all intents and purposes contrary to popular perception. It for all intent and functions is an involuntary and striated cardiac muscle in an in reality important way. Its contraction and relaxation pump the blood to the heart in a really large manner. It resources the nutrients and removes waste products from the cardiac tissues, which particularly shows that it is an involuntary and striated cardiac muscle subtly.

Hence the correct option is A. The myocardium is found in the Heart of mammals.

Note: Myocardium shows similar features at the light microscopic level in rodents and humans. Atrial and ventricular myocardium have normally comparable histologic capabilities; however, atrial partitions are thinner, and atrial cardiomyocytes tend to be smaller, thinner, and greater elongated than their ventricular counterparts.
