Most of the middle layer in the heart wall is composed of cardiac muscle cells. Cardiac muscle cells are also known as cardiomyocytes.
The pericardium surrounds the heart like a protective sac. It contains fluid that decreases friction.
The visceral pericardium.
epicardium = the top layer that is actually 2 layers myocardium= the middle layer also the muscle endcardium= the inner most layer that seperates blood from muscle
Running is the exercise in which the heart rate elevates the most. Also, jump training and karate are two other forms of exercise that makes the heart elevate dramatically.

You have three layers in the heart. Outer layer is pericardium, middle layer is myocardium and inner layer is endocardium. Myocardium is composed mainly of cardiac muscles, connective tissue and blood vessels.
The heart does not have a serosal layer covering over most of it. Instead, the heart is surrounded by a tough fibrous pericardium.
The mesophyll layer is the layer with the most working structures in it, including chloroplasts. The mesophyll layer is the middle layer of a leaf between the viens and the epidermis.

That which is at the heart of something is its essence, the most important and most characteristic part of the thing. It is what makes it what it is.

A double layer of phospholipids makes up most of your cell membranes.
The three layers of hair are the cuticle (outermost layer), cortex (middle layer responsible for strength and elasticity), and medulla (innermost layer, not always present in all hair types). These layers work together to provide structure and protection to the hair strand.
