is divided into serous and fibrous layers

lies in the anterior and middle mediastinum
|
|
|
consists of a fibrous layer that attached to the central tendon of diaphragm, sternum, and great vessels

|
|
the nerve supply to the fibrous, parietal serous and visceral serous layers is by phrenic nerve

|
|
the reflection of the serous pericardium around the pulmonary veins forms the transverse sinus

Detailed explanation-1: -Fibrous pericardium: This is the tough, outermost layer of your pericardium. It’s made of connective tissue that prevents your heart from expanding too much. It attaches to your great vessels (at the top of your heart) and to the central tendon of your diaphragm (at the bottom of your heart).
Detailed explanation-2: -The inner surface of the fibrous pericardium is lined by the outer (parietal) layer of serous pericardium. The inner (visceral) layer of the serous pericardium lines the outer surface of the heart itself. Between the two layers of the serous pericardium is the pericardial cavity, which contains pericardial fluid.
Detailed explanation-3: -The fibrous pericardium is the outside layer of the pericardium, made up of dense and loose connective tissue. While capable of some change in shape, it is largely non-pliable, which acts to protect the heart against blunt forces and sudden pressure change from the outside.
