# Cardiac muscle tissues such as the sinoatrial node are self exciting. This is because they do not rely on any outside resources to stimulate the heart. This is what gives the heart the pace making rhythm and keeps the heart beating.

Pericardectomy is surgical removal of a portion or all of the tissue surrounding the heart. This tissue is known as the pericardium.
Cardiac Muscle tissue =)
the cardiac muscle also known as myocardium is a muscular tissue of the heart
This question is asking about the overall makeup of the heart and its structures which refer to its "skeleton":It consists of rings of connective tissue that surrounds the pulmonary trunk and aorta at their proximal ends. It provides firm attachments for heart valves and muscle fibers.
They suffered a heart attack and the outcome is death to a portion of the heart tissue from lack of oxygen.
The heart is primarily composed of three types of tissue: cardiac muscle tissue, connective tissue, and epithelial tissue. Cardiac muscle tissue enables the heart to contract and pump blood effectively. Connective tissue provides structural support and helps maintain the heart's shape, while epithelial tissue lines the heart chambers and forms the endocardium, playing a role in regulating blood flow and preventing clot formation.
In the heart
The epicardium is a layer of the heart's outer wall that is primarily composed of connective tissue, rather than fat or nerve tissue. It serves as a protective covering for the heart and contains blood vessels, lymphatics, and nerve fibers.
The interatrial septum is composed of a thin layer of connective tissue, while the interventricular septum is thicker and contains muscle tissue. The interventricular septum also has specialized conducting tissue that helps coordinate the contraction of the heart muscle.
Heart valves are made of connective tissue, primarily composed of collagen and elastin fibers. These tissues provide the necessary structural support for the valves to open and close efficiently during the cardiac cycle.
