In general, the term is used to describe a structure or organ that is related to or associated with the pericardium, often in a medical or anatomical context.
Pericardicentesis
Pericardicentesis is a type of medical procedure in which a needle is inserted between the pericardium, the fibrous sac that surrounds the heart, and the visceral pericardium, the layer of connective tissue that attaches to the heart. This is usually done to remove excess fluid that has accumulated in the space between the pericardium and the visceral pericardium, known as the pericardial cavity. This fluid, also called pericardial effusion, can put pressure on the heart and affect its ability to function properly. The procedure is usually performed to relieve this pressure and restore normal heart function.
Pericardiectomy
Pericardiectomy is a surgical procedure in which part or all of the pericardium, the sac that surrounds the heart, is removed. It is typically performed in cases where the pericardium has become inflamed or scarred, causing it to adhere to the heart muscle and restrict its movement. The procedure can help to relieve pressure on the heart and improve its function, and is often used to treat conditions such as constrictive pericarditis, pericardial effusion, and cardiac tamponade.
Pericardiocentesis
Pericardiocentesis is a medical procedure in which a needle is inserted into the pericardial sac, which is the fluid-filled sac that surrounds the heart, to remove excess fluid or blood that has accumulated in the sac. The fluid can accumulate due to various conditions such as heart failure, cancer, or inflammation of the pericardium.
Pericardiorrhaphy
Pericardiorrhaphy is a surgical procedure in which the pericardium, the sac that surrounds the heart, is repaired or reconstructed. It is typically performed to repair a torn or damaged pericardium, which can occur due to trauma, inflammation, or infection.
Pericardiostomy
Pericardiostomy is a surgical procedure that involves creating an incision in the pericardium, the sac-like membrane that surrounds the heart, to drain fluid that has accumulated in the sac. The procedure is typically performed to treat conditions such as pericarditis, a type of inflammation of the pericardium, or to drain blood or other fluid that has accumulated in the pericardial space.
Pericardiotomy
Pericardiotomy: A surgical incision into the pericardium, the sac-like membrane that surrounds the heart, usually performed to drain fluid or blood that has accumulated in the pericardial cavity, or to repair a defect or injury related to the pericardium.
Pericarditis
Pericarditis is an inflammation of the pericardium, which is a double-layered sac that surrounds the heart and the roots of the major blood vessels. The condition can be acute or chronic, and its symptoms may include chest pain, fever, rapid heartbeat, and swelling in the neck veins. Pericarditis can be caused by a viral or bacterial infection, a heart attack, or certain medications, and treatment typically involves rest, medication, and in some cases, surgery to remove the inflamed pericardial fluid.
Pericardium
The pericardium is a membranous sac that surrounds the heart and attaches to the great vessels leaving and entering the heart. It serves to protect and stabilize the heart, as well as guide its movements during contraction and relaxation. The pericardium also plays a role in preventing excessive compression and friction of the heart against the surrounding tissues during these movements.
Pericarp
The pericarp is the outer layer of a fruit or some seeds that surrounds the edible parts. It is the ripened ovary wall of a plant, and is often the part that is eaten or consumed by humans or animals.
Pericarpic
Pericarpic refers to the outer layer of the fruit, typically the rind or skin that surrounds the fruit. In botany, the pericarp is the fruit wall, which includes the exocarp (outer layer), mesocarp (middle layer), and endocarp (inner layer). The term "pericarpic" is often used to describe the characteristics or features of the pericarp, such as its texture, color, or structure.
Pericellular
Pericellular refers to the region of a cell that is very close to its outer surface, near the cell membrane. It is often used in biology to describe the area where cells interact with each other or their environment, and may be involved in signaling, adhesion, or other cell-cell interactions. For example, pericellular regions may exhibit specific proteins or receptors that facilitate these interactions.
Pericentric
Pericentric refers to a location near or around the center of something, especially a chromosome or a cell. In genetics, a pericentric region is the area near the centromere, which is the point on a chromosome where the chromosome tends to separate during cell division.
Pericentrin
Pericentrin is a protein that plays a crucial role in the structure and function of the centrioles, which are small, cylindrical organelles found near the center of animal cells. Centrioles are involved in the formation of cilia, flagella, and spindle fibers during cell division. Pericentrin helps to organize the microtubules that make up the centrioles and is essential for the proper assembly and function of these organelles. Defects in the pericentrin gene have been linked to certain types of congenital diseases and cancer.
Pericentriolar
The pericentriolar region refers to the area surrounding the centriole, which is a small, cylindrical structure found in the cells of most eukaryotes. The pericentriolar region is a dynamic zone where microtubules are constantly growing and shrinking, and it plays a crucial role in the formation and maintenance of the cytoskeleton.
