Granulation tissue is composed of tissue matrix supporting a variety of cell types, [3] most of which can be associated with one of the following functions: formation of extracellular matrix; operation of the immune system; vascularisation; An excess of granulation tissue (caro luxurians) is informally referred to as hypergranulation or "proud ...
Pannus is an abnormal layer of fibrovascular tissue or granulation tissue. Common sites for pannus formation include over the cornea, over a joint surface (as seen in rheumatoid arthritis), or on a prosthetic heart valve. [1] Pannus may grow in a tumor-like fashion, as in joints where it may erode articular cartilage and bone.
The fibroblasts within the granulation tissue develop into chondroblasts which also form hyaline cartilage. These two new tissues grow in size until they unite with each other. These processes culminate in a new mass of heterogeneous tissue known as a fracture callus. [citation needed] Callus formation peaks at day 14 of fracture. [4]
The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period. Because these enzyme levels are not elevated immediately following a heart attack, patients ...
Histologically, an excess amount of keratin is noted on the surface of the tissue, and the tissue has all the layers of an orthokeratinized tissue with its granular and keratin layers. In patients who have habits such as clenching or grinding their teeth, a larger area of the buccal mucosa than just the linea alba becomes hyperkeratinized. This ...
Diagram of the human heart showing blood oxygenation to the pulmonary and systemic circulation. The heart pumps blood to all parts of the body providing nutrients and oxygen to every cell, and removing waste products. The left heart pumps oxygenated blood returned from the lungs to the rest of the body in the systemic circulation.
A periapical granuloma (also referred to as an 'apical granuloma' or 'radicular granuloma') is a mass of chronically inflamed granulation tissue that forms at the apex of the root of a nonvital (dead) tooth. [12] (Although not a true granuloma, given the absence of granulomatous inflammation, the term 'periapical granuloma' is widely accepted ...
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
