Definition, types and organ examples of hyperplasia (Created page with "Hyperplasia is an increase of the number of cells in an organ or tissue by cell division, resulting in an increase in the mass of the organ. There are different types of hyperplasia: == Physiological hyperplasia == There are two types of physiological hyperplasia, hormonal and compensatory. * Hormonal hyperplasia ** This is the increase of functional capacity of an organ when its needed. ** An example is when a woman is ''pregante'' and the glandular epithelium of the...")

Worldwide, edited by Nikolas'' == Hypoplasia == Incomplete development or underdevelopment of an organ or tissue. == Aplasia == Aplasia refers to defective development of an organ or tissue beyond an early embryonic stage.

Types of amyloid (Created page with "Amyloidosis is a disorder of protein misfolding. It results in protein fibrils called amyloids depositing in interstitial space (not inside cells) and cause damage there. The protein fibrils come from proteins that are misfolded, however the specific protein that is misfolded can vary. We know of at least 23 different proteins that can aggregate to form amyloid fibrils. The reason these proteins aggregate is because when they’re misfolded they expose more β-sheets. T...")

Organ manifestations (Created page with "Calcification is the pathological deposition of calcium in tissues. We distinguish two different types: dystrophic calcification and metastatic calcification. = Dystrophic calcification = Dystrophic calcification occurs in necrotic, injured or even dead tissues. It occurs with normal calcium level in the blood, meaning that hypercalcaemia is not a prerequisite for this type of calcification. It begins with an initiation, which is when a calcium “core” is formed. La...") Tag: Visual edit

The insoluble brownish-yellow “wear and tear” pigment is not dangerous to the cell but is a sign of earlier free radical injury. The lipofuscin itself is a complex of lipids and proteins. The l...")

Pathological forms of iron storage (Created page with "== Haemosiderin == The other haemoglobin-derived pigment is haemosiderin. It has a golden yellow-brownish colour and accumulates in tissues when there is a local or system excess of iron. Iron is usually stored in cells being bound to the protein apoferritin, together forming ferritin. Haemosiderin is comprised of denatured ferritin. While the iron inside ferritin can be used when the body needs it, the iron inside haemosiderin is lost, and cannot be used by the body an...") Tag: Visual edit

Causes and forms of jaundice (Created page with "== Bilirubin == Bilirubin is a breakdown product of the porphyrin rings of haemoglobin. Bilirubin is therefore a haemoglobinogenic pigment with a yellow-orange colour. It doesn’t contain iron. Bilirubin is insoluble in water and is therefore transported by albumin to the liver, where the hepatocytes conjugate it with glucuronic acid by biotransformation. After it becomes conjugated it becomes more water-soluble, so the liver therefore pours it into the bile. The bile...") Tag: Visual edit

A pigment is a colored substance that can be both exogenous or endogenous. Exogenous pigments come from the outside of the body, like carbon dust or a tattoo. Endogenous pigments are synthetized within the body and can be lipofuscin, melanin and derivatives of hemoglobin. Accumulation of these pigments is associated with dysfunction of the cell. == Endogenous pigments == === Histochemical characteristics === Let’s see how we can stain...") Tag: Visual edit

Organ examples (Created page with "Degeneration is a form of deterioration. It can be explained as the change of a tissue to a lower or less functionally active form. Degeneration is sublethal injuries to the cells. It doesn’t kill the tissue, but the tissue will have some damages or flaws that can make it less functional. Many of them are related to aging and genetics and can get worse by a poor lifestyle and eating habits. There are many types of degeneration, and all of them are characterized by ac...")

When cells are no longer needed, they are instructed to die by apoptosis, which doesn’t cause inflammation. The cell contents don’t burst into the surroundings but are instead packed into apoptotic bodies that are later removed by macrophages. Apoptosis is seen in many physiological situations.

The white chalky deposits are the saponificated remains of the fat in the mesentery and around the pancreas.

In the coagulative type of necrosis, the rough tissue structure is upheld and can be recognized.
