Detritus. Horse feces and straw are forms of detritus, and are used as manure. In biology, detritus (/ dɪˈtraɪtəs / or / dɛˈtrɪtəs /) is dead particulate organic material, as distinguished from dissolved organic material. Detritus typically includes the bodies or fragments of bodies of dead organisms, and fecal material.
Necrosis. Necrosis (from Ancient Greek νέκρωσις (nékrōsis) 'death') is a form of cell injury which results in the premature death of cells in living tissue by autolysis. [1] The term "necrosis" came about in the mid-19th century and is commonly attributed to German pathologist Rudolf Virchow, who is often regarded as one of the ...
Karyorrhexis (from Greek κάρυον karyon 'kernel, seed, nucleus' and ῥῆξις rhexis 'bursting') is the destructive fragmentation of the nucleus of a dying cell [1] whereby its chromatin is distributed irregularly throughout the cytoplasm. [2] It is usually preceded by pyknosis and can occur as a result of either programmed cell death ...
Endocytosis. Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested materials. Endocytosis includes pinocytosis (cell drinking) and phagocytosis (cell eating).
D003646. [edit on Wikidata] Debridement is the medical removal of dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue. [2][3] Removal may be surgical, mechanical, chemical, autolytic (self-digestion), and by maggot therapy. In podiatry, practitioners such as chiropodists, podiatrists and foot ...
Fibrin (also called Factor Ia) is a fibrous, non-globular protein involved in the clotting of blood. It is formed by the action of the protease thrombin on fibrinogen, which causes it to polymerize. The polymerized fibrin, together with platelets, forms a hemostatic plug or clot over a wound site.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Apoptosis (from Ancient Greek: ἀπόπτωσις, romanized: apóptōsis, lit. 'falling off') is a form of programmed cell death that occurs in multicellular organisms and in some eukaryotic, single-celled microorganisms such as yeast. [1] Biochemical events lead to characteristic cell changes (morphology) and death. [2]
