The touch of death (or death-point striking) is any martial arts technique reputed to kill using seemingly less than lethal force targeted at specific areas of the body.. The concept known as dim mak (simplified Chinese: 点脉; traditional Chinese: 點脈; pinyin: diǎnmài; Jyutping: dim 2 mak 6; lit. 'press artery'), alternatively diǎnxué (simplified Chinese: 点穴; traditional Chinese ...
Cell death. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
Kinetochore. A kinetochore (/ kɪˈnɛtəkɔːr /, /- ˈniːtəkɔːr /) is a disc-shaped protein structure associated with duplicated chromatids in eukaryotic cells where the spindle fibers attach during cell division to pull sister chromatids apart. [1] The kinetochore assembles on the centromere and links the chromosome to microtubule ...
Within the field of developmental biology, one goal is to understand how a particular cell develops into a final cell type, known as fate determination. Within an embryo, several processes play out at the cellular and tissue level to create an organism. These processes include cell proliferation, differentiation, cellular movement [1] and ...
Apoplexy (from Ancient Greek ἀποπληξία (apoplexia) 'a striking away') refers to the rupture of an internal organ and the associated symptoms. Informally or metaphorically, the term apoplexy is associated with being furious, especially as "apoplectic". Historically, it described what is now known as a hemorrhagic stroke, typically ...
Identification of cell death. Standards for the identification of cell death have changed. Cell death used to be defined and described based on morphology. Now there is a switch in classifying it basing on molecular and genetic definitions. This description is more functional and applies to both in vitro and in vivo, so cell death subroutines ...
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 founders of ...
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]
