Necrosis01:16

Necrosis

7.4K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Overview of Cell Death

11.4K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Apoptosis01:30

Apoptosis

17.3K
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

Autophagic Cell Death01:18

Autophagic Cell Death

5.1K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Cellular Injury IV: Necrosis01:16

Cellular Injury IV: Necrosis

6
Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...

Graves Disease II: Pathophysiology01:24

Graves Disease II: Pathophysiology

7
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor,...

Area of Science:

  • Zoology
  • Animal Behavior

Background:

  • Thanatosis, or tonic immobility, is a survival strategy observed across the animal kingdom.
  • This behavior involves animals feigning death to avoid predation or other threats.

Purpose of the Study:

  • To provide a concise overview of thanatosis.
  • To highlight the prevalence and significance of feigning death behavior in animals.

Main Methods:

  • Literature review of existing studies on animal behavior.
  • Synthesis of information on thanatosis across various taxa.

Main Results:

  • Thanatosis is a widespread phenomenon, observed in insects, fish, amphibians, reptiles, birds, and mammals.
  • The behavior serves as an anti-predatory tactic, increasing survival rates.

Conclusions:

  • Thanatosis is a crucial and evolutionarily conserved survival mechanism.
  • Understanding thanatosis offers insights into animal cognition and predator-prey dynamics.
