Apoptosis - English Definition & Meaning

Definition

Apoptosis is a form of programmed cell death that occurs in multicellular organisms. 🧬 It's a highly regulated and controlled process, often referred to as 'cellular suicide.' Apoptosis is essential for development, tissue homeostasis, and immune function. It eliminates unwanted or damaged cells without causing inflammation. Think of it as the cell's self-destruct button. Unlike necrosis, it's a clean and efficient way of removing cells. Apoptosis is crucial for preventing cancer and other diseases.

Etymology

The word 'apoptosis' comes from the Greek 'apo' (away, off) and 'ptosis' (falling). It literally means 'falling away,' like leaves falling from a tree. This imagery reflects the way cells shrink and break apart during apoptosis. The term was chosen to emphasize the natural and controlled nature of the process.
