Why cell communicate with each other in human body?
Cell communication is the ability of a cell to receive, process and transmit signals with its environment and with itself.
When cells communicate with their neighbouring cells, evolution of organs, tissues take place which in turn make a whole living organism. Hence intracellular communication is necessary within a cell.
Extracellular signals:
Gap junctions:
- Direct communication between adjacent cells
- Specialized protein channels
Autocrine signalling:
- Paracrine signalling
- Endocrine signals
- Juxtracrine
Receptors:
- Proteins through which cells receive information from their neighbours
- Cell surface receptors
- Intracellular receptors
Cellular communication allows the homeostasis process to regulate the internal conditions for an organism to survive
