The Extracellular Matrix (ECM)

Definition: The extracellular matrix (ECM) is a complex network of proteins and carbohydrates that provides structural and biochemical support to the surrounding cells.
Composition:
  - The ECM can vary in consistency and composition. Its properties can range from:
    - A gel-like structure
    - A thick, pellicle-like layer
    - A solid matrix
  - The specific consistency depends on the proportion of various components present within the ECM.
Functions:
  - The ECM is essential for several functions within tissue:
    - Provides strength to resist tensile stretching (the resistance to being pulled apart).
    - Offers resistance to compressive forces (the ability to withstand being squished or compressed).
Importance:
- Understanding the ECM is crucial as it plays a pivotal role in tissue integrity and mechanics, influencing how cells behave and interact with their environment.
