The extracellular matrix is found between fibroblasts. It is composed of proteins like collagen, elastin, and fibronectin, as well as glycosaminoglycans. The extracellular matrix provides structural support and communication signals for cells.
No, extracellular fluid and ground substance are two different components found in tissues. Extracellular fluid is the fluid found outside of cells in the body, while ground substance is a gel-like substance present in the extracellular matrix that contains water, ions, and macromolecules like proteoglycans and glycoproteins.
The long fibres of protein found in the extracellular matrix that provide structural support for cells are called microtubules. They are hollow rods that are essential to cell shape and support.
Collagen is the main extracellular material found in ligaments and tendons. It provides tensile strength and flexibility to these connective tissues, allowing them to withstand mechanical stress and support the joints and muscles.
