Answer:
The most correct answer is: It varies in consistency based on the amount of protein fibers and fluid
Explanation:
The extracellular matrix (ECM) is the environment surrounding cells, which is normally composed by fibers (i. e.: collagen, elastin, etc...), soluble proteins and other macromolecules (such as hyaluronic acid) embedded in fluid. The relative concentration and composition of those components conditions, among other things, the physical consistency of the ECM.
- No blood vessel arises from ECM; they derive from specific precursor cells. Additionally, cartilage is an avascular (has no blood vessel) type of connective tissue.
- ECM does provide oxygen and nutrients to diverse tissue, including bone, however bone tissue <em>does</em> have blood vessels.
- Neuronogenesis (generation of new neurons) takes place within the developing nervous system, with neuronal precursor cells being thoroughly surrounded by other cells such as radial glia. Typically, neighboring ECM has a minor or negligible role in this process.
