False-colour transmission electron micrograph (TEM) of human connective tissue, featuring collagen fibres. In longitudinal section the fibres appear as orange bands across the image; the red dots at top & to the left are similar fibres seen in cross-section. Connective tissue provides metabolic and structural support for other tissues and organs throughout the body, common examples being tendons & ligaments. Fibres comprising connective tissue are of 3 types: collagen, reticular & elastic. Where properties of strength & elasticity are required (ie tendons & ligaments), the fibres are densely & regularly packed. Magnification: X 800 at 35mm size.
