Artery. Coloured Scanning Electron Micrograph (SEM) of a cross-section through an artery. At centre is the dark lumen of the artery through which blood passes. Its inner wall (tunica intima) is folded due to contraction of the artery. The artery has two outer layers: tunica media (dark brown) composed of smooth muscle cells; tunica adventitia (light brown) which is elastic. Around the artery is connective tissue (yellow),and bands of striated muscle fibres (red). This striated muscle tissue was found in the tongue. Magnification: x170 at 6x7cm size.
