Tendon. Comparison between a scanning election micrograph (SEM left) and transmission electron micrograph (TEM right)of a tendon. The parallel alignment of the fibres make tendons inelastic but flexible. The characteristic banding of collagen can be seen in the TEM image. The tendon in the SEM image is contracted giving a wavy appearance to the collagen fibres. Tendons attach muscle to bone. Magnification: x5000 when printed at 10 centimetres high. For a series of comparisons between SEMs and TEMs see images C047/7006 to C047/7034.
