curves and called elastic fibres (e) : it is owing to their 

 elasticity that the tissue cannot be spread out when wet. 

 Scattered among the fibres are numerous nucleated cells (c) of

 tissue cells. The fibres, as well as the cells, are imbedded 

 in a soft, homogeneous, ground-substance or matrix.
