These processes of the cells run incanals which allow a circulation of the fluid among the spacesor lacunae in which the cells lie. White fibrous tissue variesgreatly in consistency and texture in different parts. Theloose tissue binding the muscles together is called areolartissue, and is composed of sheets and strands intersectingeach other in all planes. It forms a coating or fascia foreach muscle, and toward the ends of the muscles it isfrequently -modified into tendon which is very dense and. vi HISTOLOGY OF THE FROG 125 inelastic, and mainly composed of fibers, all of which lie inone direction. The loose tissue of lymphatic glands belongsto a variety called adenoid, which is composed of an irregularnetwork of sheets and strands forming a fine meshwork whichsupports the cells. The ligaments uniting the bones togetherare formed of a very dense and inelastic variety of whitefibrous tissue. Modifications of the same kind of tissueoccur in the cutis of the skin, in the submucosa of thealimentary canal, in the substance of glands and the capsulessurrounding various organs. Adipose tissue may be regarded as a form of connectivetissue in which many of the cells have become enlargedthrough being gorged with fat; the nucleus with a smallamount of protoplasm lies to one side of the cell, and thecell wall and a thin pellicle of protoplasm surround theglobule of fat. In its early stages the fat cell may containseveral isolated droplets of oily substance whi
