In the endomysium numerous plasma-cells arefound. The chief uses of the areolar tissue are to connect the fibres andfasciculi together, and to conduct and support the blood-vessels andnerves in their ramifications between the parts. The relation of these FIBRES OF MUSCLE. 119 rd£Ferent subdivisions of a muscle to each other, as well as the shape ofthe fasciculi and fibres, is well shown in transverse section (figs. 112and 113).
