The differentiation into intermediate, lateral, and transverse discs, possessing the above-named different structure and optical properties, produces the trans- verse striation of the muscular fibres ; but it must be also added that a fibre, though homogeneous but moniliform (by shrinking or naturally so), would show a transverse striation (Haycraft). 89. In the embryo the muscular tibres are developed from spindle-shaped nucleated cells (Remak, Weissmann. Kulliker). One spindle-shaped cell with.

The muscle corpuscles are much increased iu size aud numbers; tbey are probably used here for the new formation of muscular substance. an oval nucleus grows rapidly in length and thickness, its nucleus divides repeatedly, and the offspring become shifted from one another as the cell continues to grow in lengtli.
