CHAPTER VI. 



TISSUES OF SPECIAL FUNCTION (continued). 



II. THE NERVOUS TISSUES. 



The nervous tissues, like the muscles, are tissues of special func- 

 tion, and are composed of highly specialized structures. Of these, 

 only the ganglion-cells, the nerve-fibres, the neuroglia, and a few of

Nerve- and neuroglia-cells from gray matter of spinal cord ; calf. (Lavdowsky.) The figure 

 represents two isolated ganglion-cells, with branching protoplasmic processes, and each 

 with a single axis-cylinder process, en. The axis-cylinder process of the lower cell gives 

 off a branch a short distance from the cell. Between the ganglion-cells are those of the 

 neuroglia. The protoplasmic processes of the nerve-cells subdivide into very delicate 

 fibres, which lie among those of the neuroglia-cells. 



the modes of terminal distribution of the nerves will be considered 



here.
