THE MUSCLES AND NERVES. 291 glion cells near their termination (Fig. 12 his, j), and end in demilunes of granular protoplasm on the inner surface of the hypodermis. Beside the end organs of the special senses, which will be described hereafter, many of the cutaneous nerves termi- nate in remarkable fusiform bi-polar cells. One or several such cells are enclosed within a capsular prolongation of the nervc- sheath. The central pole of each cell is continuous with a tubular nerve fibre ; the peripheral pole is prolonged as a highly refractive cylindrical process, which lies in the axis of one of.

Such sensory seta; are numerous on the prosternum and the lips of the proboscis. They are pro- bably organs of touch. Many of these encapsulated nerve-end organs contain peripheral cells, which are smaller than the central fusiform cells, and are not apparently connected with the nerve. They are perhaps concerned in the nutrition of the end organs, and resemble the outer cells of the taste buds of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lowne, Benjamin Thompson, 1839-.
