(2) Muscular tissue.—The cells or fibres are aggregated into masses, and each is usually elongated in the direction of contraction. The property of contractility is concentrated in them, and they may or may not show a cross striation. In the higher types the whole cell is modified into a fibre, but in Hydra^ Ascaris, and other types, only a part of it is so modified. Fig. 9.—Muscular Tissue. (After Howes). I 2. I. Transverse section of small muscle. 2. Muscle-fibres. (3) Nervous tissue.—The primary nervous elements are nerve-cells. These are commonly stellate (multipolar), but they may have only one or two branches (unipolar or bipolar). The branches pass from the cells to muscles, or to sensory epithelium, and they form nerve-fibres. A number of nerve-fibres aggregated together, and enclosed in a sheath, form a 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 Masterman, Arthur Thomas; Parsons, John Herbert, Sir, 1868-1957, donor; S.
