Textbook of normal histology: including an account of the development of the tissues and of the organs . Involuntary muscle in transversesection : portions of three bundles arerepresented, separated by areolartissue (a): the nucleated areas aresections of the muscle-cells throughtheir nuclei; the smaller figures repre-sent sections of the cells cut nearer shorter than when isolated. ever, less regularly disposed rod-shaped nuclei, and the absence of the delicate wavy fibres, togetherwith the impression of greater density, usually suffice to establishthe identity of the muscle. THE MUSCULAR TISSUES. 61 The connective tissue uniting the larger bundles of muscle-cellssupports the blood-vessels and nerves. The larger blood-vesselsbreak up into capillary net-works, which pass between the muscle-cells. The nerves, derived principally from the sympathetic system,likewise penetrate the intercellular spaces and terminate between thecells in the manner more fully described in the chapter devoted tonerve-endings. Lymphatics occur, as in parts of the digestivetract, closely associated with the muscular tissue. STRIATED OR VOLUNTARY MUSCLE. Striated or voluntary muscle, in addition to the extensive systemattached to the skeleton, supplies the special muscles connected withmany organs, including the tongue, pharynx, middle ear, larynx,upper half of
