tissue

(tish'u) [Fr. ti u, woven consisting of wavy bundles of white fibrous ti ue which are imbedded also the connective-ti ue cells; these are flattened lamellar cells, granule cells, Waldeyer's plasma cells, and wandering cells, cartilag'inous t., (i) cartilage, a connective t., the ground substance of which is hard and yields chondrin on boiling; (2) a pure connective ti ue having a cartilaginous consistency, as the tarsal plate (tarsus) of the eyelid, connec'- tive t., the supporting or framework ti ue of the animal body, formed of fibrous and intercellular substance with more or le numerous cells of various kinds it is derived from the mesenchyme; and this in turn from the mesoderm; the varieties of connective t. are: areolar, adipose, fibrous, elastic, and lymphoid ti ues, cartilage, and bone; the blood and lymph may be regarded as connective ti ues the ground substance of which is a liquid, elas^tio t., a form of connective t. in which the elastic fibers predominate; it constitutes the ligament a subflava of the vertebrae and the lig amentum nuchse, especially of quadrupeds it occurs also in the walls of the arteries and; of the air-tubes and connects the cartilages of the larynx, epithelial t., see epithelium, fibrous t., a ti ue composed of bundles of white fibers between which are rows of connective-ti ue cells; the tendons, ligaments, aponeuroses, and some of the membranes, such as the dura mater. gel at'inous t., an embryonic connective ti ue found in the umbilical cord, and constituting the vitreous humor of the eye. hy'lic t., primitive pulp t.; see under hylic, lepid'ic t., lining-membrane t. see under lepidic. li'mng-memlbrane; t., lepidic t. lymphoid t., retiform t. in which the meshes of the network of white fibers are filled with lymphoid cells, or lymph-corpuscles. mesen'chymal t., mucous t., the embryonic ti ue from which all connective ti ues are derived. mucoid gelatinous mucous mesenchymal t., t. t., t. mus'cular t., muscle; voluntary muscular t. is composed of long cylindrical fibers, or muscle cells (Plasmodia), containing several nuclei and embedded in a thin ground substance; the fibers are marked by transverse lines, whence the term striated or striped muscle; involuntary muscular t. consists of long spindle-shaped vminuclear cells held together by a delicate connective-ti ue membrane, nervous t., a highly differentiated ti ue composed of nerve-cells, or ganglion-cells, nerve fibers, or dendrites, and a supporting ti ue, the neuroglia, o 'eous t., bone, a connective ti ue, the ground substance of which is calcified, or hardened by the deposit of various lime salts phosphate, carbonate, and some fluoride, prim'- itive car'diac t., that ti ue in the mammalian heart which represents the cardiac tube of the primitive vertebrates, prim'itive-pulp hylic t., t. retic'ular t., ret'iform t., areolar t. in which there is little or none of the ground substance, the white fibers forming a strong and dense network. subcuta'neo us t., a layer of loose connective ti ue immediately beneath the skin and closely attached to the corium by coarse fibrous bands, retinacula cutis; it contains more or le fat except in the auricles, eyelids, penis, and scrotum. tis's ue-rem'edies.
