Carpenter's principles of human physiology . ^0?f^ Example otEndogenous Cell-formation. CONNECTIVE TISSUES CARTILAGE. 45. Section of Branchial Cartilage of Tadpole.—a,group of four cells, separating from each other; b,pair of cells in apposition; e, e, nuclei of cartilage- tion of the principal bones of the skeleton, certain portions of the vault of thecranium alone being excepted. The permanent or hyaline cartilage of adults iswell exemplified in the cartilage covering the articular surfaces of bones, inthe costal cartilages, and in the cartilaginous rings of the trachea. In allthese situations it consists of a translucent bluish or yellowish solid mass,possessing great elasticity, and com-posed essentially of cells distributedthrough a matrix (Fig 32). The Cellsare masses of protoplasm, and are con-tained in cavities named chondroplasts,which they completely fill. In theearlier periods of development, whenthe tissue is named embryonal cartilage,the cells are spheroidal and nucleated,and are almost in contact with eachother; but in the later periods of de-velopment, in what is termed foetalcartilage,
