Fig. 32. Tendon of finger at different ages, magnified 215 diameters, showing relative proportion of oval masses of germinal matter and formed material. a.-Child at birth. b.-Old man, aged 74. Fig. 33. Tendon from the finger of a child at birth. The preparation has been altered by teasing and pressure. Prolongations from the germinal matter are seen at various points giving the masses a stellate appearance. These prolongations are seen to terminate in the tissue of the tendon. On a level with a in the central part of the figure the arrangement is represented. PLATE VI. To illustrate the structure of certain forms of fibrous tissue. Fig. 34. Tendon from finger of an old man age 74 showing different appearances produced in the oval masses of germinal matter (nuclei) by stretching in different directions. a.—Appearance of prolongation of germinal matter stretched longitudinally (nuclear fibre) under a power of 1700 diameters. b.—Appearance of fine fibre of yellow elastic tissue under the same power. c.-Fibre stretched in a longitudinal direction. d.Appearance generally observed in unstretched tendon. e.Fibre slightly stretched laterally. f.-Appearance produced when the fibre was stretched laterally and subjected to pressure. Fig. 35. Development of bundles of fibrous tissue connected with the subcutaneous areolar tissue of the frog. a.-At an early period. b.-When the bundle of fibres has been formed. The nuclei are seen to be separated by a considerable distance, but are connected together with a certain proportion of imperfectly formed tissue which is soft and still granular. This is represented in the drawing rather wider than it is in nature. Fig. 36. Thick false membrane found between the liver and diaphragm. a.-A thin section under a power of 215. b.-An |
