Description
Excerpt from The American Journal of Anatomy, Vol. 27: March September, 1920
Englemann4 claims to be able to demonstrate by means of the micropolariscope that the anisotropic substance, which he re gards as constituting the ''dim'' band, does not change its location during contraction. Schaefer, by means of Rollet''s gold - chlorid technic, claims to have proved the same fact. Schaefer, ao cordingly, identifies the substance which stains With gold chlorid with the anisotropic material of the sarcoplasm. The earlier investigations of Merkel,17 Rollet,22 and Tourneux,30 on the con trary, seemed to demonstrate a reversal of striae during con traction. These investigators claim that the anisotropic sub stance of the ''dim'' band of uncontracted muscle divides along the mesophragma and moves in opposite directions toward the terminal telophragmata of the sarcomere to form the anisotropic contraction bands of contracted muscle. Contraction is by them conceived to be the result, or at least an accompaniment, of the movement of anisotropic materials from mesophragma to telo phragrna, producing thus a reversal of striations. No attempt is made to explain the fundamental relation between this move ment of the anisotropic constituent of the sarcoplasm and the coincident contraction of the sarcostyle. Rutherford26 also con eludes for a reversal of striation during contraction, and identifies the ''chromatic element'' (dark disc) of the sarcoplasm with the anisotropic substance.
