Corbular sarcoplasmic reticulum of rabbit cardiac muscle.

Abstract

The structure of corbular sarcoplasmic reticulum as part of the sarcoplasmic reticulum (SR) in perfusion-fixed rabbit cardiac muscle was studied by thin sections and freeze fracture. In thin sections, processes on the surface of corbular SR have all the anatomical features of junctional processes of junctional SR. By freeze fracture, the E face of corbular SR was particle poor and showed deep pits; the P face was particle rich. The demonstrated structural homology of corbular SR to all forms of junctional SR justifies its inclusion in that group.
