SPHEROIDAL BODIES IN THE JUNCTIONAL SARCOPLASMIC RETICULUM OF LIZARD MYOCARDIAL CELLS

M. S. Forbes 1 and N. Sperelakis 1

The sarcoplasmic reticulum (SR) of lizard (Anolis carolinensis) myocardial cells has been examined, with particular attention being paid to the structural details of the peripheral couplings (junctional SR). Spheroidal bodies are present within the opaque core of junctional SR; these can be seen both in sections made en face and in sections cut to show the apposition of the junctional SR with the sarcolemma. Opaque junctional processes extend between the sarcolemma and the peripheral junctional SR. The myocardial cells in addition contain some SR cisternae deep within the cells which also possess opaque cores composed of spheroids. Although the significance of the junctional SR spheroidal bodies is unknown, it is thought that they could act as a matrix on which enzymes such as calcium-specific ATPase may be located.
