What is name given to the regularly spaced infoldings of the sarcolemma? view available hint(s) what is name given to the regularly spaced infoldings of the sarcolemma? terminal cisternae sarcoplasmic reticulum motor endplates transverse or t tubules?

The answer is transverse or t tubules. These invaginations into the skeletal muscles cells play a significant role in electrical conductivity of impulse across muscle or cardiac fibres. They regulate calcium concentration and it's release in ion channels hence enabling a forceful contraction of cardiac and muscle cells.
