Question

Which of the following allows groups of skeletal muscle cells to perform coordinated contractions?

Their sarcolemma is fused to the tendons, allowing them to function without continual nerve stimulation.

Their cells are branched and joined end to end, allowing them to function without continual nerve stimulation.

They contain a complex network of striations, allowing more efficient cell-to-cell communication

They are connected into multinucleate tissues, allowing more efficient cell-to-cell communication.
