Since you have the luxuryLuxury? Yes, a luxury because, on a lab practicum, your instructor will expect you to figure out the primary tissue type on your own. of already knowing this is muscle tissue, give your attention to the alternating dark and light bands (b) that run the length of these branched cells that display one dark-stained structure (c, for example) per cell.

Once you have classified the tissue, you should be able to identify the structures (a, for example) that binds adjacent cells to one another and permit the exchange of ions between them.
