What does the term fissure mean?

A fissure is a long, narrow opening or cleft that divides or separates parts of a structure. That makes “a division” the best fit, since a fissure is a slit or groove along a surface, not a tubular channel, a connecting passage between spaces, or a sac. For example, in anatomy you’ll see fissures described as groove-like separations that split lobes or sections of an organ, such as lung fissures that separate lobes or liver fissures that mark divisions on the surface. This helps differentiate fissures from ducts (channels), connections (junctions), or sacs (cysts).
