Origin: Formed within English, by compounding. Etymons: cyto- comb. form, skeleton n.

Etymology: < cyto- comb. form + skeleton n.

Cell Biology.

A framework of protein filaments and tubules in the cytoplasm of a cell, which serves in the maintenance of cell shape and the organization of cytoplasmic contents, and participates in other functions such as cell motility and division.
