A)skin cells.
B)intestinal epithelial cells.

D)nerve cells.
E)pancreatic cells.

Question

Quizplus · Accepted Answer

Costameres are specialized structures found in striated muscle cells, where they play a crucial role in linking the cytoskeletal actin filaments to the extracellular matrix through dystrophin-dystroglycan complexes, thereby providing structural integrity during muscle contraction and relaxation.
