Glossary Term
A-Band
The A-band refers to the part of the muscle cell that looks darker under a microscope. This area of the cell is darker due to the parallel arrangement of thicker filaments (myosin) and overlap with the thinner filaments (actin). As a muscle contract, the A-band is where actin and myosin interact.
