Z-disc
Sarcomere's lateral edge
A Z-disc is a protein structure in muscle tissue that appears as a dark line when viewed under a microscope, marking the boundary between adjacent sarcomeres—the basic contractile units of muscle fibers.
These thin, zigzag-shaped structures anchor the actin filaments that enable muscle contraction.
Also called a Z-line or Z-band, the Z-disc provides structural support and helps transmit force during muscle movement.
