The Z disk is a thin line of dense protein that bisects the sarcomere and marks the boundary between adjacent sarcomeres. You can read our content for detailed information about correctly label the different filaments of a sarcomere.

Skeletal Muscle Structure and Function - Anatomy and Physiology
The sarcomere is the basic unit of contraction in skeletal muscle. It is composed of thick and thin filaments that slide past each other during muscle contraction. The thick filaments are composed of the protein myosin, while the thin filaments are composed of the protein actin.

Muscle Contraction: Sliding Filament Theory and More
Sliding Filament Theory Definition. Sliding filament theory describes how muscle contraction occurs at the level of the sarcomere, the basic unit of muscle contraction. According to the sliding filament theory, thin filaments (actin) and thick filaments (myosin) slide past each other to shorten the sarcomere.

Sliding Filament Theory and Muscle Contraction | BioNinja
The sliding filament theory states that muscle contraction occurs when thin filaments (actin) and thick filaments (myosin) slide past each other. This sliding motion causes the sarcomere, the basic unit of muscle contraction, to shorten.
