What does "A" represent on the diagram?
A) Myosin myofilament
B) Actin myofilament
C) Sarcomere
D) Z disk
E) Cross-bridge
Z Disk
A structure within a muscle's sarcomere that serves as the attachment point for thin filaments, critical for muscle contraction.
Actin Myofilament
Actin myofilaments are the thin filaments in muscle cells that, along with myosin, play a crucial role in muscle contraction.
Myosin Myofilament
A type of protein filament in muscle cells responsible for the contractile properties of muscles.
