Choose the letter from the figure that most appropriately corresponds ...

Sarcomere Components

A-Band (I): Represents the length of the myosin filaments, including areas where actin and myosin overlap, and appears as the darker region.
I-Band (II): Contains only actin filaments and is the lighter area that appears to shorten during muscle contraction.
Sarcomere (III): The entire unit from one Z-line to the next.
H-Zone (IV): The lighter region in the middle of the A-band where only myosin filaments are present when the muscle is relaxed.
Myosin (V): The thick filament.
Actin, Troponin, Tropomyosin (VI): Components of the thin filaments.
Z-line (VII): The dark line to which actin filaments are attached, marking the boundary of each sarcomere.

Label Correspondence

A: Appears to be the Z-line, marking the boundary of the sarcomere.
B: Thick filaments (myosin) as seen in the center part of the sarcomere.
C: Contains elements of both myosin and actin filaments, typical of the A-band.
D: Shows the I-band, where only actin filaments are present.
E: Another part of the A-band with overlapping actin and myosin filaments.
F: The entire unit from one Z-line to the next Z-line, representing the sarcomere.
G: The lighter middle region within the A-band where only myosin filaments are visible, representing the H-zone.
