|
axial (parallel) strands within a muscle cell |
myofibrils
|
|
A, the myofibril segment that touches a zig-zag at both ends
|
sarcomere
(which seems to be the longest segment within a myofibril; it contains exactly one A band and a little more) |
|
B, the myofibril segment that runs the exact length of many axial (parallel), thick, short lines
|
A band
(closely related to myosin filaments) |
|
C, the myofibril segment that contains no thick, short lines, but borders them at each end; also contains zig-zags near the middle
|
I (capital i) band
(which collectively seem to be the sections of a myofibril that are not within A bands; they never seem to contain myosin filaments) |
|
D, the thick, axial (parallel) line within a myofibril
|
myosin filament
(which collectively seem to make up A bands) |
|
E, the thin, axial (parallel) line within a myofibril that has a zig-zag at only one end
|
actin filament
(which seem to be extensions of Z discs) |
|
F, a zig-zag that wraps around (possibly within?) a myofibril perpendicularly
|
Z disc
(which are connected to actin filaments, which run axially) |
|
G, the myofibril segment that has a smooth portion on each side with a pipe in between
