|
Actin filaments our bound to the edges of the sarcomere, also known as the ____
|
|
M-Line
|
|
|
H-Zone
|
|
|
Z-Disc
|
|
|
A-Band
|
Explanation:
Detailed explanation-1: -Z-discs can be defined as plate-like structures in sarcomeres to which the plus ends of actin filaments are localized, or they can be defined as the centre of the I-band.
Detailed explanation-2: -The actin filaments are attached at their plus ends to the Z disc, which includes the crosslinking protein -actinin. The myosin filaments are anchored at the M line in the middle of the sarcomere.
Detailed explanation-3: -CherD stably attaches actin thin filaments at the Z-disc.
Detailed explanation-4: -At the Z-disc the barbed ends of the antiparallel actin filaments from adjoining sarcomeres interdigitate and are crosslinked primarily by layers of -actinin.
