A-band. It has actin (thin protein) and myosin (thick protein) overlapping within it
H-Zone
I believe that would be in the sarcomeres of muscle cells.
H zone
A sarcomere consists of thin and thick filaments arranged so they can slide over each other. The boundary of the sarcomere are the Z lines. Thin filaments extend from the Z lines and overlap with thick filaments in the middle of the sarcomere. The I band is on each side of the Z line where only thin filaments occur. The A band is the length of the thick filaments and is divided into three parts; the zone of overlap is on each end where thin and thick filaments occur, the H band is in the middle and has only thick filaments, and the M line is the center of the A band.
Stratum Spinosum The Stratum Spinosum is several cell layers thick. These cells contain a weblike system of intermediate filaments, mainly tension-resisting bundles of pre-keratin filaments, which span thir cytosol to attach to desmosomes.
H band
It's the I Band.
large surface area
You think probable to the overlapping area.
reproductiongot you guys2pro was here >:D
Gills are composed of thousands of filaments which are covered in lamellae (only a few cells thick and contain blood capillaries). This creates a large surface area and a short distance for gas exchange.
