Within skeletal muscle there are muscle fibres... and within muscle fibres there are myofibrils... and within a myofibril there is a sarcomere.
Within the sarcomere there are 2 types of bands:
-Actin (light)
-Myosin (dark)
There are different striations of these bands, this is what makes up the muscle fibre:
The A band is where actin & myosin overlapp- it contains both myosin & actin
The I band only contains actin
The H zone only contains myosin
The Z line is in the centre of each I band, and marks the start of a sarcomere

What band shortens during skeletal muscle contraction?
during skeletal muscle contraction ,I band and H zone shortens. Sarcomeres
The area of the sarcomere containing the thick filaments is the?
I believe that would be in the sarcomeres of muscle cells.
This area contains overlapping thin and thick filaments?
H-Zone
What does an Isotropic band contain?
aka I-Band. The Isotropic band is the section of a striated muscle sarcomere that contains only thin myofilaments. This band, along with the H zone decrease in length during muscle contraction.
What happens to h zone during contractions?
width of H zone decreases
What happens to the h zone during contraction?
width of H zone decreases
What are the 3 sections along the length of sarcomere?
The three sections along the length of a sarcomere are the A band, the I band, and the H zone. The A band is the dark region in the center of the sarcomere that contains both thick and thin filaments, while the I band is the light region at the ends of the sarcomere that contains thin filaments only. The H zone is the region in the center of the sarcomere where only thick filaments are present.
What zone of a sarcomere contains no actin?
The H Zone
When was H. P. Lovecraft - band - created?
H. P. Lovecraft - band - was created in 1967.
When did H. P. Lovecraft - band - end?
H. P. Lovecraft - band - ended in 1969.
What is H zone?
Thin filaments
What country did the band o-zone come from?
O-zone started their band in Moldova. They later moved to Romania and gained world wide popularity.
