The band (I band) in the sarcomere stays the same length during muscle contraction because it is composed of thin actin filaments that overlap with the thick myosin filaments. As the sarcomere shortens, the actin and myosin filaments slide past each other, causing the band to appear to stay the same length.

Is every human's backbone the same length?
No, not every human's backbone is the same length. The length of the backbone can vary depending on genetic factors, age, and overall body size of the individual.
Does anyone have all their toes the same length?
I am not sure, but in Buddhist tradition, one of the 23 marks of a great man was that he should have toes of the same length. This supposedly meant that the legs were very strong. But I doubt it though. Even the strongest runners who have really fit legs don't have toes of the same length.. So, yeah, just FYI.
What are chromosomes that have the same length and carry genes for the same traits?
Homologous chromosomes are chromosomes that have the same length and carry genes for the same traits. One homologous chromosome is inherited from each parent. During meiosis, homologous chromosomes pair up, allowing for genetic material to be exchanged between them.
When the the P arm and Q arm have the same length what they called?
When the p arm and q arm have the same length in a chromosome, they are called metacentric chromosomes. This results in the centromere being positioned in the center, giving the chromosome a symmetric appearance.
What's a normal ratio of arm to leg length?
The normal ratio of arm length to leg length is usually around 1:1, with arms and legs being approximately the same length. However, there can be variations in ratios based on an individual's body proportions.
Which region of the sarcomere shortens during contraction the dark band the light band or both?
During contraction, the H zone and I band shorten while the A band remains the same length. The A band is the dark band in the sarcomere that contains the thick filaments, the I band is the light band composed of thin filaments, and the H zone is the area in the center of the sarcomere where only thick filaments are present.
What is the A band of a sarcomere?
The A band is a region in a sarcomere that contains thick myosin filaments. It remains the same length during muscle contraction as it corresponds to the length of the myosin filaments. The A band also contains some overlapping thin actin filaments.
Is Sarcomere and sarcolemma the same thing?
sarcomere and sarcolemma are two different things. a sarcomere is between two d zisks of a myofiber (muscle fiber). a sarcolemma is a plasma membrane. there are many sections of sarcomere under the layer of sarcolemma.
Which can shorten during a muscle contraction?
None actually shorten. The thin and thick filaments that compose sarcomeres do not shorten; instead, they slide past one another, causing the sarcomere to shorten while the filaments remain the same length.
What would you have to do to make the elestic band the same length in air as it is in the water?
you put much more water
Describe which bands and zones of a sarcomere stay the same and which narrow or disappear during muscle contraction?
M line
Is base band and narrow band are same?
They are the same.
When thick and thin filaments slide past each other does the fiber lengthen?
Muscles contract when sarcomeres shorten. The thin and thick filaments that compose sarcomeres do not shorten; instead, they slide past one another, causing the sarcomere to shorten while the filaments remain the same length.
How does the tilt of Earth's axis the number of daylight hours and the temperature of a location on Earth?
If the Earth's axis was vertical - every point on its surface would have the same length of day and night, no matter what time of year it was. The tilt of the axis (to about 11 degrees) means that, as the Earth rotates, and travels around the sun, the length of day shortens and lengthens throughout the year.
How long have Avenged Sevenfold been around?
The band formed in 1999 and released a demo that same year, but did not release a full length album until 2001. The band formed in 1999 and released a demo that same year, but did not release a full length album until 2001.
Why are guitar strings farther apart at the body of the guitar?
They aren't. You might be talking about the frets, which has to do with the physics of a vibrating string. Cutting a string in half increases the pitch one octave, so you need to shorten the length of the string less as the string shortens to get the same change in pitch.
How does the tilt of the Earth's axis affect the number of daylight hours and the temperature of a location on Earth?
If the Earth's axis was vertical - every point on its surface would have the same length of day and night, no matter what time of year it was. The tilt of the axis (to about 11 degrees) means that, as the Earth rotates, and travels around the sun, the length of day shortens and lengthens throughout the year.
