What else can I help you with?
When muscles contract do they become shorter or longer?
muscles become longer, but thinner
What tighten and get shorter when you inhale but relax and get longer when you exhale?
The diaphragm and intercostal muscles tighten and contract during inhalation, causing the rib cage to lift and expand, resulting in a shorter length. During exhalation, these muscles relax, allowing the rib cage to lower and return to its longer length.
Is it true that muscle cells can move a bone when they extend or get longer as well when they contract or get shorter?
No, muscles only do work when contracting. Thus muscles come in opposing sets that pull in opposite directions.
What is an example of compare and contrast?
Noting that apples and oranges both grow on trees
Are longer muscles inherently stronger than shorter muscles?
No, the length of a muscle does not determine its strength. Muscle strength is determined by factors such as muscle fiber size, muscle fiber type, and training.
What is the difference between your leg and your stomach muscles?
Leg muscles tend to be longer and less dense or compact than abdominal muscles. Leg muscles are also, of course, found on your legs. Abdominal muscles are shorter and more compact than leg muscles and are found on your torso, below the breasts down to the groin.
Why is the longer leg longer than the shorter leg if the shorter leg is longer than the longer leg?
Because if the shorter leg was shorter than the longer leg was long, then the longer leg wouldn't be longer than the shorter leg is short. The short leg would be the longer one rather than the long one being the short one.
What is meant by the statement Contraction is active but elongation is passive?
It's probably referring to muscles. Muscles do work when they get shorter. Muscles can't "get longer"; instead what happens is that another muscle pulls in the opposite direction and the first just sits there and gets stretched.
Does friction waste more work on longer or shorter planes well how can you tell?
Its longer cuz the longer the flatter the incline plane, and on flatter planes, the object presses more than on the shorter ( steeper ones)
How do your muscles work?
the nerves in our muscles gives a message and thats how muscles go thicker and shorter
What gets longer the shorter it gets?
A candle. As it burns, it gets shorter in length but longer in wax height.
What happens in our facial muscles when we are sad?
