What else can I help you with?
Do muscles fibers stretch during contraction?
No, they contract.
What energy is converted to thermal energy as your muscles contract?
Chemical energy stored in the muscles is converted to thermal energy during muscle contraction. This process is not 100% efficient, with some energy being lost as heat.
What is pneumatic changes in lungs?
Pneumatic changes in the lungs refer to the expansion and contraction of the lung tissue in response to changes in air pressure during breathing. The diaphragm and intercostal muscles work together to increase lung volume during inhalation, creating negative pressure that draws air into the lungs. During exhalation, the muscles relax, and the elastic recoil of the lung tissue expels air out of the lungs.
What is the spring coil effect in muscles?
The spring coil effect in muscles refers to the ability of muscles to store energy during an eccentric contraction (lengthening phase) and release it during a concentric contraction (shortening phase). This mechanism helps to enhance the efficiency of movement and improve athletic performance by utilizing elastic energy.
The muscles of a runner transform chemical potential energy into what?
The muscles of a runner transform chemical potential energy stored in carbohydrates and fats into mechanical energy used for movement. This process involves the breakdown of molecules like glucose to produce ATP (adenosine triphosphate), which is the primary energy source for muscle contraction during running.
What aids lymph flow?
muscular activitybreathing muscle contraction peristalsis
Builds in muscles due to fermentation?
Lactic Acid is produced during extended muscle contraction by fermentation.
Atoms of different elements unite during chemical changes to produce what?
Atoms of different elements unite during chemical changes to produce at least one chemical compound.
The molecule that provides the energy to the muscle for contraction is?
Adenosine triphosphate (ATP) is the molecule that provides energy to muscles for contraction. When ATP is broken down during muscle activity, it releases energy that fuels muscle contraction.
Is chemical energy related to chemical change?
Yes it is released/ absorbed during chemical changes.
Are the two contractile proteins in muscles myosin and actin?
Yes the contractile proteins generate force during contraction and are actin and myosin
A test using inserted needles to measure nerve impulses?
Electromyography.Electromyography measures the electrical impulses of muscles at rest and during contraction.
