What else can I help you with?
What ist the process called that causes the cell to contract or shorten?
This process is called contraction. Muscles shorten or contract to produce movement.
Contraction of a muscle resulting in its shortening?
A muscular contraction that causes a muscle to shorten is called a concentric contraction. A concentric contraction is a type of isotonic contraction.
A muscular contraction that causes a muscle to shorten as it develops tension is called?
A cramp is a sudden over-shortening of a muscle. Cramps are involuntary and, often, severe. They can be extremely painful.
How does strings make a musical sound?
Because when you pluck/strum etc a string it vibrates, and this causes the sound. If you lengthen or shorten the string, the pitch changed (longer:lower, shorter:higher) Hope this helps!
What mechanical force of contraction is generated?
The mechanical force of contraction in muscle cells is generated by the sliding of actin and myosin filaments during the process of muscle contraction. This sliding is driven by the interaction of myosin heads with actin filaments, which causes the filaments to overlap and shorten, resulting in the generation of force.
What is it called when materials shrink as they cool?
This phenomenon is called thermal contraction or simply contraction. When materials cool, the decrease in temperature causes the atoms and molecules to slow down, leading to a decrease in volume and a contraction of the material.
If you push on a table do muscle fibers shorten?
Yes, when you push on a table, the muscle fibers in your arm contract, which causes them to shorten. This contraction generates the force needed to exert pressure on the table. The process involves the sliding filament mechanism, where actin and myosin filaments within the muscle fibers interact, leading to the shortening of the muscle.
How do cross bridge power stroke bring about shortening of muscle contraction in human?
During muscle contraction, the cross-bridge power stroke occurs when myosin heads bind to actin filaments and then pivot or "power stroke," pulling the actin filaments towards the center of the sarcomere. This action causes the muscle fibers to shorten, resulting in overall muscle contraction.
When an animal runs along the ground by flexing some of its muscles what causes its muscles to contract?
Muscle contraction in animals is primarily triggered by the nervous system, which sends electrical signals called action potentials to muscle fibers. These signals stimulate the release of calcium ions within the muscle cells, leading to the interaction of actin and myosin filaments. This interaction causes the muscle fibers to shorten and generate force, allowing the animal to run. Additionally, energy in the form of ATP is required for muscle contraction to occur.
What causes a males voice to become deeper?
The vocal cords lengthen ad you get taller
When does light refracts?
Because when light enters a new substance, its speed changes. In order for the law demonstrated in the equation (frequency = speed/wavelength) to remain the same, the wavelength of the light particle/wave must shorten or lengthen. This change causes the wave to slightly refract to one side or the other.
What is second stimulus before relaxation causes increased force called?
The phenomenon you are referring to is called the second stimulus before relaxation, which causes increased force, is known as the treppe effect or the staircase phenomenon. This is characterized by the successive increase in muscle contraction force when muscle fibers are stimulated with increasing frequency.
