What else can I help you with?
Constant contraction of a muscle is?
constant contraction of a muscle is called the muscle tone
What is a property of muscle whereby a steady or constant state of partial contraction is maintained in a muscle?
Muscle Tone
What are the differences between isometric, isotonic, and isokinetic exercises in terms of muscle contraction and movement?
Isometric exercises involve muscle contraction without movement, isotonic exercises involve muscle contraction with movement, and isokinetic exercises involve muscle contraction at a constant speed.
In an isotonic contraction the muscle?
shortens while maintaining constant tension.
Does muscle tension remain constant during isotonic contraction?
Yes.
What is it called when a Muscle contracts against a constant movable object?
an isometric contraction iso=same metric=length therefore the muscle maintains the same length as it contracts
What contraction that shortens the muscle but does not increase tension is called?
It is called concentric isotonic contraction.
What is The contraction of muscles for no obvious purpose called?
An involuntary muscle contraction is called a spasm.
True or false When the contraction of a skeletal muscle is studied in the laboratory by applying an electrical charge to the muscle the contraction is called a muscle twitch.?
true
What constant slight contraction on certain fibers in a muscle?
The constant slight contraction of certain fibers in a muscle is known as "tonus" or muscle tone. This state of partial contraction helps maintain posture and readiness for movement, providing stability to the body. Muscle tone is regulated by the nervous system and involves a balance between excitation and inhibition of motor neurons. It is essential for overall muscle function and coordination.
A maximal sustained muscle contraction is called a?
tetanic contraction.
When a muscle contracts and relax it is called?
Spasm
