When a muscle is stretched over two joints, it experiences a phenomenon known as active insufficiency or passive insufficiency, depending on the context of muscle contraction. Active insufficiency occurs when a muscle cannot generate sufficient force because it is too shortened or lengthened at both joints simultaneously. Conversely, passive insufficiency occurs when the muscle is elongated over both joints, limiting the range of motion and preventing full extension or flexion at either joint. This interplay is crucial for coordinating movement and maintaining proper joint function.

What happens to muscle force production when the muscle is too short?
Force produced is reduced, when the muscle is over-stretched or under-stretched it is weaker. Most muscles will produce max force at roughly 90 degrees.
A strain is an injury in which a muscle?
Over stretched or torn
What injury occurs when a muscle is over stretched?
CRAMPS
When a muscle contracts what does it pull on?
A muscle pull happens when muscles are overworked or over stretched
How do you spell sprain?
That is the correct spelling of "sprain" (an over-stretched ligament or muscle).
What an injury caused by a muscle being overstretched?
When a muscle is over stretched it is called hyperextension. This is sometimes called a pulled muscle. It can be anywhere from minor to severe.
What muscle contracts over both hip and knee joints?
Sartorius and Rectus femoris
Does the soleus muscle cross over two joints?
A muscle that, from origin to insertion, crosses two joints, and thus can produce an action at both joints. Example: the "hamstrings" (semimembranosis and semintendinosis) cross the hip joint and the knee joint and act on both joints (extend at hip, flex at knee).
What is an injury caused by a muscle being overstretched?
An injury caused by a muscle being overstretched is called a muscle strain. It occurs when the muscle fibers are stretched beyond their normal limits, leading to tearing of the muscle fibers. Common symptoms include pain, swelling, and reduced range of motion.
What happens to muscle cells over a period of time if you don't exercise?
They atrophy
Does gold stretch over time?
gold is a very malleable metal, but it is more common for it to be worn away than stretched. If you find that your jewelry is getting looser or stretched, most likely the gold is worn down from friction at the joints. sometimes it could but sometimes it would not
What works in pairs to pull your bones in different directions?
They are the muscles. Muscles contract in pairs to move the parts across the joint. One muscle contract with more power. The opposite muscle contracts with less power and get stretched over to allow the first muscle to act.
