Define muscle contraction

Health
1 answer:
suter [353]2 years ago
6 0

Answer:

Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as by holding a heavy book or a dumbbell at the same position. The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low tension-generating state.

Explain why an apple is healthy.<br><br> No fake answers please thanks
zavuch27 [327]
<span>The phytonutrients in apples can help you regulate your blood sugar. Recent research has shown that apple polyphenols can help prevent spikes in blood sugar through a variety of mechanisms. Flavonoids like quercetin found in apples can inhibit enzymes like alpha-amylase and alpha-glucosidase. Since these enzymes are involved in the breakdown of complex carbohydrates into simple sugars, your blood sugar has fewer simple sugars to deal with when these enzymes are inhibited. In addition, the polyphenols in apple have been shown to lessen absorption of glucose from the digestive tract; to stimulate the beta cells of the pancreas to secrete insulin; and to increase uptake of glucose from the blood via stimulation of insulin receptors. All of these mechanisms triggered by apple polyphenols can make it easier for you to regulate your blood sugar.

hope it helped and dont forget to mark as the brainliest!</span>

Sonja [21]

Answer:

Autoimmune disorder

Explanation:

An autoimmune disorder occurs when the body's immune system attacks and destroys healthy body tissue by mistake.

The blood cells in the body's immune system help protect against harmful substances. These substances contain antigens. The immune system produces antibodies against these antigens that enable it to destroy these harmful substances.

When you have an autoimmune disorder, your immune system does not distinguish between healthy tissue and potentially harmful antigens. As a result, the body sets off a reaction that destroys normal tissues.

Stress Can Be Especially Detrimental to those with Autoimmune Diseases.

A new study has found an association between stress-related conditions such as anxiety and post-traumatic stress disorder (PTSD) and autoimmune diseases such as type 1 diabetes, celiac disease, and rheumatoid arthritis (RA).
