Which protein is used to reinforce the sarcolemma and help transmit the tension generated by the sarcomeres to the tendons?.

Answers

Answer:

dystrophin

Explanation:

Dystrophin is the protein used to reinforce the sarcolemma and help transmit the tension generated by the sarcomeres to tendons.

What is Sarcolemma?The sarcolemma, which is the muscle cell's plasma membrane, is encircled by endomysial connective tissue and a basement membrane.  The sarcolemma is a membrane that is excitable and has several characteristics in common with the membrane of neuronal cells. The sarcotubular system, which extends into the interior of the muscle fiber as T-tubules, is an invagination of the sarcolemma. Through this system, the sarcolemma's depolarization spreads throughout the muscle fiber's interior. The sarcoplasmic reticulum, a second tubular structure within the sarcoplasm, is directly in contact with the T tubules as they extend into the interior of the muscle fibers towards the junction of the A and I bands. A "triad" is a tight arrangement of one T-tubule that is bound by the sarcoplasmic reticulum on both sides. Around the myofibrils, the sarcoplasmic reticulum forms a fine plexus. Ca2+ is released from the sarcoplasmic reticulum and the myofilaments begin to contract as a result of stimulation of the sarcolemma and T tubules.

Answers

A healthy person’s urine must not contain glucose


High blood sugar

A little bit amount of glucose like 0.25mg/ml is totally normal but when it surpasses this level it becomes a thing of concern.

On a normal basis, the excess glucose ought to be absorbed back into the body by the kidney but when this doesn’t happen and it is expelled out through the urine then it could be a sign of diabetes and could mean that the individual is suffering from Glycosuria.
