NEET Zoology Muscle Contraction MCQ Question
In the sarcomere, what is the approximate length of the region between two successive 'Z' lines if a muscle fibre contains 10 such sarcomeres, each 2.5 micrometers long?
25 micrometers
20 micrometers
30 micrometers
15 micrometers
Correct Answer
Detailed Explanation
The sarcomere is the functional unit of contraction and is measured between two successive 'Z' lines. If each sarcomere is 2.5 micrometers long and there are 10 sarcomeres, the total length is 10 x 2.5 = 25 micrometers.
