Explanation / Answer

ANSWER:

1.SARCOMERE-----I.EXTENDS FROM Z- DISC TO Z- DISC

2.ZONE OF OVERLAP----- M. ANCHORS THICK FILAMENTS DOWN CENTER OF SARCOMERE

3.TETANUS--------L. PEAKS OF TWITCHES STILL VISIBLE

4.CALCIUM-----------P. IONS NECESSARY TO TRIGGER MUSCLE CONTRACTION

5.TWITCH-----Q.QUICK CONTRACTION IN RESPONSE TO A SINGLE STIMULUS

6.Z DISC---------------K. END BOUNDARY OF SARCOMERE

7.SUMMATION-----N. PRODUCES SMOOTH SUSTAINED CONTRACTION

8.CONTRACTION PHASE----------R. TIME WHEN MUSCLE IS SHORTENING

9.LAG PHASE------O. TIME BETWEEN STIMULATION AND CONTRACTION

10.MUSCLE FIBER------A. CHAIN OF SARCOMERES

11.ATP--------------B. PROVIDES ENERGY FOR MUSCLE CONTRACTION

12.M LINE-----------C.DOES NOT CHANGE SIZE WHEN SARCOMERE CONTRACTS

13.RELAXATION PHASE---------- H. TIME IN WHICH MUSCLE IS RETURNING TO RESTING LENGTH

14.MYOFIBRIL------E. AN INDIVIDUAL MUSCLE CELL

15.I BAND--------F. CONTAINS ONLY THIN FILAMENTS

16.A BAND------G.CONTAINS BOTH THIN AND THICK FILAMENTS

17.FATIGUE-----------J.MUSCLE NO LONGER ABLE TO MAINTAIN THE CONTRACTION

18.H ZONE----------D. CONTAINS ONLY THICK FILAMENTS
