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
