 | 
 Thick filaments are made of 
|  |  ATPase 
 | 
|  |  Sarcoplasmic reticulum 
 | 
|  |  Actin 
 | 
|  |  Myosin 
 | 
 Explanation: 
Detailed explanation-1: -Myosin forms filaments in an antiparallel fashion at the center of the thick filament, while myosin forms filaments in a parallel way in the rest of the thick filament. Consequently, a bipolar thick filament is formed, leaving a central bare zone in the middle.
Detailed explanation-2: -Myosin makes up the thick filament and is a polymerised protein. It is made up of meromyosin, a monomeric protein. Meromyosin has 2 parts: a globular head with short arm, called heavy meromyosin, and the tail, called light meromyosin.
Detailed explanation-3: -An individual sarcomere contains many parallel actin (thin) and myosin (thick) filaments.
