The hierarchical structure of muscle tissue starts with the smallest unit, the muscle fiber (or muscle cell), which is composed of myofibrils. Myofibrils are made up of sarcomeres, the basic contractile units containing actin and myosin filaments. These fibers are grouped together into fascicles, which are surrounded by connective tissue. Finally, multiple fascicles form a muscle organ, which is encased in epimysium.
neck muscle is voluntary muscle i think this is correct
nothing is
muscle fiber, myofibril, myofilaments, sarcomere
It's possible that this is the cause of "knowing when someone is staring at you from behind". The eye muscle is the fastest reacting muscle of the whole body, contracting in less than 1/100th of a second.
leg is this correct
A whole muscle is the whole muscle while a muscle fiber is part of a muscle. I'm not sure if I'm correct though, so check with some different sources.
bodybuilding with the correct training and diet.
That is the correct spelling of "pectoral" (muscle of the upper chest).
Cardiac muscle tissue.
The correct order is: epimysium (outer connective tissue layer), perimysium (connective tissue surrounding muscle fascicles), endomysium (connective tissue surrounding individual muscle fibers), sarcolemma (muscle cell membrane), sarcoplasm (muscle cell cytoplasm), myofibrils (contractile units within muscle fibers).
latismus dorsi
An injury to either a muscle or the tissue that connects muscle to bone (called a tendon).
