Summary Introduction
Introduction:
Myofibrils are the key to muscle contraction and they are the long protein cords that fill most of the muscle cells. Each myofibril is a bundle of parallel protein micro filaments called myofilaments .There are three kinds of myofilaments are thick, thin, and elastic filaments.

Thick myofilaments consist mainly of the protein _____.
hypoventilation builds up carbon dioxide in the body which causes respiratory acidosis. This would break down thick and thin myofilaments. Why exactly would that happen?
Calcium is released from the sarcoplasmic reticulum following death. Without available ATP, rigor mortis (stiffening of the body) occurs. Explain why, if ATP is unavailable, muscles remain in a contracted state
