Chapter 48, Problem 14TYPSS

Summary Introduction

To review:

The reason behind force would differ if sarcomere were in a greatly stretched state at the beginning of the contraction versus in an average resting position.

Introduction:

The two types of filaments are thick and thin filaments and overlapping of these filaments form dark and light bands. A muscle fiber contains myofibrils which forms alternating light–dark units called sarcomeres. Sliding-filament theory proposed that thick filaments is composed of myosin, and thin filaments is composed of actin.
