Chapter 29, Problem 10WIO

Summary Introduction

To explain:

The process how the muscles lengthen when you stretch.

Concept Introduction:

Muscles are composed of the thick band of myosin and thin band of actin. There are other proteins involved in the movement of the muscles like troponin, and tropomyosin. These muscles respond to the stimulus of contraction and relaxation by the transmission of the signal waves of impulse across the neuromuscular junctions at the nerve endings. The action potential is generated and moves ahead in the neurons.
