Question
Chapter 10, Problem 27CP
Summary Introduction
To determine:
The reason that the smooth muscles contract over a wider range of resting lengths than skeletal muscles
Introduction:
Smooth muscles have short and spindle shaped cells, and the actin and myosin filaments are spread all over the cells. The Ca2+ requirement of the cells is fulfilled either by extracellular uptake or from intracellular storage. These muscles are found in the respiratory and digestive tract of the body and are involved in the peristaltic movement, and the reproductive secretions.
