Chapter 9.8, Problem 66AYP
Summary Introduction
To analyze:
The functional properties of smooth muscle which are different from skeletal muscle.
Introduction:
Smooth muscles are muscles that possess a single nucleus and are spindle-shaped with no striations. Smooth muscle is involved in performing functions like movement of food in the digestive tract, regulating the diameter of blood vessels and in contracting the gland duct. Skeletal muscle is striated in appearance and possesses multiple nuclei that lie at the periphery position. They help in body movement.

Skeletal muscle has several distinct fiber types. Type I is used primarily for aerobic activity, whereas type II b is specialized for short, intense bursts of activity. How could you distinguish between these types of muscle fiber if you viewed them with an electron microscope?
