Microscopic Anatomy and Physiology

of Muscle

Skeletal Muscle Learning Objectives
Structure
Excitation, Contraction, and Relaxation • Define and be able to explain the signifi-
Strength of Contraction cance of the bold italic terms in this
chapter.
Drugs That Affect Skeletal Muscle Function • Compare and contrast the microscopic
Types of Muscle Contraction structure and location of skeletal, smooth,
Smooth Muscle and cardiac muscles.
Structure • Compare and contrast excitation and
Stress–Relaxation contraction of skeletal, smooth, and
cardiac muscles.
Contraction and Relaxation • Compare and contrast autonomic nervous
Role and Sources of Calcium system innervation of skeletal, smooth,
Action Potentials and Slow Waves and cardiac muscles. Describe the critical
Autonomic Innervation role that calcium plays in smooth and
Cardiac Muscle skeletal muscle.
Excitation and Contraction • How is ATP replenished in the cell and
Cardiac Hypertrophy what is its role in muscle?
• Briefly describe the generation of an
action potential in smooth muscle.
