8. Muscular Tissues

Specific Objectives:

At the end of this lecture, the student will be able to:

  1. Describe the basic structural and functional characteristics that distinguish muscular tissues from the other tissue types.
  2. Compare and contrast the 3 major types of muscle tissues.
  3. Describe the relationship between skeletal muscle fascicles, fibers, myofibrils, and myofilaments.
  4. Describe the molecular composition of the sarcomere.
  5. Describe the process of skeletal muscle stimulation and contraction.

Lectures:

Part 1

This lecture examines the general characteristics of skeletal muscle.

Part 2

This lecture examines the basic contractile physiology of muscular tissues.

Part 3

This lecture examines the general characteristics of cardiac and smooth muscle cells.

Laboratory:

This video provides an overview of the important concepts to remember as studying histological images to learn about muscular tissues.
