Identify microscopically:

1. Muscle fibers

2. Nuclei of the heart muscle fibers

3. Intercalary discs and cross striations

4. Connective tissue

Draw and annotate:

A few heart muscle fibers. Indicate the different components in detail.

1. Which bands are visible with the light microscope?
2. How do the intercalary discs appear?
3. What are the regions at the poles of the nucleus called and how are they formed?
