Summary Introduction

To determine:

The labeling of skeletal muscle fiber.

The figure is labeled as shown below:

  Laboratory Manual for Holes Human Anatomy & Physiology Fetal Pig Version, Chapter 19, Problem F19.3A

1. Fascicle - Fascicle is a bundle of muscle fibers.

2. Sarcoplasmic reticulum - Sarcoplasmic reticulum is a membrane bound cell-organelle that is found in the muscle cells. Its function is to store calcium ions.

3. Tendon - Tendon is a fibrous connective tissue that joins muscles and bones. Its function is to make the bones movable.

4. Perimysium - Perimysium is sheet of connective tissue that surrounds the muscle fibers.

5. Nucleus − Nucleus is a membrane-bound organelle found in all eukaryotic cells. Muscle cells are multinucleated in nature.

Conclusion

The labeling of the figure is as follows:

1. Fascicle

2. Sarcoplasmic reticulum

3. Tendon

4. Perimysium

5. Nucleus
