Fetal Pig Dissection Lab Overview: Fetal Pig Dissection Lab Worksheet
The fetal pig dissection lab provides students with an opportunity to study the anatomy of a mammal in detail. Through dissection, students can observe the various organs and structures of the fetal pig and gain a better understanding of their function and interrelationships.
The lab also emphasizes the importance of proper dissection techniques and safety protocols to ensure a successful and educational experience.
Objectives
- To identify the external and internal anatomy of the fetal pig.
- To understand the function of major organs and systems.
- To develop proper dissection techniques and safety protocols.
- To prepare a comprehensive dissection report.
External Anatomy of the Fetal Pig, Fetal pig dissection lab worksheet
The external anatomy of the fetal pig can be divided into several regions: the head, neck, trunk, and limbs. The head region includes the eyes, ears, nose, and mouth. The neck region is relatively short and connects the head to the trunk.
The trunk region contains the chest and abdominal cavities, which house the major organs. The limbs include the forelimbs (arms) and hindlimbs (legs).
| Feature | Male | Female | Description |
|---|---|---|---|
| Genitalia | Scrotum | Vulva | External reproductive organs |
| Umbilical Cord | Present | Present | Connects the fetus to the placenta |
| Eyes | Open | Open | Eyelids are not fully developed |
| Ears | External ears present | External ears present | Ears are not fully developed |
Internal Anatomy of the Fetal Pig
The internal anatomy of the fetal pig includes the major organs and systems of the body. The heart is located in the chest cavity and is responsible for pumping blood throughout the body. The lungs are also located in the chest cavity and are responsible for gas exchange.
The liver is located in the abdominal cavity and is responsible for detoxifying the blood and producing bile. The digestive system includes the stomach, small intestine, and large intestine, which are responsible for digesting and absorbing nutrients from food.
Dissection Procedures
The dissection of the fetal pig should be performed carefully and methodically. The following steps provide a general overview of the dissection procedure:
- External Examination: Examine the external features of the fetal pig and identify the major regions and organs.
- Incisions: Make incisions along the ventral surface of the fetal pig to open the chest and abdominal cavities.
- Organ Removal: Remove the major organs from the chest and abdominal cavities and examine their structure and function.
- Tissue Examination: Examine the tissues of the fetal pig under a microscope to observe the cellular structure.
Materials and Equipment
- Fetal pig specimen
- Dissecting tray
- Dissecting tools (scalpel, scissors, forceps)
- Microscope
- Slides and coverslips
Fetal Pig Dissection Report
The fetal pig dissection report should include the following components:
- Observations: Describe the external and internal anatomy of the fetal pig, including the major organs and their functions.
- Conclusions: Summarize the key findings of the dissection and discuss the implications of these findings.
- Discussion: Discuss the relevance of the fetal pig dissection to the study of human anatomy and physiology.
