Presentation Transcript

  1. Anatomical Direction Fetal Pig Dissection

  2. Dorsal Cranial Caudal Ventral

  3. Anterior Posterior

  4. Medial: Closer to the trunk Lateral: Further from the trunk

  5. Proximal: Closer to a reference point For example: The elbow is proximal to the shoulder, while the wrist is more distal to the shoulder. Distal: Farther from a reference point

  6. Basic Appearance

  7. Internal Anatomy

  8. Classification Artiodactyla Suidae Sus Sus scrofa sapiens

  9. Think about these comparisons:

  10. Respecting your specimen. What lab safety rules must we follow in order to protect ourselves, our classmates, and to respect the life of the fetal pig during the dissection lab?

  11. Determining Age of your Pig

  12. Determining the Sex of your Pig

  13. Preparing to Dissect

  14. What are the tools we will use?

  15. Decide on ventral-incision style based upon the gender of your fetal pig Making the Incisions:

  16. Dissection tip: Start above the umbilical cord Always cut pulling upward Making the Incisions:

  17. Which systems will we explore through dissection? • Digestive System – Day One • Respiratory System – Day Two • Circulatory System – Day Two • Excretory System – Day Three • Reproductive System – Day Three Each day, before we begin, we will explore a virtual dissection online: http://www.whitman.edu/biology/vpd/main.html
