Anatomical Direction

Dorsal

VentralCranial Caudal

Anterior Posterior

Medial: Closer to the trunk

Lateral: Further from the trunk

Proximal: Closer to a reference point

Distal: Farther from a reference point

For example: The elbow is proximal to the shoulder, while the wrist is more distal to the shoulder.

Think about these comparisons:

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?

Determining Age of your Pig

Determining the Sex of your Pig

Preparing to Dissect

What are the tools we will use?

Making the Incisions:

Decide on ventral-incision style based upon the gender of your fetal pig

Making the Incisions:

Dissection tip:• Start above the umbilical cord• Always cut pulling upward

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
