What This Document Is
This document contains detailed laboratory instructions for Week One of BIOS 256, Anatomy & Physiology IV With Lab at Chamberlain University. It outlines a series of hands-on activities centered around the dissection of a fetal pig, designed to provide a practical understanding of mammalian anatomy, specifically focusing on the digestive system and thoracic cavity. The lab work is blended, meaning it combines in-person dissection with guided instructions.
Why This Document Matters
This lab manual is essential for students enrolled in BIOS 256. It serves as a direct guide during the first week’s laboratory session, providing the necessary steps to successfully complete the fetal pig dissection. Understanding the anatomical structures through dissection reinforces theoretical knowledge gained in lectures and prepares students for more complex physiological concepts. This lab is foundational for subsequent studies of organ systems and their functions.
Common Limitations or Challenges
This document provides *instructions* for dissection, but it does not *replace* the need for careful observation, critical thinking, and instructor guidance. It assumes a basic understanding of anatomical terminology. While figures are included, they are visual aids and do not provide exhaustive detail. This preview does not include the full set of figures referenced within the document.
What This Document Provides
The full document includes:
* Detailed, step-by-step instructions for external and internal pig dissection.
* Guidance on measuring and estimating the age of the fetal pig.
* Specific instructions for opening the thoracic and abdominal cavities.
* Detailed directions for identifying key organs within the digestive system (liver, stomach, esophagus) and thoracic cavity (heart, lungs, trachea, thymus, thyroid).
* Figures illustrating external anatomy, thoracic cavity anatomy, and incision lines for dissection.
* Instructions for examining specific anatomical features like the umbilical cord, peritoneum, and portal vein.
This preview *does not* include the complete set of figures, the full age estimation chart, or the detailed anatomical descriptions found within the complete lab instructions. It also does not include any post-dissection analysis questions or assessment materials.
