Lab 7 appendicularial skeleton

Introduction

Similar to lab 6, lab 7 will be divided into 2 parts. The first part we will look at the pectoral girdle, the arms and the hands. For the second part we will look at the hips, legs, and feet. Normally this is done as 1 lab but I really want you to spend time on the landmarks of each bone. We will start by trying to assemble the arms. This is an activity you would normally have done with lab 5 but I felt it fit better here. We will then look at the both rotating models and mouse over models for the pectoral girdle, humerus, lower arm (ulna and radius) and hand.

The arms

For this activity, I want you to just learn what the bones of the arm are and their correct positioning. Normally I have students build a skeleton for me out of disarticulated bones and then I go through with them the names of the bone and the proper orientation.
  • Watch the video on the arms.
  • Click the anterior view. Try to assemble the right and left arm correctly.
  • Take a screen shot (and you will have to give me an expliantion)
  • To to the the posterior view. Try to assemble the right and left arm correctly.
  • Take a screen shot (and you will have to give me an expliantion)

Landmarks of the limbs

We will look at each bone below. I set up the lab to take you to these pages too. I am not sure if which is easier. For each part, you will look at the watch my video and find the structures on the rotating model. Then you will find the structures on the mouse over model.

The Pectoral Girdle

Clavical and scapula

  • We will now look at the clavical and the scapula.
  • First go to the 360 model.
  • For the clavcle, try to differentate between the sternal end and the acromial end.
  • For the sternum, find all the bold landmarks.
  • Next go to the mouse over models.
  • Identify the landmarks.
