Zoo teaching materials collection: "The structure and movement of animal bodies"

Let's use this exercise to consider the structure of Giraffe 's body by comparing it to that of a human. First, let's look at the structure of a Giraffe 's body.Foot bones and joint jointWe will investigate this, and then,gold meat meatFind a place where there are many of them.

Preparation: Print out a picture of Giraffe and an illustration of its bones.

1. Joints are the parts of the body that bend and straighten. While watching a video of Giraffe walking, find Giraffe 's joints and mark them on Giraffe 's photo, like the human photo on the right. You can mark as many joints as you like.

2. Humans and Giraffe look completely different in body shape, but in fact, the order in which their bones and joints are arranged is the same. For example, in a human leg, if you look from the center of the body, there is the "hip bone" followed by the "thigh bone (major ligament)," and then the "shin bone." The joint between the "hip bone" and the "thigh bone" is the "hip joint," the next joint is the "knee," and the joint after that is the "ankle."
Now, among the bones of Giraffe 's hind leg, which are the "thigh bone" and the "shin bone"? Also, where are the "hip joint," "knee," and "hind ankle" located? Write them on the illustration of Giraffe 's bones.

3. Compare the illustration of a Giraffe 's bones with a photograph of Giraffe, and draw the joints of the hind legs—"hip joint," "knee," and "hind ankle"—on Giraffe photograph as well. Also, watch a video of Giraffe walking again to confirm that the "hip joint," "knee," and "hind ankle" bend in those positions.

4. Like the illustration of the human body and the illustration of the bones below, the illustration of Giraffe bones and Giraffe body Outline outline If you compare them, you'll notice several places where the width differs significantly. Those are areas where there's a lot of muscle, Internal organs Internal organs It's a place where you might find things like that.
While looking at a picture of Giraffe or a video of Giraffe walking, try to find a place where the outline of the giraffe's body is wider than its bones. Once you find it, circle it on the illustration of Giraffe 's bones.

5. Let's also investigate Lion and African Bush Elephant using the same method. The photos, bone illustrations, and walking videos for each are...[Teaching material collection]It is located there.
