Chimpanzee hand xray

Inside of the hard, protective hoof material is a single, large “finger.” Despite being covered by the hoofy material, separations between the phalanges can still be seen. The zebra has a hoof similar to that of a horse. This x-ray is of poor quality because it is difficult to x-ray a whale. The whale’s flipper is curved and acts to push its heavy body through the water. It is no surprise, then, that its bones are so massive. The beluga whale is the largest animal xrayed in this activity. This bear was x-rayed because it has a deformity. They have long claws at the tip of their phalanges. They use their front paws for walking and digging. Their small size is evident by the thin bones in their front paws. Malaysian sun bears are smaller than most bears. Their shape provides a good support for the paddle-shaped flipper. The phalanges are long, thin, and slightly curved.

Like the macaque monkey, this x-ray is also of a juvenile.

This California sea lion uses its hand for pushing water as it swims. The cartilage in the area of bone growth is not visible on an xray, so the ends of the bones look like they are not connected.Ġ5 sea lion flipper Epiphyseal (growth) plates The monkey shown here is a juvenile whose bones are still growing. Short, nonopposable thumb Epiphyseal (growth) plates Lumpy flesh padding phalangesĠ4 macaque monkey hand This small monkey uses its hands to swing through trees and to manipulate objects. Limited classroom reproduction rights are granted under the notice appearing earlier in this work. The tips appear dense on the xray where they curve downward. The only joint in the phalanges is very large and is used more as a shock absorber than as a flexible joint.

This lion paw has thick bones to support the massive weight of the animal as it walks. The hyena’s four phalanges (skeletal fingers) are designed to support weight, and the thick pads protect the paw from sharp objects on the ground. Note the claws at the tip of the “fingers” and the padding underneath. This hyena paw is similar to a dog or cat paw. Goal Students will explore the relationship between structure and function and compare homologous structures across species.Įvolution Animals Homologous structures Comparative anatomy Functional morphologyįorm & Function Modeling & Visualization Diversity & Evolution Behavior This hand belongs to a feSeveral joints in fingers to facilitate male. The fingers to fingers are slender and designed for performing precise tasks. Examine the digital images as well because many of the features do not show up clearly on paper.Ġ1 human hand Note the long, opposable thumb and the Long thumb relative number of joints in the fingers. Each of these images has interesting features that can be discussed or explored. For example, although five separate “fingers” can be seen in the sea lion x-ray, these bones actually make up a single flipper. X-ray images can be deceiving, and students should be aware that the hands will look different in x-ray than in regular photographs. Encourage students to relate structure to function first, and then function to animal lifestyle, rather than merely matching x-ray to animal. The lesson is designed so that students describe the features of the x-ray images and then attribute possible functions to the various forms. Thus, Animal Hands is an excellent activity for students learning image processing. Students can share discoveries with one another and give advice on useful image processing techniques. The problem solving focus of the activity encourages cooperative learning and exploration. By manipulating the images in different ways, students bring out previously hidden features of the hands. The image processing in this activity is open-ended, and the student text contains simple instructions for several possible image processing techniques. The hands chosen for this activity have a variety of different functions including swimming, walking, flying, and grabbing. Students enhance and examine 10 x-ray images of animal hands. In this lesson, students use x-rays of different animal hands to examine the relationship between structure and function. Different functions of homologous structures Background
