Activity 1: Examining the Gross Anatomy of Bones
1. Contrast (find 2 differences) between the epiphyseal plate and the epiphyseal line.
2. Describe the medullary cavity and include its location, the substance found in this cavity and the function of the substance.
Activity 2: Examining the Cartilage Associated with BonesÂ
3. For each of the following, indicate whether you would find hyaline cartilage (H) or fibrocartilage (F) at this location.
-
- __________ pubic symphysis
- __________ articulating surfaces
- __________ growth plate
- __________ intervertebral disks
- __________ costal cartilage
- __________ meniscus
4. Identify the three types of cartilage and label the three cartilage images using the following terms: collagen fibers, elastic fibers, ground substance, and chondrocytes.
5. Describe the features of hyaline and fibrocartilage by filling in the chart below.
| Hyaline Cartilage | Fibrocartilage | |
| Amount of ground substance |
||
| Amount of fibers |
||
| Function |
Activity 3: Examining the Microscopic Histology of Bones
6. Describe the basic structural similarities and differences between spongy bone and compact bone. Use the histology images below to help you answer this question.
Activity 4: Examining the Components of Bone
7. Briefly describe the effect of heat on bone matrix.
8. Briefly describe the effect of acid on bone matrix.
