Activity Description

The objective for this lab is to allow students to observe and compare the microscopic structure of compact and spongy bone. The bone specimens from activity 4B Determination of Bone Density may be used for this activity. Students will use a hand lens or dissecting microscope to observe and draw a bone specimen cut from the end of the long bone and from the mid section. They will answer questions to compare the location of types of bone and their densities calculated from activity 4B. The spongy (cancellous or trabecular) bone at the ends of the long bone specimens should have the least density, while the specimens from the mid-section of the compact (or solid) bone located along the shaft should have a greater density.
