The head of the humerus is almost hemispherical, while that of the femur forms about two-thirds of a sphere. Label the parts of a long bone. While their parts are similar in general, their structure has been adapted to differing functions. The metaphysis is the place where the diaphysis meets the epiphysis. Metaphysis. In this video we discuss the parts of a long bone and some of the functions of each of those bone parts. 4.1 proliferation zone The long bones of the arms are the radius and ulna. The largest part of any long bone is the long cylindrical middle, called the diaphysis. A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3.1). of 31. bone section spongy bone long bones epiphysis human femur compact bone anatomy structure of a bone bone marrow illustration long bone structure yellow bone marrow. This science quiz game will help you learn 15 of the most important bones. Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult. The diaphysis takes the brunt of the force a long bone must support, and is made up primarily of compact bone -- a dense, strong bone composed of minerals, including calcium, phosphorus and … anatomycorner.com/main/2015/07/08/label-the-parts-of-a-long-bone The adult femur is the largest bone in the body at about 2 feet long and is hollow to make it lighter. Gross Anatomy of Bones. Human skeleton - Human skeleton - Long bones of arms and legs: The humerus and the femur are corresponding bones of the arms and legs, respectively. For each item below, use the pull-down menu to select the letter that labels the correct part of the image. The structure of a long bone allows for the best visualization of all of the parts of a bone (Figure 1). 3,017 long bone anatomy stock photos, vectors, and illustrations are available royalty-free. Bones of the Skeleton - Science Quiz: The collection of bones in the human body is called the skeletal system. The shaft of a long bone, which is the direction at which the bone can withstand the most stress. The long bones in the legs are the femur, tibia, and fibula. This is where major bone growth occurs, as well as where blood enters the bone. The diaphysis is the hollow, tubular shaft that runs between the proximal and distal ends of the bone. Some, like the rib cage, provide protection for softer body parts, while other bones enable mobility by supporting the muscles. Periosteum.

Label the stages of long bone growth at the epiphyseal plate. It provides structure to the body, and each bone has a distinct purpose.
