Skeletal System Diagram

Skeletal system diagrams are illustrations of the human skeleton, used mostly for educational purposes or in presentations. Skeletal diagrams are tools used by students to learn and study all 206 bones (this number can vary from person to person) of the human body. There are four main categories of bones: long, short, irregular, and flat. Some skeletal diagrams show smaller sections of the human skeleton. These are usually a grouping, such as bones of the head, spine, feet and hands.

Types of Skeletal System Diagrams

There are many different types of skeletal diagrams. These include complete skeletal diagrams of the anterior, posterior or lateral view, or more detailed views of specific groupings of bones such as the pelvis, head, rib cage or spine. Specialized skeletal diagrams show skeletons of fetuses, children, males, or females.

Anterior View Skeletal Diagram: This is an anterior view skeletal diagram showing the frontal view of the human skeleton.

Posterior View Skeletal Diagram: A posterior view skeletal diagram provides a back view of the human skeleton.

Lateral View Skeletal Diagram: A lateral view skeletal diagram offers a side view of the human skeleton.

Lateral View Skeletal Diagram

Skeletal diagrams can also be used to show bone development or growth which begins en utero. Bone growth diagrams show the progression of development of the bone over a period of time. This visually displays where a bone accepts blood vessels or where cartilage develops. This type of skeletal diagram also may show a cross section of a bone and the different layers within a bone: bone marrow, osteoclasts, cancellous bone, and cortical bone.

Skeletal system diagrams are often used in a classroom environment, both as a part of lesson plans and as quiz material. They are also often used for display purposes in doctors' offices or as part of a presentation.
