The names of skeletal views, subsystems, bones and joints represent some important labels on a complete diagram of the skeletal system. The names of the type and parts of a bone, and its internal anatomy, are significant on call outs and exploded views of one or more individual bones.
View labels give perspective on the diagram of a skeletal system as a whole, allowing interpretation of the information provided. Most diagrams display either the front, back or side view of a skeleton, and the associated labels are anterior, posterior or lateral. Another diagram view label indicates whether the skeleton represents a male or female body.
The axial and appendicular skeletons are the two subsystems that make up a complete skeletal system. The axial skeleton includes the structures along the body's central line, including the skull, rib cage and vertebra. The appendicular skeleton supports movement and includes the upper and lower limbs, and the pectoral and pelvic girdles. Typically, different colors and labels distinguish the skeletal subsystems on a diagram.
Labels showing bone names are the most prevalent labeling category. Bone labels are often blank, allowing students to fill in the appropriate names. Typically, only major bones receive labels on static diagrams. With 206 bones in the human skeletal system, space precludes labeling every bone, unless the diagram is interactive. Joint labels are less common than bone labels, and they represent the point where unfused bone structures interact.
