The Human Body’s Jobs
• Reproduction• Defense barrier
– Skin & microbes– Bone, muscle and soft organs
• Input/output– Oxygen & fuel consumption, hydration– Waste elimination
![Page 11: Anatomy Concepts Jeff Ericksen, MD Assistant Professor, Physical Medicine & Rehabilitation](https://reader034.vdocuments.us/reader034/viewer/2022051018/56649ccc5503460f94995881/html5/thumbnails/11.jpg)
The Human Body’s Jobs
• Movement & biomechanics– Muscles, connective
tissues, skeleton, skin
• Art form?

• Planes of reference
• Positional relationships
• Movement definitions– Joint movements, limb movements, whole body
movements

Structural Concepts
• Biologic design consists of balance between tension and compression structural elements in viruses, cells, organs and whole animals.– Tensegrity = tension integrity– Buckminster Fuller & geodesic domes.
![Page 38: Anatomy Concepts Jeff Ericksen, MD Assistant Professor, Physical Medicine & Rehabilitation](https://reader034.vdocuments.us/reader034/viewer/2022051018/56649ccc5503460f94995881/html5/thumbnails/38.jpg)
Musculoskeletal System
• Tensile elements = muscles, ligaments, tendons, joint capsules, menisci, and fascia.
• Compression elements = bones.

Tensegrity Allows Torque Reduction
