Activity system

Features of the human activity system: Left image: α = Serratus magnus, β = Deltoid, γ = Biceps, δ = Poupart's ligament, ε = Patella, T.P. = Tranpyloric plane, S.C. = Subcostal plane, I.T. = Intertubercular plane. Right image: β = Dimple over posterior superior spine of ilium, γ = Lower angle of scapula, δ = External head of triceps, ε = Depression over great trochanter ζ = Popliteal space, η = Gastrocnemius. (The scale between the figures represents head-lengths.)

The Activity system is the part of human anatomy responsible for movement with muscles and the human skeleton (structural support and protection with bones, cartilage, ligaments, and tendons).

The term activity system is also used as a short-hand for human activity system. This is a term used within Peter Checkland's Soft Systems Methodology to refer to a logical collection of activities designed to fulfill some purpose.
