Systems in Action

The human skeletal system is composed of the appendicular and axial skeletons, each with distinct subsystems that perform crucial functions. The appendicular skeleton includes the pelvic girdle, leg bones, arm bones, and shoulder girdle, which support body weight, enable movement, and withstand stress during activities.

Systems in Action

severe trauma to any of these subsystems are categorized as "side effects" since they result in undesirable outcomes

Examining Physical Systems

human skeletal system
components

axial skeleton

skull

to protect brain and support facial structure

severe trauma to this subsystem can cause a skull fracture

vertebrae

vertebrae can develop osteoporosis because of malnutrition and other reasons

(osteoporosis is a skeletal disease that weakens the vertebrae)

protects spinal cord and supports and allows movement to body

ribcage

trauma to the chest can cause ribs to break, which in turn causes sharp pains to inner organs

shields heart and lungs while providing structural stability to upper body

appendicular skeleton

subsystems

leg bones

to allow us to perform crucial functions such as moving, standing and performing other various activities

pelvic girdle

to support body weight and hold leg bones in place

shoulder girdle

allows the shoulder a large range of motion, and acts as an anchor to

arm bone

help arms withstand stress during exercise and other various activities
