the.com/skeletal system

means The internal framework of bones, cartilage, and joints that supports the body, protects organs, and anchors muscles so you can stand, move, and not collapse into a puddle.

from 'Skeletal' traces to Greek 'skeletos,' meaning 'dried up' or 'desiccated' — from 'skellein,' to dry out — because a skeleton is literally what's left once the flesh has withered away. 'System,' from Greek 'systema' (a whole compounded of parts, from 'synistanai,' to combine), got bolted on later once anatomists realized bones weren't just leftover scaffolding but an organized, interconnected structure doing coordinated work.
