Sense: adjective/1
The adjective 'distal' is primarily an anatomical term, contrasting directly with its opposite 'proximal'. While 'distal' always describes a position farther from a specific reference point (the body's centre or an attachment site), 'peripheral' is broader — it refers to outer or boundary areas without implying measurable distance from a fixed origin. 'Terminal' is narrower: it means at the very end or tip, so a distal phalanx is also terminal, but a distal forearm is not. The key distinction is that 'distal' is relative (farther than something else), 'terminal' is absolute (the endpoint itself), and 'proximal' is the inverse (closer to the reference point). A doctor might say 'the fracture is in the distal third of the humerus' (farther from the shoulder than the rest) but would describe a fingertip injury as involving the 'terminal phalanx' (the last bone).

Etymology
Borrowed into English in the early 19th century from the Latin root 'distare', meaning 'to stand apart' (from 'dis-', apart, and 'stare', to stand). It was formed as an anatomical term paired with 'proximal' to give doctors a precise way to describe positions along a limb or structure relative to a central reference point.
