Did you know that the diaphysis is the main part of a long bone?

Really? I always thought it was just the entire bone itself.

Nope, it's specifically the shaft, which is pretty interesting.

That makes sense! Anatomy can be so detailed sometimes.

Root Explanation

Diaphysis → It is formed from "dia-" (meaning through or across) and "physis" (from Greek "phusis", meaning growth or nature). The term refers to the main or central part of a long bone, which is the section that grows through the length of the bone.

Memory Tip

Think of 'growing through' — 'dia-' means through, and 'physis' relates to growth. This helps you remember that diaphysis refers to the central part of a bone that grows.
