perichondrium
Anatomical term for the dense connective tissue layer surrounding cartilage (except at articular surfaces).
The perichondrium plays an important role in cartilage growth and repair.
骨膜 (periosteum) is the analogous membrane covering bone, not cartilage.
Compound of 軟骨 (cartilage) + 膜 (membrane). The exact historical derivation is uncertain, but the term is a straightforward medical compound.
