plural per·i·chon·dri·a [per-i-kon-dree-uh]. /ˌpɛr ɪˈkɒn dri ə/. Anatomy.
- : the membrane of fibrous connective tissue covering the surface of cartilages except at the joints.

Perichondrium, per-i-kon′dri-um, n. the fibrous investment of cartilage.
In the earliest stage the future bone consists of hyaline cartilage surrounded by a vascular sheath, the perichondrium.
At the same time beneath the perichondrium osteoblasts are developed which also begin to give rise to spongy bone.
The perichondrium thus becomes the periosteum, and the bone produced by it, is periosteal or membrane bone.
The reflected flaps of muco-perichondrium are replaced and maintained in position for 48 hours with plugs of cotton-wool.
