Examples of metaphysis in the following topics:

  • Nerve and Blood Supply

    • After epiphyseal fusion in the growth of long bones, communication between the circulosus vasculosus and the end arteries of the metaphysis are established.
    • This minimizes the chances of osteomyelitis in the metaphysis.

  • Growth of Bone

    • The metaphysis is the wide portion of a long bone between the epiphysis and the narrow diaphysis.
    • After the zone of calcified matrix, there is the zone of ossification, which is actually part of the metaphysis .
    • Arteries from the metaphysis branch through the newly-formed trabeculae in this zone.
    • The bottom-most row is the zone of ossification which is part of the metaphysis.

  • Cartilaginous Joints: Synchodroses

    • The epiphyseal plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.

  • Development of Joints

    • Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate) .

  • Supply of Blood and Nerves to Bone

    • Blood supply of the immature bones is similar, but the epiphysis is a discrete vascular zone separated from the metaphysis by the growth plate.

  • Postnatal Bone Growth

    • Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate).
