[3] [4] Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate). During formation of the secondary ossification center, vascular canals (epiphysial canals) stemming from the perichondrium invade the epiphysis, supplying nutrients to the developing secondary ...
The metaphysis (pl.: metaphyses) is the neck portion of a long bone between the epiphysis and the diaphysis. [1] It contains the growth plate , the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses.
dia-+ physis, "between the growth parts" epiphysis: The end regions of a long bone; regions of secondary ossification. epi-+ physis, "on top of the growth part" physis (epiphyseal plate) Also known as the growth plate. In a long bone it is a thin disc of hyaline cartilage that is positioned transversely between the epiphysis and metaphysis. In ...
The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
At the end of the formation of the secondary ossification center, the only two areas where the cartilage remains is at the articular cartilage covering the epiphysis and at the epiphyseal plate between the epiphysis and diaphysis. [3] A schematic for long bone endochondral ossification: [4]
An epiphyseal line is an epiphyseal plate that has become ossified. [1] The process of it forming from an epiphyseal plate is named epiphyseal closure . [ 2 ] In adult humans, it marks the point of fusion between the epiphysis and the metaphysis .
The left side of your body houses your heart, ribs, stomach, and more, and pain under left breast can be caused by issues related to any of these organs.
The diaphysis and both epiphyses of a long bone are separated by a growing zone of cartilage (the epiphyseal plate). At skeletal maturity (18 to 25 years of age), all of the cartilage is replaced by bone, fusing the diaphysis and both epiphyses together (epiphyseal closure). [ 45 ]
