epiphysis

 [e-pif´ĭ-sis] (pl. epi´physes) (Gr.)
1. the end of a long bone, usually wider than the shaft, and either entirely cartilaginous or separated from the shaft by a cartilaginous disk.
2. part of a bone formed from a secondary center of ossification, commonly found at the ends of long bones, on the margins of flat bones, and at tubercles and processes; during the period of longitudinal growth, epiphyses are separated from the main portion of the bone by cartilage. adj., adj epiphys´eal.

(e-pif'i-sis, -sēz), [TA]
A part of a long bone developed from a secondary center of ossification, distinct from that of the shaft, and separated at first from the latter by a layer of cartilage.
[G. an excrescence, fr. epi, upon, + physis, growth]

epiphysis

(ĭ-pĭf′ĭ-sĭs)
n. pl. epiphy·ses (-sēz′)
1. The end of a long bone that is originally separated from the main bone by a layer of cartilage but later becomes united to the main bone through ossification.

epiphysis

The growing sector at the end of a long bone. During the period of growth, the epiphysis is separated by a plate of CARTILAGE from the shaft of the bone. The edge of this plate nearest the shaft becomes progressively converted into bone, while the other edge develops new cartilage. In this way, the bone lengthens.

epiphysis

the ossified part of the end of a mammalian limb bone or vertebra which, during growth, is separated by a plate of cartilage from the rest of the ossified bone. When growth is complete the epiphysis fuses with the rest of the bone. Compare DIAPHYSIS.
