Physis (/ ˈ f aɪ ˈ s ɪ s /; Ancient Greek: φύσις; pl. physeis, φύσεις) is a Greek philosophical, theological, and scientific term, usually translated into English—according to its Latin translation "natura"—as "nature".
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 ...
There are four types of epiphyses: Pressure epiphysis: The region of the long bone that forms the joint is a pressure epiphysis (e.g. the head of the femur, part of the hip joint complex).
In running and jumping movements, extreme contraction of the knee extensors can result in avulsion fractures of the tuberosity apophysis. [3] A cast is all that is required if the fragment is not displaced from its normal position on the tibia. However, if the fracture fragment is displaced, then surgery is necessary to allow for normal ...
In the skeleton of humans and other animals, a tubercle, tuberosity or apophysis is a protrusion or eminence that serves as an attachment for skeletal muscles. The muscles attach by tendons , where the enthesis is the connective tissue between the tendon and bone . [ 1 ]
Fracture of the cartilage of the physis (growth plate) II – A = Above. The fracture lies above the physis, or Away from the joint. III – L = Lower. The fracture is below the physis in the epiphysis. IV – TE = Through Everything. The fracture is through the metaphysis, physis, and epiphysis. V – R = Rammed (crushed). The physis has been ...
The "apophysis", which is the secondary ossification center of the bone, and is normally present at 10 – 16 years of age. [ 8 ] Os vesalianum , an accessory bone which is present in between 0.1 - 1% of the population.
