An X ray demonstrating the characteristic finding of lead poisoning in humans—dense metaphyseal lines. Because of their rich blood supply and vascular stasis, metaphyses of long bones are prone to hematogenous spread of osteomyelitis in children. [4]
The lines are believed to trace the migration of embryonic cells. [4] They do not correspond to nervous, muscular, or lymphatic systems. The lines are not unique to humans and can be observed in other non-human animals with mosaicism. [9] [10] Alfred Blaschko is credited with the first demonstration of these lines in 1901. [11]
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).
Pseudoachondroplasia. Leg radiographs depicting dysplastic distal femoral and proximal tibial epiphyses, and distal femoral metaphyseal broadening, cupping, irregularities (white arrows) and radiolucent areas especially medially. Note the metaphyseal line of ossification of the proximal tibias (blackarrows) and relative sparing of the tibial ...
Knees have metaphyseal widening and irregularity while hands have brachydactyly (short fingers) and proximal metacarpal rounding. Flat feet are very common. [2] The spine is normal but may have a few irregularities, such as scoliosis. [citation needed]
What they look like: Chiggers, a type of small mite, typically leave clusters of bites that are often very itchy. In many cases, chigger bites appear as small, red and itchy bumps. Sometimes, they ...
