뼈를 둘러싸고 있는 막(골막 periosteum)은 두층으로 구성 outer "fibrous layer" and inner "osteogenic layer"

[문형철]

골막은 두개의 층으로 구성

골막은 dense irregular connective tissue 임.  periosteum has nociceptive nerve endings임. 

골막의 2층 ; outer "fibrous layer" and inner "osteogenic(cambium) layer"

The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts.

Periosteum is a membrane that lines the outer surface of all bones,^[1] except at the joints of long bones.^{[nb 1]} Endosteum lines the inner surface of all bones.

Periosteum consists of dense irregular connective tissue. Periosteum is divided into an outer "fibrous layer" and inner "cambium layer" (or "osteogenic layer"). The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts. These osteoblasts are responsible for increasing the width of a long bone^{[nb 2]} and the overall size of the other bone types. After a bone fracture the progenitor cells develop into osteoblasts and chondroblasts, which are essential to the healing process.

- 골막은 dense 불규칙한 결합조직. 

- 골막은 두개의 층으로 나뉘는데, 바깥쪽은 fibrous layer이고, 안쪽은 cambium layer임. 

- 섬유층막은 섬유아세포를 포함하고, 형성층 막은 progenitor 세포를 포함함. 

- 이러한 osteoblast는 긴뼈의 넓이를 증가시키고, 다른 뼈의 전체적인 크기를 늘림. 

- 골절후 progenitor 세포는 osteoblast와 chodroblast로 발전하여 치유반응을 촉진함. 

As opposed to osseous tissue, periosteum has nociceptive nerve endings, making it very sensitive to manipulation. It also provides nourishment by providing the blood supply. Periosteum is attached to bone by strong collagenous fibers called Sharpey's fibres, which extend to the outer circumferential and interstitial lamellae. It also provides an attachment for muscles and tendons.

- 뼈조직과 반대로, 골막은 통증수용기를 가지고 있음. 골막은 혈액공급이 풍부함.

- 골막은 강한 콜라겐 파이버가 부착하는 샤피섬유라 불리는 부위가 있음. 이는 뼈와 근육을 연결하는 부위임. 

참고) 샤피 섬유 sharpey's fiber(bone fiber)

Sharpey's fibers (bone fibers, or perforating fibres) are a matrix of connective tissue consisting of bundles of strong collagenous fibres connecting periosteum to bone. They are part of the outer fibrous layer of periosteum, entering into the outer circumferential and interstitial lamellae of bone tissue. Sharpey's fibres are also used to attach muscle to the periosteum of bone by merging with the fibrous periosteum and underlying bone as well. A good example is the attachment of the rotator cuff muscles to the blade of the scapula.
