The tibia, located medially, bears most of the body's weight, while the fibula, positioned laterally, is smaller and supports leg structure. Further down the leg are the metatarsal bones, found near the distal end of the hindlimb. These bones are positioned proximal to the toe bones, or phalanges, providing support and structure in the foot.
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).
However, it serves as an indicator of the boundary between the epiphysis and diaphysis. [4] References This page was last edited on 30 July 2024, at ...
In a disorder known as rachitis fetalis anularis the ends of the long bones (epiphyses) are enlarged. [2] Another disorder, rachitis fetalis micromelica, is a deficiency in the growth (as a shortness) of the bones. [2] There is a surgical procedure called distraction osteogenesis which is used to lengthen long bones. [3]
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
The axillary nerve is located at the proximal end, against the shoulder girdle. Dislocation of the humerus's glenohumeral joint has the potential to injure the axillary nerve or the axillary artery. Signs and symptoms of this dislocation include a loss of the normal shoulder contour and a palpable depression under the acromion.
Contact dermatitis. What it looks like: Contact dermatitis has the same symptoms mentioned above, and can be a red rash that appears scaly or blistered, depending on its cause and severity.This ...
Greater trochanter is labeled at right. The greater trochanter of the femur is a large, irregular, quadrilateral eminence and a part of the skeletal system. It is directed lateral and medially and slightly posterior. In the adult it is about 2–4 cm lower than the femoral head. [1]
