Foetal finger joint, light micrograph

---

Light micrograph of a longitudinal section through a foetal finger joint. The finger bones are initially formed of cartilage (purple). Bone formation (ossification) starts from the middle of the cartilage and proceeds outwards. Areas where bone has already formed are red, areas of active ossification are dark purple. Either side of the bones are tendons and muscles. Magnification: x40 when printed at 15cm wide.
