diaphyses

Examples of diaphyses in the following topics:

• Cartilaginous Joints: Synchodroses

  • Such joints are found between the epiphyses and diaphyses of long bones, between the occipital and the sphenoid bones, and during the early years of life, between the petrous portion of the temporal and the jugular process of the occipital bone.

• Growth of Bone

  • On the diaphyseal side, cartilage is ossified, allowing the diaphysis to grow in length.
  • The more mature cells are situated closer to the diaphyseal end of the plate.

• Development of Joints

  • For instance, if a skeleton is found and the epiphyses are missing or unfused to the diaphyses, then the examiner knows that the skeleton is that of a juvenile or young adult: if female, probably under age 18; if male, probably under age 25.

• Metatarsal Fracture

  • The diaphyseal bone, where the fracture occurs, is an area of poor blood supply.

• Stages of Bone Development

  • They are responsible for the formation of the diaphyses of long bones, short bones, and certain parts of irregular bones.

• Supply of Blood and Nerves to Bone

  • One or two main diaphyseal nutrient arteries enter the shaft obliquely through one or two nutrient foramina leading to nutrient canals.
