Epiphyses

Definition

Epiphyses are the rounded ends of long bones, which contain spongy bone and red marrow. They are crucial for joint movement and growth during development.

5 Must Know Facts For Your Next Test

1. Epiphyses are found at the proximal and distal ends of long bones.
2. The epiphyseal plate, or growth plate, is located in the epiphysis and is where bone growth occurs in children and adolescents.
3. Once growth is complete, the epiphyseal plate ossifies and becomes an epiphyseal line.
4. Epiphyses are covered with articular cartilage to facilitate smooth joint movements.
5. The red marrow within the epiphyses is responsible for producing blood cells.
