A long bone can be divided into two parts – (1) the central shaft or diaphysis and (2) the epiphyses (singular: epiphysis), the bulky ends on both sides. There is a narrow section called (3) metaphysis between the diaphysis and epiphysis.
The flat bones of the face, most of the cranial bones, and a good deal of the clavicles (collarbones) are formed via intramembranous ossification, while bones at the base of the skull and the long bones form via endochondral ossification.

Bone formation, process by which new bone is produced. Ossification begins about the third month of fetal life in humans and is completed by late adolescence. The process takes two general forms, one for compact bone and the other for cancellous bone. Learn about the process of bone formation.

Jul 27, 2024 · A long bone is a type of bone characterized by its elongated shape and is typically longer than it is wide. These bones are primarily composed of a central shaft, known as the diaphysis, and two expanded ends called the epiphyses.
The epiphyseal plate is the area of growth in a long bone. It is a layer of hyaline cartilage where ossification occurs in immature bones. On the epiphyseal side of the epiphyseal plate, cartilage is formed. On the diaphyseal side, cartilage is ossified, and the diaphysis grows in length.
Anatomy of a Long Bone. A typical long bone shows the gross anatomical characteristics of bone. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone. Red marrow fills the spaces in the spongy bone.
The flat bones of the face, most of the cranial bones, and a good deal of the clavicles (collarbones) are formed via intramembranous ossification, while bones at the base of the skull and the long bones form via endochondral ossification.
