Anatomy of a Long Bone. 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.

Anatomy of a Long Bone. A long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow. The walls of the diaphysis are composed of dense and hard ...

Jan 21, 2025 · Anatomy of Long Bones. Long bones have a complex and specialized structure designed to support and facilitate movement. They consist of several key components, including the diaphysis, epiphyses, metaphyses, medullary cavity, periosteum, and endosteum.

Long bone anatomy. A long bone is a bone that has greater length than width. A long bone has a shaft and 2 ends. Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and …

The long bones are those that are longer than they are wide. They are one of five types of bones : long, short , flat , irregular and sesamoid . Long bones, especially the femur and tibia , are subjected to most of the load during daily activities and they are crucial for skeletal mobility.

A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3.1). The diaphysis is the hollow, tubular shaft that runs between the proximal and distal ends of the bone. Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult.

Feb 27, 2025 · The structure of a long bone allows for the best visualization of all of the parts of a bone (Figure 5.3.1 5.3. 1). A long bone has five zones: the diaphysis, two metaphyses, and two epiphyses. The diaphysis is the narrow, tubular shaft that …

Jul 4, 2024 · Long bones contain yellow bone marrow and red bone marrow, which produce blood cells. The long bones are those that are longer than they are wide. They are one of five types of bones: long, short, flat, irregular, and sesamoid.

A long bone is a bone that has a shaft and 2 ends and is longer than it is wide. Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line.

The long bones have a long, central shaft that enlarges at the ends into epiphysis. The long bones in the legs are the femur, tibia, and fibula. The long bones of the arms are the radius and ulna. Both the feet and hands have long bones in the digits – the phalanges.
