Diaphyseal

Diaphyseal refers to the main or mid section (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat).

Anatomy[edit | edit source]

The diaphysis is the tubular, hollow shaft of a long bone. It is made up of dense, compact bone, also known as cortical bone. This type of bone is strong and durable, providing the necessary support and protection for the body.

The diaphysis contains the medullary cavity, which is filled with bone marrow and adipose tissue. The bone marrow is responsible for the production of blood cells, while the adipose tissue stores energy in the form of fat.

Function[edit | edit source]

The primary function of the diaphysis is to support the weight of the body and facilitate movement. The dense, compact bone of the diaphysis is able to withstand the stresses placed on it by the body's weight and movement.

In addition, the diaphysis serves as a site for muscle attachment. Muscles attach to the diaphysis via tendons, which allows for movement of the body.

Related Conditions[edit | edit source]

Certain medical conditions can affect the diaphysis of a long bone. These include:

Osteoporosis: This is a condition characterized by a decrease in bone density, which can lead to an increased risk of fracture. The diaphysis, being made up of dense, compact bone, can be particularly affected by osteoporosis.
Bone cancer: Certain types of bone cancer can originate in the diaphysis. These include osteosarcoma and Ewing's sarcoma.
Bone fractures: Fractures can occur in the diaphysis due to trauma or stress. These are often serious injuries that require medical attention.
