Arteria nutricia

Arteria Nutricia refers to a group of blood vessels that supply nutrients to the bones. These arteries are essential for the health and maintenance of bone tissue. They are typically small in size and are found in all bones of the body.

Anatomy

The arteria nutricia enters the bone through a small hole known as the nutrient foramen. This foramen is usually located near the middle of the bone and is directed away from the growing end. Once inside the bone, the artery divides into ascending and descending branches that supply the marrow and inner parts of the bone.

Function

The primary function of the arteria nutricia is to provide nutrients to the bone. This includes supplying oxygen and essential nutrients to the bone cells, as well as removing waste products. In addition, these arteries play a crucial role in bone growth and repair.

Clinical Significance

Damage or blockage of the arteria nutricia can lead to serious health problems, including osteonecrosis, a condition characterized by the death of bone tissue due to a lack of blood supply. This can result in pain, bone collapse, and disability. Treatment options for osteonecrosis often involve surgery to restore blood flow to the affected bone.
