The sternum is a partially T-shaped vertical bone that forms the anterior portion of the chest wall centrally. The sternum is divided anatomically into three segments: manubrium, body, and xiphoid process. The sternum connects the ribs via the costal cartilages forming the anterior rib cage. The manubrium is the broad superior segment, the body is the middle portion, and the xiphoid process is a narrower distal segment forming the partial T-shape. The anatomical position and variations make the sternum an important bony structure of surgical significance. In addition to the anatomy of the sternum, clinical and forensic implications of the sternum are also topics in this article.

Primary ossification center forms in the diaphyseal region of the periosteum called the periosteal collar. Secondary ossification centers develop in the epiphyseal region after birth.What are two membranous sites of Osteoprogenitor cells? ›
Periosteum and endosteum contain cells (osteoblasts, osteoclasts, and osteoprogenitor cells) required for bone development and remodeling of the bone.What is common to find in compact bone? ›
Lamellae and E. Central Canals are primarily found in compact bone but not in spongy bone. Lamellae are concentric rings made up of hollow tubes of bone matrix. On the other hand, central canals contain small blood vessels that pass through the core of each osteon.Where is red bone marrow found in an adult quizlet? ›
In adults red marrow is found only in selected portions of the axial skeleton such as flat bones of the skull, vertebrae, ribs sternum and ossa coxae (hip bone).What is the secondary ossification center? ›
A secondary ossification center is the area of ossification that appears after the primary ossification center has already appeared – most of which appear during the postnatal and adolescent years. Most bones have more than one secondary ossification center. In long bones, the secondary centers appear in the epiphyses.What are the 3 stages of bone development? ›
Answer and Explanation: Bone development occurs in 3 stages, intramembranous ossification, endochondral ossification, and then remodeling. Intramembranous ossification and endochondral ossification occur during the fetal stage of development.What are sites where two bones meet? ›
Joints are where two bones meet. They make the skeleton flexible — without them, movement would be impossible. Joints allow our bodies to move in many ways.What are the names and locations of the 2 membranes found on long bones? ›
The medullary cavity has a delicate membranous lining called the endosteum (end- = “inside”; oste- = “bone”), where bone growth, repair, and remodeling occur. The outer surface of the bone is covered with a fibrous membrane called the periosteum (peri– = “around” or “surrounding”).What are the two bone membranes? ›
The periosteum is the sheath outside your bones that supplies them with blood, nerves and the cells that help them grow and heal. The endosteum is a membrane that lines the center of your bones that contain bone marrow.Where can you find bone marrow? ›
Bone marrow is a spongy substance found in the center of the bones. It manufactures bone marrow stem cells and other substances, which in turn produce blood cells. Each type of blood cell made by the bone marrow has an important job. Red blood cells carry oxygen to tissues in the body.
It can be found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or Haversian system.What are the most common types of bones in the body? ›
- Long bone – has a long, thin shape. ...
- Short bone – has a squat, cubed shape. ...
- Flat bone – has a flattened, broad surface. ...
- Irregular bone – has a shape that does not conform to the above three types.
Red marrow is found mainly in the flat bones, such as the hip bone, sternum (breast) bone, skull, ribs, vertebrae, and shoulder blades, as well as in the metaphyseal and epiphyseal ends of the long bones, such as the femur, tibia, and humerus, where the bone is cancellous or spongy.What are 2 locations in which you would expect to find red bone marrow? ›
In adults, red bone marrow only persists in the axial flat bones (cranial bones, clavicle, sternum, ribs, scapula, vertebrae, and pelvis) and the proximal ends of the humerus and femur.Where is red bone marrow most commonly located? ›
Red bone marrow is primarily found in the medullary cavity of flat bones such as the sternum and pelvic girdle. This type of bone marrow contains hematopoietic stem cells, which are the stem cells that form blood cells.Where is the center of bone formation? ›
Epiphyseal plate of the long bone cartilage is a major center for growth, and in fact, this cartilage is responsible for almost all the long growths of the bones. This is a layer of hyaline cartilage where ossification occurs in immature bones.What are the first ossification centers? ›
The first bones to ossify are the capitate and hamate, and this occurs during the first year of life. The triquetral is next to appear arising during the third year of life and the lunate appears on the fourth year of life.Where does bone formation begin? ›
Bone of the first type begins in the embryonic skeleton with a cartilage model, which is gradually replaced by bone. Specialized connective tissue cells called osteoblasts secrete a matrix material called osteoid, a gelatinous substance made up of collagen, a fibrous protein, and mucopolysaccharide, an organic glue.What are the 5 stages of bone remodeling? ›
The remodelling cycle occurs within the basic multicellular unit and comprises five co-ordinated steps; activation, resorption, reversal, formation and termination. These steps occur simultaneously but asynchronously at multiple different locations within the skeleton.
