What is the gross anatomy of a typical long bone?

Gross Anatomy of 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.

What are the 3 parts of a typical long bone?

Long bones are longer than they are wide. They can be divided into three regions – epiphysis, metaphysis and the diaphysis. The epiphysis contains the spongy bone (also called cancellous), which in turn contains the red bone marrow that is responsible for synthesizing blood cells.

What is a long bone in anatomy?

Long bones are hard, dense bones that provide strength, structure, and mobility. The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length. This is due to the shape of the bones, not their size.

What are the five anatomical structures of a long bone?

Terms in this set (15) List five major parts of a long bone. The major parts of a long bone include epiphysis, articular cartilage, diaphysis, periosteum, medullary cavity, endosteum, and marrow.

What do osteons make up?

Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.

What are the 5 major parts of a long bone?

List five major parts of a long bone. Epiphysis, diaphysis, periosteum, yellow marrow, medullary cavity, compact bone, spongy bone, articular cartilage.

What are the 4 parts of the long bone?

Examples of long bones include the femur, tibia, radius and ulna.

• Epyphysis. Every long bone is capped with wide areas on each end which are called epiphyses.
• Diaphysis. The largest part of any long bone is the long cylindrical middle, called the diaphysis.
• Metaphysis.
• Medullary Cavity.

Which are long bones?

Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities. Long bones include bones of the thigh, leg, arm, and forearm.

What are the 6 parts of a long bone?

• parts of a long bone.
• metaphysis. Part of the bone between the epiphysis and the diaphysis; it contains the connecting cartilage enabling the bone to grow, and disappears at adulthood.
• diaphysis.
• distal epiphysis.
• proximal epiphysis.
• metaphysis.

Which of the following bones listed is an example of a long bone?

Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges).
