What are the 3 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.
- distal epiphysis.
- proximal epiphysis.
What is the structure and function of a long bone?
Long bones function to support the weight of the body and facilitate movement. Long bones are mostly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the upper limbs (the humerus, radius, ulna, metacarpals, and phalanges).
What are the 5 major parts of a long bone?
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 is long bone called?
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.
What is the longest bone in human body?
The femur is one of the most researched bones in the human anatomy and forensic medicine. As the longest bone in the human body, it is well preserved in skeletal remains.
What is spongy bone called?
Cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance.
What are the 6 classifications of bones?
The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 1).
What makes up the bone give at least 10?
Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong.
What are the major types of bone markings?
There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”).
What are the major parts of 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.
What is the basic structure of a bone?
As shown in Figure below, the basic structure of bones is bone matrix, which makes up the underlying rigid framework of bones, composed of both compact bone and spongy bone. The bone matrix consists of tough protein fibers, mainly collagen, that become hard and rigid due to mineralization with calcium crystals.
What is the inside of a bone called?
Bone Marrow The inside of your bones are filled with a soft tissue called marrow. There are two types of bone marrow: red and yellow. Red bone marrow is where all new red blood cells, white blood cells, and platelets are made.
What is Osteon?
Osteon, the chief structural unit of compact (cortical) bone, consisting of concentric bone layers called lamellae, which surround a long hollow passageway, the Haversian canal (named for Clopton Havers, a 17th-century English physician).
What is the deepest part of the bone?
The outside of the bone consists of a layer of connective tissue called the periosteum. Additionally, the outer shell of the long bone is compact bone, then a deeper layer of cancellous bone (spongy bone ) which contains in the medullary cavity the bone marrow.

What are bone forming cells called?
Osteoblasts, bone lining cells and osteoclasts are present on bone surfaces and are derived from local mesenchymal cells called progenitor cells. Osteocytes permeate the interior of the bone and are produced from the fusion of mononuclear blood-borne precursor cells.
