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). Long bones function as levers; they move when muscles contract.

Is the radius bone a short bone?
Long bones: Long bones have a tubular shaft and articular surface at each end. The major bones of the arms (humerus, radius, and ulna) and the legs (the femur, tibia, and fibula) are all long bones. ... The short bones include all of the metacarpals and phalanges in the hands, and the metatarsals and phalanges in the feet.
Which bones are long bones?
Long bones are so-called because they are longer than they are wide. Long bones in the arm include the humerus, radius, ulna, metacarpals, and phalanges. Long bones of the leg include the femur, tibia, fibula, metatarsals, and phalanges.
Is the radius a long short flat or irregular bone?
Most of the limb bones are long bones—for example, the femur, tibia, ulna, and radius. ... These bones may have short, flat, notched, or ridged surfaces. Examples of irregular bones are the vertebrae, hip bones, and several skull bones. Sesamoid bones are small, flat bones and are shaped similarly to a sesame seed.
What are the short bones?
Short bones include the carpal bones of the hands that allow movement of the wrist, and the tarsal bones of the feet that allow movement of the ankle. Short bones are shaped roughly as a cube and contain mostly spongy bone. The outside surface is comprised of a thin layer of compact bone.
Is the radius a long bone?
The radius is a long bone, one of the four types of bone in the body. A long bone is a dense, strong bone characterized as being longer than it is wide. The shaft is known as the diaphysis and the end of a long bone is called an epiphysis.
What's a radius bone?
radius, in anatomy, the outer of the two bones of the forearm when viewed with the palm facing forward. All land vertebrates have this bone. ... The head of the radius is disk-shaped; its upper concave surface articulates with the humerus (upper arm bone) above, and the side surface articulates with the ulna.
Which is a long bone?
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 bones are long short flat and irregular?
Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs. Irregular bones such as those of the face have no characteristic shape.
What bones are flat bones?
Flat bones are made up of a layer of spongy bone between two thin layers of compact bone. They have a flat shape, not rounded. Examples include the skull and rib bones. Flat bones have marrow, but they do not have a bone marrow cavity.
Is ribs a long bone?
In vertebrate anatomy, ribs (Latin: costae) are the long curved bones which form the rib cage, part of the axial skeleton. In most tetrapods, ribs surround the chest, enabling the lungs to expand and thus facilitate breathing by expanding the chest cavity.
Is metacarpal a long bone?
The metacarpal bones are five long bones of the hand between the carpal bones and the proximal phalanges of the hand that make up most of the palm.
What is a compact bone?
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. ... In compact bone, the haversian systems are packed tightly together to form what appears to be a solid mass.
What is short bones function?
Short bones have very equal proportions and are roughly shaped like a cube. Examples can be found in the bones of your wrists and ankles. Short bones provide stability to the wrist and ankle joints and also help facilitate some movements.
