Essentials of Bone Composition and Functions Quiz

Bone marrow is a spongy tissue found inside bones where blood cell formation or hematopoiesis occurs.

A condyle refers to a specific anatomical feature found in the skeletal system of animals, particularly humans. It is not related to trees, stones, or musical instruments.

An epicondyle is specifically a projection found on or above a condyle, usually in reference to a bone.

A fossa in anatomical terms refers to a shallow depression or cavity on the surface of a bone, typically for articulation with another bone.

The 'neck' in this context specifically refers to the anatomical structure at the juncture between the head of a long bone and the shaft, characterized by its narrowness.

Cartilage is a type of strong flexible connective tissue that cushions joints and provides structure to the body.

Osteocytes are mature bone cells responsible for maintaining the mineral content of the bone tissue.

The diaphysis refers to the central shaft of a bone, which is typically the longest and strongest portion of a long bone.

The epiphysis refers to the end part of a long bone where growth occurs, characterized by a widening section that contributes to the bone's overall length.

Long bones are a type of bone that have a characteristic elongated shape, with their length being greater than their width. They primarily function to support the body and provide leverage for movement.

Osteoblasts are responsible for bone formation and are considered immature bone cells, not mature bone cells, muscle cells, or nerve cells.

Articular cartilage is a specialized type of connective tissue that covers the ends of bones where they articulate with each other. Its main function is to reduce friction and absorb shock in joints.

Flat bones are typically thin and plate-shaped, providing protection and support. Examples include the sternum, scapulae, and pelvis. The other options provided don't accurately describe the characteristic of flat bones.

Spongy bone, also known as cancellous bone, is a type of bone tissue that is found inside the bone and has spaces within it. This characteristic allows for flexibility and shock absorption.

A fissure is a narrow opening or crack in a surface, often occurring in rock formations or the skin.

A sinus is a hollow cavity within a bone in the human body, typically associated with the nasal passage or skull structure.

Compact bone refers to the dense or hard exterior of surface bone, providing strength and protection.

Irregular bones do not have a uniform shape like long bones or flat bones. They often have complex shapes and serve unique functions in the body, such as protecting internal organs or providing structural support.

The medullary cavity is the central cavity of bone shafts where yellow or red bone marrow is stored.

In anatomy, a process refers to a bony projection on bone.

A foramen is a specific anatomical term referring to a hole or opening in a bone that allows nerves and blood vessels to pass through. It is not a bone, muscle, or organ.

The periosteum is a connective tissue membrane that covers bones, providing support and nourishment. It is not the outer layer of the skin, a fluid-filled sac near a joint, or soft tissue connecting muscle to bone.

Short bones are defined by their approximate equal length and width, providing a cube-like appearance. Examples include carpals and tarsals, which fit this description.

Yellow bone marrow primarily serves as an energy reserve in the form of fat, and it is located in the medullary cavity of long bones.

Cortical bone is the dense or hard exterior surface of bone, providing structure and protection.

The correct definition of 'head' in this context refers to the large, smooth, ball-shaped end on a long bone. It is a specific anatomical term.

Cancellous bone, also known as spongy bone, is the internal tissue of the bone that provides structural support. It is different from compact bone, which is the hard outer layer of the bone.
