2- Overview of the Skeletal System

A set of flashcards covering key terms and definitions related to the skeletal system.

Skeletal System

The system providing support, protection, assisting in movement, storing minerals, and producing blood cells.

Cartilage

A flexible connective tissue found at joints and formed from chondrocytes.

Osteocytes

Bone cells that lie in lacunae and are involved in the maintenance of bone tissue.

Compact Bone

A dense and highly organized type of bone tissue composed of osteons.

Spongy Bone

A lighter type of bone tissue that contains trabeculae and houses red bone marrow.

Trabeculae

Thin plates that make up the sponge-like structure of spongy bone.

Diaphysis

The shaft of a long bone containing the medullary cavity filled with yellow bone marrow.

Epiphysis

The expanded end of a long bone composed of spongy bone and containing red bone marrow.

Periosteum

Connective tissue that covers all bones and is continuous with ligaments and tendons.

Articular Cartilage

A thin layer of hyaline cartilage covering the epiphysis of bones at joints.

Endosteum

A thin membrane lining the medullary cavity of a bone.

Chondrocytes

Cells found in cartilage that lie within lacunae.

Hyaline Cartilage

A type of cartilage found at the ends of long bones, nose, and ribs.

Fibrocartilage

A type of cartilage found in intervertebral disks and the knee.

Elastic Cartilage

A type of flexible cartilage found in ear flaps and the epiglottis.

Tendons

Connective tissues that attach muscles to bones.
