Skeletal System: Part 1

Practice vocabulary flashcards reviewing the types and growth of cartilage, axial and appendicular skeletal divisions, bone shapes, and functions of bones.

Appositional growth

A type of cartilage growth where new matrix is laid on the surface of the cartilage.

Interstitial growth

A type of cartilage growth where new matrix is made inside the cartilage.

Hyaline cartilage

The most abundant type of cartilage, providing support and resilience with collagen fibers; located in joints and ribs.

Elastic cartilage

A type of cartilage that provides support and flexibility, found in the ear.

Fibrocartilage

A type of cartilage containing thick collagen fibers that provides tensile strength; found in the pubic symphysis and intervertebral discs.

Axial skeleton

The division of the skeleton comprising the skull bones, the vertebral column (vertebrae and sacrum), and the thoracic (rib) cage (sternum and ribs).

Appendicular skeleton

The division of the skeleton consisting of the limbs.

Shapes of bones

The four classifications of bone shapes: long, short, flat, and irregular.

Anchorage

A skeletal function where bones serve as levers for muscle action.

Mineral storage

A skeletal function that serves as a reservoir for minerals, specifically calcium storage.

Blood cell formation (hemapoiesis)

A primary function of bones involving the production of blood cells.

Triglyceride storage

A bone function that serves as fat storage.

Hormone production

A bone function involved in regulating insulin and maintaining glucose homeostasis.
