Skeletal System and Bone Anatomy Quiz

Study Notes

Functions of the Skeletal System

Provides support and structure to the body.
Facilitates movement by serving as attachment points for muscles.
Protects vital organs, such as the heart, lungs, and brain.
Stores minerals like calcium and phosphorus.
Houses bone marrow, where blood cell production occurs.

General Features of Bone

Composed of a dense connective tissue matrix.
Contains cells such as osteoblasts, osteocytes, and osteoclasts.
Has a rich blood supply and nerve endings.
Exhibits a layered structure with compact and spongy bone regions.

Function of the Extracellular Matrix in Bone

Provides structural support and rigidity to the bone.
Serves as a reservoir for key minerals, aiding in bone strength.
Facilitates communication and nutrient transfer between bone cells.
Affects the biomechanical properties of bone, influencing flexibility and resilience.

Bone Ossification

The process by which bone tissue forms.
Involves two main types: intramembranous ossification (directly from mesenchyme) and endochondral ossification (from cartilage).
Essential during fetal development and growth in children.
Plays a key role in healing fractures and adapting bone density with physical activity.

Part of the Skeleton Protecting the Brain

The skull, also known as the cranium, encases and protects the brain.
Comprised of several bones fused together for stability.
Features openings (foramina) for nerves and blood vessels while maintaining overall protection.
