Ch6_-_The_Skeletal_System

What are the primary functions of the skeletal system?

Support, storage of minerals and lipids, blood cell production.

What is the role of the skeletal system regarding protection?

Protection of vital organs.

What role does leverage play in the skeletal system?

It works with muscles to facilitate movement.

What is ossification?

The process of bone formation during embryonic development.

What are the two types of ossification?

Intramembranous ossification and endochondral ossification.

What distinguishes compact bone from spongy bone?

Compact bone is solid and forms the walls of the diaphysis.

What is spongy bone's structure?

It has an interlacing network of bony rods and fills the epiphyses.

What are osteocytes?

Mature bone cells that maintain bone structure.

How do osteocytes maintain bone structure?

They recycle calcium salts.

What is the role of osteoblasts?

They produce new bone through the process of ossification.

What happens during bone remodeling?

Osteocytes maintain the matrix.

What occurs when osteoclasts are involved?

They remove matrix.

How do osteoblasts contribute to bone remodeling?

They build matrix.

What is the total number of major bones in the human skeleton?

206 major bones.

What are the two divisions of the skeletal system?

Axial skeleton and appendicular skeleton.

What is the structure and function of synovial joints?

They allow for free movement.

What role does the synovial membrane play?
