Questions and Answers

Match the bone type with its characteristic:

Long bone = Possesses a diaphysis and epiphyses Flat bone = Thin and curved; provides broad surfaces for muscle attachment Short bone = Cube-shaped; found in the wrist and ankle Irregular bone = Complex shape; vertebrae

Match the skeletal system component with its primary function:

Bones = Provide structural support and protection Cartilage = Reduces friction in joints Ligaments = Connect bones to bones Tendons = Connect muscles to bones

Match the bone cell type with its function:

Osteoblast = Forms new bone tissue Osteoclast = Breaks down bone tissue Osteocyte = Maintains bone matrix Osteogenic cell = Precursor to osteoblasts

Match the process with its description regarding bone development:

Intramembranous ossification = Direct formation of bone from mesenchymal tissue Endochondral ossification = Replacement of cartilage by bone Bone remodeling = Continuous process of bone resorption and formation Epiphyseal plate activity = Bone growth in length Signup and view all the answers

Flashcards

Vertebral Column

A structure that provides support and flexibility for the body.

Rib Cage

Protects the heart and lungs, assists in respiration.
