Skeletal System-General

Identify the functions of the periosteum.

• Provides nutrient supply to the bones.

• Membrane that lines the internal bone surfaces.

• Serves as attachment point for ligaments and tendons.

• Stores the cells responsible for making blood cells.

Identify the functions of the articular cartilage.

• Initiates calcification of bone.

• Houses the growth plate of bones.

• Reduces friction at the moveable joint.

• Absorbs shock.

Which type of cell are known as bone germinators? They make new osseus tissue by secreting collagen and organic components, then they initiate calcification.

• Osteoblasts

• Osteoclasts

• Chondroblasts

• Osteocytes

The process by which minerals crystalize around collagen fibers in the matrix of bone.

(a)  

Which describes Resorption?

• Intestinal absorption of calcium.

• The breakdown and release of calcium (and other minerals) into the blood.

• The process by which bones form.

• The process of osteoblasts maturing into osteocytes.

Which type of ossification forms the cranial bones, clavicles, flatbones, and closure of infant fontanels?

• Appositional

• Calcification

• Endochondral

• Intramembraneous

Bone growth in length relies on:

• The epiphyseal line.

• An active growth plate.

• Osteoblasts in the periosteum building new bone while at the same time osteoclasts in the endosteum breaking down bone.

• Ongoing replacement of old bone tissue with new bone tissue.

The process by which bones form.

(a)  

Identify the functions of the skeletal system.

• Production of blood cells.

• Storage of minerals and fats.

• Movement

• Protects internal organs from injury.
