What guarantees the function of the skeleton as a mineral reserve?
Bone remodelling
Bone growth occurs after closure of the epiphysis plate.
False
Bone is a static organ composed of an inorganic extracellular matrix.
False
Bone remodelling serves to guarantee the function of the skeleton as a mineral reserve.
True
Both growth and modelling require only bone formation to occur at anatomically separate locations.
False
Immobilization increases resorption in bone remodelling.
True
Bone remodelling ends with the replacement of primary by secondary bone and does not continue throughout life.
False
Nutrition and exercise inhibit resorption in bone remodelling.
True
Calcitonin stimulates resorption in bone remodelling.
False
PTH stimulates resorption in bone remodelling.
True
Bone remodelling allows repair, rearrangement, and reorganization in cortical bone tissue.
False
Match the following bone cell activities with their responsibilities:
Osteoblastic activity = Bone formation Osteoclastic activity = Bone resorption Coupling or rotation = Basis for bone turnover or remodelling Modelling = Responsible for maintaining the characteristic morphology of growing bone
Match the following factors involved in bone remodelling with their effects:
Endogenous (hormonal) = PTH stimulates resorption and calcitonin inhibits resorption Environmental = Nutrition and exercise inhibit resorption. Immobility increases resorption Bone remodelling = Serves to guarantee the function of the skeleton as a mineral reserve, help maintain functions and fluid exchange in cortical bone tissue, and allow repair, rearrangement, and reorganization in trabecular bone tissue
Match the following descriptions with their corresponding bone characteristics:
Dynamic organ = Composed of an inorganic extracellular matrix and constantly being modified by osteoblasts and osteoclasts Cortical bone tissue = Functions as a mineral reserve and requires help to maintain functions and fluid exchange Trabecular bone tissue = Allows repair, rearrangement, and reorganization Primary bone = Replaced by secondary bone but bone remodelling continues throughout life
Match the following hormones with their effects on bone remodelling:
PTH = Stimulates resorption Calcitonin = Inhibits resorption Nutrition and exercise = Inhibit resorption Immobility = Increases resorption
Match the following descriptions with their roles in bone remodelling:
Nutrition and exercise = Inhibit resorption Immobilization = Increases resorption PTH = Stimulates resorption Calcitonin = Inhibits resorption

osteoclasts
Endogenous (hormonal): ______ stimulates resorption and calcitonin inhibits resorption.
PTH
