Question

1 multiple choice 5 points osteogenesis is the process of _____. making a cartilage model of the fetal bone making collagen fibers for calcified cartilage bone formation bone destruction to liberate calcium 2 multiple choice 5 points the cell responsible for secreting the matrix of bone is the _____. osteocyte osteoclast osteoblast chondrocyte 3 multiple choice 5 points what can a deficiency of growth hormone during bone formation cause? increased mitosis of chondrocytes decreased osteoclast activity decreased proliferation of the epiphyseal plate cartilage

Explanation:

1. Osteogenesis is the process of bone formation. It is not about making a cartilage model, making collagen fibers for calcified cartilage, or bone destruction.
2. Osteoblasts are the cells responsible for secreting the bone - matrix. Osteocytes are mature bone cells, osteoclasts are for bone resorption, and chondrocytes are related to cartilage.
3. A deficiency of growth hormone during bone formation can cause decreased proliferation of the epiphyseal plate cartilage, which affects bone growth. It does not cause increased mitosis of chondrocytes or decreased osteoclast activity.

Answer:

1. bone formation
2. osteoblast
3. decreased proliferation of the epiphyseal plate cartilage
