Skeletal System Assignment 2

What is the function of hyaline cartilage located on the end of long bones?

• To protect bone ends at the joint

• To provide flexibility to the bone

• To house yellow marrow

• To lengthen the bone

Which type of bone cells secrete the matrix for bone formation?

• Osteogenic cells

• Osteoblasts

• Osteocytes

• Osteoclasts

Where is red bone marrow located in adults?

• In the diaphysis of long bones

• In the epiphysis of long bones

• In the spongy bone of flat bones

• In the compact bone of irregular bones

What is the function of the periosteum?

• To cover the external surface of bone

• To line the internal surface of bone

• To provide flexibility to the bone

• To house yellow marrow

Which type of bone growth occurs through appositional growth?

• Growth in length

• Growth in width

• Growth in thickness

• Growth in density

What is the role of hormones in bone remodeling?

• To maintain blood calcium homeostasis

• To stimulate bone growth in length

• To regulate bone growth proportions

• To repair bone fractures

According to Wolff's Law, how does bone respond to mechanical stress?

• By growing thicker along the diaphysis

• A bone grows or remodels in response to the demands placed on it.

• By developing large bony projections

• By increasing bone resorption

What is the first stage of bone repair after a fracture?

• Hematoma formation

• Fibrocartilaginous callus formation

• Bony callus formation

• Remodeling of bony callus

What is the main cause of osteoporosis?

• Insufficient calcium intake

• Vitamin D deficiency

• Bone resorption outpaces bone deposit

• High ratio of spongy to compact bone

What is the characteristic feature of Paget's disease?

• Bones inadequately mineralized

• Excessive and haphazard bone deposit and resorption

• High ratio of compact to spongy bone

• Bone mass reduced
