Skeletal System Quiz

What is one of the primary functions of the skeletal system related to support?

• Protect organs by acting as a barrier

• Provide framework for attachment of soft tissues & organs

• Store energy reserves in yellow marrow

• Produce red blood cells in red marrow

Where are energy reserves stored in the skeletal system?

• Red marrow

• Yellow marrow

• Bone matrix

• Osteocytes

What is the process by which cartilage hardens into bone?

• Osteogenesis

• Ossification

• Osteolysis

• Calcification

What type of bone is described as having an open network called trabeculae?

• Osteon Bone

• Marrow Bone

Which type of bone cell is responsible for building bones?

• Osteocytes

• Osteoclasts

• Osteoblasts

• Osteons

What is the role of osteoclasts in bone tissue?

• Secrete organic components
