Bone Structure and Function Concepts

The video tutorial explains the structure and function of long bones, which are one of the five types of bones in the human body. It covers the different regions of long bones, including the epiphysis, diaphysis, and metaphysis, and describes the role of articular cartilage, spongy bone, and compact bone. The tutorial also discusses the growth process in the metaphysis and the protective and healing functions of the periosteum.

What are the three main regions of a long bone?

• Epiphysis, Metaphysis, Diaphysis

• Compact, Spongy, Marrow

• Articular, Cancellous, Cortical

• Cortex, Medulla, Periosteum

What is the primary function of articular cartilage?

• To produce blood cells

• To connect bone to joint

• To store fat

• To provide bone strength

What type of bone structure is found in the epiphysis?

• Compact bone

• Cancellous bone

• Osteon bone

• Cortical bone

Where does hematopoiesis occur in the long bone?

• In the periosteum

• In the red bone marrow

• In the yellow marrow

• In the compact bone

What is the role of the epiphyseal plate in children?

• To protect the bone

• To facilitate bone growth

• To produce red blood cells

• To store minerals

At what age does the epiphyseal plate typically stop growing?

• 30 years

• 25 years

• 21 years

• 18 years

What is the function of the medullary cavity?

• To connect muscles to bones

• To house the marrow

• To store adipose tissue

• To produce red blood cells

What is the primary role of the compact bone?

• To store fat

• To provide flexibility

• To give strength and support

• To produce white blood cells

What is the periosteum's role in bone health?

• To connect bones to joints

• To aid in bone growth and healing

• To store calcium

• To produce red blood cells

What type of cells are involved in bone growth and healing?

• Osteoclasts

• Fibroblasts

• Chondrocytes

• Osteoblasts
