Bone Tissue and Structure Concepts

The video tutorial explains the differences between compact and spongy bone, also known as cortical and trabecular bone, respectively. Compact bone is dense, providing support and protection, while spongy bone is porous, allowing for metabolic activity and housing red bone marrow. The video also covers the microscopic structures of both types, highlighting osteons in compact bone and trabeculae in spongy bone.

What are the two main types of bone tissue discussed in the video?

• Thick and Thin

• Hard and Soft

• Cortical and Trabecular

• Dense and Porous

Which type of bone tissue is known for its dense and smooth appearance?

• Trabecular bone

• Spongy bone

• Cortical bone

• Marrow bone

What is the primary function of compact bone?

• Providing support and protection

• Producing red blood cells

• Facilitating metabolic activity

• Storing fat

Which bone tissue type is more porous and allows for easier movement of minerals?

• Dense bone

• Compact bone

• Cortical bone

• Spongy bone

Where are red blood cells primarily produced?

• In the dense bone

• In the spongy bone

• In the compact bone

• In the cortical bone

What is the structural unit of compact bone called?

• Canaliculi

• Lamellae

• Osteons

• Trabeculae

What surrounds the Haversian canal in compact bone?

• Lamellae

• Volkmann canals

• Osteoblasts

• Trabeculae

What is the role of Volkmann canals in compact bone?

• To store calcium

• To connect osteons

• To produce red blood cells

• To provide flexibility

How do trabeculae in spongy bone adapt to mechanical load?

• By becoming denser

• By producing more bone marrow

• By changing their structural position

• By increasing their size

What type of cells are produced in the bone marrow within trabeculae?

• Osteoblasts

• Chondrocytes

• Fibroblasts

• Red and white blood cells
