Bone Structure and Function Concepts

The video tutorial provides an in-depth explanation of bone histology, focusing on the structure of compact and spongy bones. It covers the components of compact bone, including lamellae, lacunae, and osteocytes, and details the Haversian system with osteons and canals. The tutorial also discusses different types of lamellae and the role of Volkmann's canals in connecting the bone's internal and external structures.

What is the outer covering of the compact bone called?

• Lacuna

• Periosteum

• Endosteum

• Marrow

What fills the spaces in the meshwork of spongy bone?

• Osteocytes

• Nerves

• Bone marrow

• Blood vessels

What are the sheets of bone called?

• Lacunae

• Canaliculi

• Lamellae

• Osteons

What is found within the lacunae?

• Marrow

• Nerves

• Blood vessels

• Osteocytes

What is the central canal in an osteon called?

• Endosteum

• Volkmann's canal

• Periosteum

• Haversian canal

What structure is made up of concentric lamellae?

• Lacunae

• Osteons

• Canaliculi

• Periosteum

Which type of lamellae is found between osteons?

• Interstitial

• Circumferential

• Periosteal

• Concentric

What connects the Haversian canals?

• Lamellae

• Osteocytes

• Volkmann's canals

• Lacunae

What is the function of Volkmann's canals?

• Transport nutrients

• Connect osteocytes

• Store marrow

• Support bone structure

Where is the circumferential lamellae located?

• Around the marrow

• Between the lacunae

• Below the periosteum

• Inside the osteons
