Bone Types and Functions Assessment

The video tutorial explains the classification of bones in the human body, focusing on the axial and appendicular skeletons. It covers the functions of bones, such as support, movement, and protection, and describes the different shapes of bones: long, short, flat, irregular, and sesamoid. The video also discusses bone tissue types, including compact and cancellous bone, and explains the processes of bone development and ossification, highlighting intramembranous and endochondral ossification.

What are the two main divisions of the skeletal system?

• Axial and Appendicular

• Anterior and Posterior

• Cranial and Caudal

• Dorsal and Ventral

Which of the following is NOT a function of bones?

• Movement

• Support

• Protection

Which type of bone is characterized by having a length greater than its width?

• Flat bones

• Irregular bones

• Long bones

• Short bones

What is the primary function of sesamoid bones?

• To support body weight

• To store minerals

• To reduce friction in tendons

• To protect internal organs

Which bone type is primarily responsible for stabilizing joints like the wrist and ankle?

• Long bones

• Flat bones

• Short bones

• Irregular bones

What is the main characteristic of compact bone?

• It is lightweight and spongy

• It is dense and strong

• It is found only in the skull

• It contains red marrow

Which type of bone tissue is found in the core of short bones?

• Cancellous bone

• Compact bone

• Lamellar bone

• Woven bone

What is the term for the immature bone that forms initially during ossification?

• Compact bone

• Lamellar bone

• Woven bone

• Cancellous bone

Which ossification process involves bone forming directly from a membrane?

• Intramembranous ossification

• Endochondral ossification

• Periosteal ossification

• Epiphyseal ossification

What type of bones are formed through endochondral ossification?

• Cartilage bones

• Membrane bones

• Accessory bones

• Sesamoid bones
