Show answer & explanation
Correct answer: A — Ligament
Ligaments are strong bands of fibrous connective tissue that connect bones to other bones, stabilizing the joints.
Q2. The vertebral column is primarily responsible for which function?
Show answer & explanation
Correct answer: D — Supporting the trunk and protecting the spinal cord
The vertebral column forms the backbone, which supports the torso and protects the delicate spinal cord.
Q3. Which component provides structural support and protection to the body?
Show answer & explanation
Correct answer: A — Skeletal system
The skeletal system, composed of bones and cartilage, provides the framework for the body, offering support and protection to internal organs.
Q4. What is the primary function of the skeletal system in the human body?
Show answer & explanation
Correct answer: C — Support and protection
The main functions of the skeletal system are to provide structural support to the body and to protect vital internal organs.
Q5. Which type of joint allows movement in only one plane (like a door hinge)?
Show answer & explanation
Correct answer: C — Hinge joint
A hinge joint permits movement in only one plane, similar to the movement of a door hinge.
Q6. The vertebral column is primarily composed of which structures?
Show answer & explanation
Correct answer: B — Vertebrae
The vertebral column is the backbone, which is formed by a series of interconnected vertebrae.
Q7. Which of the following is the primary function of the skeletal system in the human body?
Show answer & explanation
Correct answer: B — Providing mechanical support and protection
The primary functions of the skeletal system include providing mechanical support for the body, protecting vital organs, and serving as an attachment site for muscles.
Q8. Which of the following structures is a major component of the skeletal system that provides structural support and protects internal organs?
Show answer & explanation
Correct answer: C — Bones
Bones form the rigid framework of the skeleton, providing the main structural support for the body and protecting vital internal organs. Joints are points of articulation, and ligaments/cartilage provide connection and cushioning.
Q9. What is the main composition of the bone tissue?
Show answer & explanation
Correct answer: A — Calcium salts and organic matrix
Bone tissue is a composite material consisting of a hard mineral phase (calcium salts) and a soft organic matrix (collagen fibers and proteins).
Q10. The dense, hard outer layer of most bones is primarily composed of which type of tissue?
Show answer & explanation
Correct answer: B — Compact bone
Compact bone (or cortical bone) forms the dense, strong outer layer of the bones.
Q11. Which of the following bones forms the upper arm of the human body?
Show answer & explanation
Correct answer: A — Humerus
The Humerus is the long bone that forms the upper arm of the limb.
Q12. What type of tissue makes up the bulk of the bones?
Show answer & explanation
Correct answer: A — Connective tissue
Bone tissue is a specialized type of connective tissue, characterized by its rigid structure and matrix.
Q13. Cartilage is a type of connective tissue that is found in the ends of bones and in joints. What is its main characteristic?
Show answer & explanation
Correct answer: D — It is flexible and resilient
Cartilage is flexible and resilient, providing smooth surfaces for joint movement and cushioning.
Q14. Flexibility and cushioning between bones are primarily provided by which tissue?
Show answer & explanation
Correct answer: A — Cartilage
Cartilage acts as a flexible cushion at the ends of bones and in joints, reducing friction during movement.
Q15. Bones that are thin, often curved, and serve primarily as protective coverings for internal organs are classified as:
Show answer & explanation
Correct answer: C — Flat bones
Flat bones (like the skull and sternum) are typically flat and provide extensive surface area for protection of underlying organs.
