Question 3 of 5
What is the skeletal system?
Correct Answer: D
Rationale: The skeletal system includes all bones (206 in adults) and connective tissues (e.g., cartilage, ligaments, tendons) that link them, supporting and protecting the body. A is incomplete, B and C describe muscular or organ systems, making 'All the bones in the body and the tissues that connect them' correct.
Question 4 of 5
What is the difference between cartilage and bone?
Correct Answer: B
Rationale: Cartilage is flexible and rubbery (e.g., ear), while bone is rigid and firm due to mineralization. Bone isn’t primitive (both are ancient), and both are internal, making 'Cartilage is rubbery, and bone is firm' correct.
Question 5 of 5
One of the following is not a function of the skeletal system
Correct Answer: C
Rationale: The skeletal system has several key functions: producing blood cells (hematopoiesis) in the bone marrow, storing minerals like calcium and phosphorus, and protecting vital organs (e.g., skull protects the brain, rib cage protects the heart and lungs). However, storing carbohydrates is not a function of the skeletal system; carbohydrate storage primarily occurs in the liver and muscles as glycogen.
