Question 1: Name three main functions of the human skeleton.

Answer: Support of the body, protection of internal organs, and enabling movement through attachment points for muscles.

Question 2: Identify two bones found in the human skull.

Answer: The skull (cranium) and the mandible (jawbone).

Question 3: Describe the difference between a long bone and a flat bone, giving one example of each.

Answer: A long bone is longer than it is wide and provides support and movement, such as the femur. A flat bone is thin and flat, providing protection and surface area for muscle attachment, such as the sternum.

Question 4: Explain why the vertebral column is important for the human body.

Answer: The vertebral column supports the body’s weight, protects the spinal cord, and allows flexible movement.

Question 5: Identify the bones that make up the arm from shoulder to hand.

Answer: Humerus (upper arm), radius, and ulna (forearm), followed by the bones of the hand (carpals, metacarpals, phalanges).

Question 6: Describe the role of the rib cage in the human body.

Answer: The rib cage protects vital organs like the heart and lungs and supports the chest wall.

Question 7: Draw a simple sketch of the human skull, including the jawbone, eye sockets, and nasal cavity. Ensure your sketch shows the basic outline and key features.

Answer: A correct sketch should depict the shape of the skull with clearly marked eye sockets, a nasal cavity, and the jawbone attached at the bottom.

Question 8: List two joints in the human body and describe their movement type.

Answer: The elbow joint (hinge joint) allows bending and straightening; the shoulder joint (ball-and-socket joint) allows movement in multiple directions.

Question 9: Explain how the skeletal system works with the muscular system to produce movement.

Answer: Bones provide a rigid structure for attachment of muscles; when muscles contract, they pull on bones at joints, creating movement.

Question 10: Identify the bones involved in forming the knee joint.

Answer: The femur (thigh bone), tibia (shinbone), and patella (kneecap).
