Section D – Match the Following (Explained)

1–Skull → Protects brain
2–Rib cage → Protects heart and lungs
3–Femur → Longest bone
4–Brain → Controls body activities
5–Backbone → Made of vertebrae
6–Nerves → Carry messages

Section E – One Word / Very Short Answers (Explained)

  1. Joint – Place where two bones meet.
  2. Ball and socket joint – Found in the shoulder.
  3. Brain – Soft organ inside the skull.
  4. Motor nerves – Carry messages from brain to muscles.
  5. Spinal cord – Connects brain and nerves.
  6. Femur – Longest bone of the leg.

Section F – Long Answer Questions (Detailed Answers)

  1. The skeletal and muscular systems work together to produce movement. Muscles are attached to bones. When muscles contract and relax, they pull the bones, allowing actions like walking, running, and lifting objects.
  2. Hinge joints allow movement in one direction, such as the knee and elbow. Ball and socket joints allow movement in all directions, such as the shoulder. Pivot joints help rotate the head, while fixed joints do not allow movement.
  3. The spinal cord controls reflex actions. When we touch something hot, sensory nerves carry the message to the spinal cord, which immediately sends a response through motor nerves without involving the brain.
  4. The cerebrum controls thinking, memory, and voluntary actions. The cerebellum maintains balance and coordination. The spinal cord carries messages between the brain and the rest of the body.
  5. The skeleton protects organs like the brain, heart, and lungs. It also helps maintain posture and keeps the body upright.

Section G – Case-Based Questions (Detailed Answers)

Case Study 1:

  1. Nervous system.
  2. Sensory nerves.
  3. It was a reflex action to protect the body.
  4. Spinal cord.

Case Study 2:

  1. Skeletal system.
  2. Plaster keeps the bone steady so it can heal.
  3. Proper nutrition provides calcium and vitamins for bone healing.
  4. Femur or knee joint bone.

Section I – HOTS Answers

  1. A plaster cast keeps broken bones in position so new bone tissue can form properly.
  2. Without joints, the body would be stiff and unable to move or perform daily activities.

Section J – Additional MCQs Answers

  1. Spinal cord
  2. Pivot joint
  3. Pulling hand away from fire
  4. Cerebellum
  5. Bones contain bone marrow
  6. Motor nerves

Section K – Application-Based Answers

  1. The knee has a hinge joint, and injury makes movement painful.
