The diagram below shows part of the human skeleton. 3.1 Name: (a) The part labelled X (b) The part labelled Y 3.2 State two functions of the axial skeleton. 3.3 Explain how ligaments and tendons differ in both structure and function.

Here are the answers to your questions:

3.1 Name:

• a) The part labelled X: Skull
• b) The part labelled Y: Pelvic girdle (or Pelvis)

3.2 State two functions of the axial skeleton.

• The axial skeleton protects vital organs such as the brain (by the skull), spinal cord (by the vertebral column), and heart and lungs (by the rib cage).
• It provides support for the body and maintains posture.

3.3 Explain how ligaments and tendons differ in both structure and function.

• Ligaments connect bone to bone and are elastic, allowing for flexibility and stabilizing joints.
• Tendons connect muscle to bone and are inelastic, transmitting the force of muscle contractions to move bones.
