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. That's 2 down. 3 left today — send the next one.
