The Skeletal System

This topic examines the structure and composition of skeletons, including types (hydrostatic, exoskeleton, endoskeleton), joints, and muscles. Learners will compare human and insect skeletons, describe synovial joints, and investigate skeletal disorders (e.g., arthritis, osteoporosis). Understanding the skeletal system is vital for ECZ questions on support, locomotion, and animal biology. It equips Zambian students with knowledge of body mechanics, common ailments, and first aid for injuries, supporting the CBC's focus on integrated science and health education.
