- 1. Skeletal System By: Group 5 Atom
- 2. Introduction The term "skeletal" generally relates to the skeleton, which is the internal framework of bones in vertebrates.
- 3. The skeletal system consists of several key parts: 1. Bones: The rigid structures that form the skeleton, providing support and protection. 2. Cartilage: Flexible tissue found in joints, the nose, and ears, which cushions bones and aids in movement. SKELETAL SYSTEM
- 4. SKELETAL SYSTEM 3. Ligaments: Strong connective tissues that connect bones to other bones, stabilizing joints. 4. Tendons: Connective tissues that attach muscles to bones, enabling movement. 5. Joints: Areas where two or more bones meet, allowing for various ranges of motion. These components work together to support the body, protect vital organs, and enable movement.
- 5. PARTS OF THE SKELETON 1. Axial Skeleton: Comprises the skull, vertebral column (spine), and rib cage. It supports the central axis of the body. • Skull: Protects the brain and forms the structure of the face. • Vertebrae: Protects the spinal cord and supports the head. • Rib Cage: Protects the heart and lungs.

- 6. PARTS OF THE SKELETON 2. Appendicular Skeleton: Includes the bones of the limbs and girdles (shoulder and pelvic). • Shoulder Girdle: Composed of the clavicle and scapula, connecting the upper limbs to the body. • Upper Limbs: Includes the humerus, radius, and ulna, as well as the bones of the hand. • Pelvic Girdle: Connects the lower limbs to the body. • Lower Limbs: Composed of the femur, tibia, fibula, and bones of the foot.

- 8. FUNCTIONS OF THE SKELETON • Support: Provides structure and support for the body. • Protection: Shields vital organs (e.g., brain, heart). • Movement: Works with muscles to facilitate movement. • Mineral Storage: Stores minerals like calcium and phosphorus. • Blood Cell Production: Bone marrow produces red and white blood cells.
