5.1: Bones of the Skull
-
This page summarizes the division of the human skeleton into the axial skeleton, comprising the skull, vertebral column, and throat/inner ear bones, and the appendicular skeleton, which includes the limbs. The skull's rigid bones are held together by sutures, with the mandible being movable. Cranial bones protect the brain, while facial bones enhance the skull's structure.

5.2: The Vertebral Column
-
This page discusses the hyoid bone, a U-shaped bone in the neck essential for speech and tongue movement, and often fractured in strangulation. It also describes the vertebral column, which has 24 vertebrae categorized into cervical, thoracic, and lumbar regions, plus the sacrum and coccyx.

5.3: The Thoracic Cage – Ribs and Sternum
-
This page details the thoracic cage, part of the axial skeleton that safeguards the heart and lungs. It includes twelve rib pairs, a sternum, and thoracic vertebrae. True ribs (1-7) attach directly to the sternum, while false ribs (8-12) connect indirectly or are floating. The sternum is made up of the manubrium, body, and xiphoid process, highlighting the significance of these components in anatomical studies.

5.4: Exercises
-
This page details a lab focused on human anatomy, specifically the skeletal system. It includes exercises for students to identify bone components like ribs and limb bones, emphasizing anatomical features. The activities aim to enhance understanding of bone positioning with simpler terminology. An exercise is also included for determining the sex of a pelvis based on specific criteria.

5.5: MODELS- Bones
-
This page provides a detailed lab list for identifying bones and landmarks in the skull and spine, organized by difficulty. It includes descriptions of key bones (parietal, temporal, mandible) and landmarks (mastoid process, cranial sutures, foramen) as well as vertebrae types (cervical, thoracic, lumbar) and the sternum. The summary also addresses spinal curves and rib classification, offering a comprehensive resource for studying skeletal anatomy.
