Mammalian Skeleton Functions: Support, Protection & Storage

Functions of the mammalian skeleton:

1. Support: Structural framework against gravity; maintains body shape; enables movement.
2. Protection: Skull protects brain; vertebrae protect spinal cord; ribcage protects heart, lungs, thoracic organs.
3. Storage: Minerals (calcium, phosphorus) for physiological processes.
4. Blood Cell Production: Bone marrow produces red blood cells (erythropoiesis), white blood cells (leucopoiesis), platelets (thrombopoiesis).
5. Mobility: Muscle-bone-joint interaction; muscle contraction pulls bones → movement.
6. Mineral Homeostasis: Reservoir for calcium/phosphate; releases/stores to maintain blood balance.
7. Heat Production: Bone marrow generates heat for temperature regulation.
8. Sense of Hearing: Middle ear ossicles transmit sound vibrations.
