Study Notes
Bone Structure and Classification
- Axial Skeleton: Includes the skull, vertebral column, and rib cage; excludes the femur, clavicle, and scapula.
- Appendicular Skeleton: Comprises limbs and girdles; includes the humerus, but not ribs, sternum, or vertebrae.
- Patella: Classified as a sesamoid bone, important for knee joint function.
- Flat Bones: Example is the parietal bone; provides protection and support.
Bone Marrow and Cell Functions
- Hemopoiesis: The process of blood cell production in bone marrow.
- Red Bone Marrow: Typically found in the epiphyses of long bones in adults, involved in blood production.
- Yellow Bone Marrow: Primarily used for fat storage; does not produce blood cells.
Bone Cells
- Osteoblasts: Responsible for bone formation; create new bone tissue.
- Osteoclasts: Break down bone tissue, essential for bone remodeling and calcium resorption.
- Osteocytes: Maintain bone tissue; reside in small cavities called lacunae.
Cartilage and Bone Structure
- Articular Cartilage: Covers the epiphysis of long bones, allowing smooth joint movement.
- Periosteum: A dense connective tissue layer covering the external surface of bones, crucial for growth and repair.
- Endosteum: Lines inner surfaces of bone including the medullary cavity, involved in bone growth and repair.
Bone Formation and Growth
- Ossification: The process of bone formation from cartilage; includes endochondral and intramembranous ossification.
- Endochondral Ossification: Replaces hyaline cartilage with bone; important for long bone growth.
- Appositional Growth: Increases bone thickness and is essential for strengthening.
- Epiphyseal Plate: Involved in length growth of bones.
Fracture Repair and Hormonal Regulation
- Fracture Healing: Begins with hematoma formation, followed by fibrocartilaginous callus production and eventually a bony callus.
- Parathyroid Hormone: Increases blood calcium levels by stimulating osteoclast activity when calcium is low.
- Calcitonin: Inhibits osteoclast activity when calcium levels are high.
Mineral Storage and Hematopoiesis
- Lipids Storage: Yellow bone marrow in adults serves as storage for lipids.
- Hematopoiesis: Primarily occurs in red bone marrow.
Cell Anatomy and Functions
- Ribosomes: Sites for protein synthesis within the cell.
- Smooth vs. Rough Endoplasmic Reticulum (ER): Rough ER has ribosomes; involved in protein synthesis, whereas smooth ER produces lipids.
- Golgi Apparatus: Functions in protein and lipid packaging and distribution.
Cell Organelles
- Mitochondria: Known as the powerhouse of the cell; responsible for ATP production.
- Lysosomes: Contain enzymes for digesting waste and damaged organelles.
Cellular Processes
- Autolysis: Cell death initiated by the cell itself.
- Osmosis: The movement of water across a selectively permeable membrane, critical for maintaining cellular function.
