Study Notes
Joints and Articulations
- Diarthrotic joints feature joint capsules and allow for significant movement.
- Ligaments are connective tissue bands that link bones, providing stability.
- A fully synarthrotic joint skeleton would have limited movement capabilities.
- Sutures in the skull are classified as synarthroses, indicating they are immovable.
- Cartilage serves as the connector in amphiarthrotic joints, allowing for slight movement.
- Ball and socket joints are the most mobile type of diarthrotic joints, facilitating a wide range of motion.
- Hinge joints are associated with synovial membranes, indicating they allow for bending movements.
Types of Joints
- Rank of joint mobility:
- Diarthrotic joints are the most movable.
- Amphiarthrotic joints allow limited movement.
- Synarthrotic joints are the least movable.
- Examples:
- Diarthrotic joint example includes the pubic symphysis.
- Synarthroses example includes the coronal suture.
Skeleton and Bone Composition
- Hematopoiesis, or blood cell formation, occurs in the epiphysis of long bones.
- Central canals within bones house blood vessels that supply the bone.
- Epiphysis refers to the ends of long bones.
- Osteoclasts are specialized cells responsible for bone resorption.
- Compact bones contain Haversian systems, vital for structural integrity.
Bone Development and Growth
- Endochondral ossification is the process where cartilage transforms into bone.
- At age two, bones typically contain more cartilage and have epiphyseal plates, allowing growth.
- Bone expands as long as cartilage remains in the epiphyseal plate.
- Osteoblasts are the bone-building cells that contribute to bone formation, residing in lacunae.
Functions of the Skeletal System
- Hematopoiesis is critical for producing blood cells.
- The skeletal system supports the body while maintaining flexibility for movement.
- Protection is provided to vital organs, such as the brain and heart.
- Movement occurs in collaboration with muscle contractions.
- Storage of essential minerals, like calcium, occurs within bones.
