Study Notes
Joint Functions and Classification
- Joints connect bones and enable various degrees of skeletal movement.
- Joint names often derive from the bones involved, such as the radioulnar joint.
Functional and Structural Joint Classifications
- Joints classified based on how bones bind together and range of movement:
- Synarthrotic: Immovable joints; examples include sutures and synchondroses (hyaline cartilage).
- Amphiarthrotic: Slightly movable joints; examples include symphyses (fibrocartilage) and syndesmoses (ligament-bound).
- Diarthrotic: Freely movable joints; include synovial joints like ball and socket, hinge, and pivot.
Fibrous Joints
- Gomphoses: Peg-in-socket joints (e.g., teeth anchoring into the jaw).
- Syndesmoses: Bones connected by long collagen fibers; examples include tibia-fibula and radius-ulna.
- Sutures: Fibrous tissue connecting skull bones; can ossify with age into synostoses.
Cartilaginous Joints
- Symphysis: Bones joined by fibrocartilage; e.g., intervertebral discs.
- Synchondrosis: Bones joined by hyaline cartilage; common in growth plates.
Synovial Joints and Components
- Synovial Joints: Contains fluid-filled joint cavities permitting diarthroses.
- Synovial Fluid: Viscous fluid derived from blood filtration; reduces friction and nourishes articular cartilage.
- Joint Capsule: Tough fibrous structure surrounding joints for strength and protection.
Hormonal Regulation of Bone Metabolism
- Parathyroid hormone (PTH) regulates blood calcium levels, promotes bone resorption.
- Calcitriol (active Vitamin D) enhances calcium absorption in the intestines.
- Calcitonin counters bone breakdown.
- Sex hormones (estrogen, testosterone) promote bone formation and mass.
Bone Remodeling and Calcium Homeostasis
- Bones serve as the body's main reservoir for calcium, stored as hydroxyapatite.
- Calcium homeostasis is crucially maintained through interactions between skeletal system, gut, and kidneys.
Joint Types and Movement
- Ellipsoidal Joints: Allow biaxial movement (e.g., wrist joints).
- Condylar Joints: Freer movement, where concave and convex surfaces meet (e.g., sternoclavicular joint).
- Ball-and-Socket Joints: Multiaxial joints allowing the greatest range of movement (e.g., hip and shoulder joints).
