Chapter 9 Articulations Lecture Outline Articulations Anatomical classification 1. Fibrous joint 2. Cartilaginous joint 3. Synovial joint Physiological classification 1. Synarthrosis 2. Amphiarthrosis 3. Diarthrosis Synarthroses 1. Synostosis 2. Suture 3. Gomphosis 4. Synchondrosis Amphiarthroses 1. Syndesmosis 2. Symphysis Diarthoses Features: 1. Articular cartilage 2. Synovial cavity 3. Articular capsule Fibrous capsule Synovial membrane 4. Synovial fluid Hyaluronic acid Functions: a. lubrication b. shock absorption c. diffusion 5. Accessory structures A. Meniscus B. Fat pads C. Ligaments D. Tendons E. Bursa F. Synovial tendon sheath Injuries Sprain Bursitis Luxation Subluxation Movements 1. Linear 2. Angular Flexion Extension Hyperextension Abduction Adduction Circumduction 3. Rotational Medial rotation Lateral rotation 4. Special Inversion Eversion Dorsiflexion Plantar flexion Opposition Pronation Supination Protraction Retraction Elevation Depression Ranges of motion 1. Monaxial 2. Biaxial 3. Triaxial 4. Multiaxial Types of synovial joints 1. Gliding/Plane joint 2. Hinge joint 3. Pivot joint 4. Ellipsoidal joint 5. Saddle joint 6. Ball and socket joint Aging Rheumatism Arthritis 1. Osteoarthritis 2. Rheumatoid arthritis Ankylosis 3. Gouty arthritis Amy Warenda Czura, Ph.D.1SCCC BIO130 Chapter 9 HandoutAmy Warenda Czura, Ph.D.2SCCC BIO130 Chapter 9 HandoutDiarthroses = Synovial JointFeatures:1. Articular cartilage: Hyaline cartilage, no perichondrium/periosteum2. Synovial cavity: space between/around opposing bones, has synovial fluid3. Articular capsule: 2 layersouter = dense irregular connective tissue, continuous with periosteuminner = synovial membrane (areolar CT), covers inside surface ofcavity except articular cartilage, secretes synovial fluid4. Synovial fluid: filtrate from blood plasma + hyaluronic acid from fibroblastsFunctions: A. Lubrication B. Shock absorption C. Nutrient distribution: diffusion medium5. Accessory structures A. Meniscus: fibrocartilage pad, subdivides cavity or changes shape of articularsurface, limits range of motion B. Fat pad: adipose, superficial to capsule, protection and space filler C. Accessory ligaments: dense regular connective tissue, either part of capsule,inside joint, or outside capsule; strengthen joint D. Tendons: dense regular connective tissue, attach muscle to bone, add stabilityto joint E. Bursa: synovial fluid filled pocket, reduces friction F. Synovial tendon sheath: tubular bursa around a tendonAmy Warenda Czura, Ph.D.3SCCC BIO130 Chapter 9 HandoutAmy Warenda Czura, Ph.D.4SCCC BIO130 Chapter 9
