Where bones come together. JOINTS Where bones come together. 01 Oct. 2012 Joints.ppt

Classification of Joints Structural Fibrous dense regular/irregular CT Cartilaginous fibrocartilage Synovial Functional Synarthrosis Immovable Amphiarthrosis slightly moveable Diarthrosis very moveable 01 Oct. 2012 Joints.ppt

Classification of Joints Fibrous joints, or sutures Dense regular/irregular CT Completely immovable. Sutures in skull Coronal, Sagittal, Lambdoid, etc. may ossify in adult Sutures in coxal bone ossify in childhood 01 Oct. 2012 Joints.ppt

Classification of Joints Cartilaginous Fibrocartilage or hyaline cartilage Restrict movement, but with some "give" Intervertebral discs Pubic symphysis Costal cartilages hyaline cartilage Epiphyseal plates ossify in late adolescence 01 Oct. 2012 Joints.ppt

Classification of Joints Synovial joints, diarthroses “freely moveable” ?? Wide range of movement 01 Oct. 2012 Joints.ppt

Characteristics of a synovial joint Synovial cavity filled with synovial fluid Articular capsule Outer fibrous capsule Inner synovial membrane Articular cartilage (hyaline) over ends of bones Reinforcing ligaments 01 Oct. 2012 Joints.ppt

Articular capsule Outer fibrous capsule of dense irregular CT Attached to periosteum of articulating bones Portions with parallel fibers = ligaments Inner synovial membrane of loose CT with elastic fibers and adipocytes Secretes synovial fluid (viscous, like egg white) Lubricant Nourishes articular cartilage 01 Oct. 2012 Joints.ppt

Reinforcing ligaments Extracapsular, outside articular capsule Intracapsular, inside articular capsule Covered (surrounded) with synovial membrane e.g. cruciate ligaments of knee 01 Oct. 2012 Joints.ppt

Knee (Tibiofemoral) joint ( a complex synovial joint) Articular capsule with intrinsic and extracapsular ligaments Articular cartilage Extracapsular ligaments Patellar ligament Tibial collateral ligament Fibular collateral ligament 01 Oct. 2012 Joints.ppt

Knee (Tibiofemoral) joint Intracapsular ligaments Anterior cruciate ligament Posterior cruciate ligament Medial & lateral menisci Fibrocartilage pads between femur and tibia Bursae 01 Oct. 2012 Joints.ppt

Knee (Tibiofemoral) joint Bursae of the knee Deep infrapatellar bursa Suprapatellar bursa Prepatellar bursa 01 Oct. 2012 Joints.ppt

Stability and Limits of movement Shape of articulating surfaces and apposition of bones Ligaments Muscle tone and tension Apposition of soft tissues 01 Oct. 2012 Joints.ppt

Types of movement at diarthroses Gliding plane joints Angular saddle, pivot, hinge, ball-and-socket 01 Oct. 2012 Joints.ppt

Directions of angular movement Flexion, extension, hyperextension 01 Oct. 2012 Joints.ppt

Directions of angular movement Abduction, adduction Circumduction 01 Oct. 2012 Joints.ppt

Directions of angular movement Rotation Medial or lateral rotation 01 Oct. 2012 Joints.ppt

Directions of angular movement Pronation, Supination 01 Oct. 2012 Joints.ppt

Directions of angular movement Special movements of a foot plantar flexion dorsiflexion inversion eversion 01 Oct. 2012 Joints.ppt

Homeostatic imbalances of joints Sprain Damaged (torn) cartilage Dislocation Bursitis Tendonitis Osteoarthritis 85% of Americans Erosion of articular cartilage Rheumatoid arthritis >1% of Americans Autoimmune disease Gout, gouty arthritis Crystals of uric acid in joint capsules Ankles, toes 01 Oct. 2012 Joints.ppt
