Joints Chapter 8
What is a joint? Defined as the site where two or more bones meet. Also called an “articulation” Joints allow our skeleton mobility and they hold our skeleton together
Classification of Joints Functional classification Synarthroses Amphiarthroses Diarthroses
Classification of Joints Structural classification Fibrous joints Cartilaginous joints Synovial joints
FIBROUS JOINTS General Characteristics Bones are joined by fibrous tissue No joint cavity is present Most are immovable but some are slightly moveable
TYPES OF FIBROUS JOINTS Sutures (synostoses) Syndesmoses Gomphoses
FIBROUS JOINTS Sutures Synostoses =fused sutures
FIBROUS JOINTS Syndesmoses
FIBROUS JOINTS Gomphoses
CARTILAGINOUS JOINTS General Characteristics Articulating surfaces are united by cartilage No joint cavity Can be synarthrotic or amphiarthrotic
TYPES OF CARTILAGINOUS JOINTS Synchondroses Symphyses
SYNOVIAL JOINTS General Characteristics Articular bones are separated by a fluid-filled cavity Joints of limbs Diarthrotic
Movements of synovial joints Axis of motion Nonaxial Uniaxial Biaxial Multiaxial
Types of Synovial Joints
Specific Joints & Injuries Knee (Stifle) 3 C’s—collateral ligaments, cruciate ligaments, cartilages (menisci) Shoulder (Glenohumeral) Rotator cuff—four tendons encircle & blend with articular capsule
Specific Joints & Injuries Hip (Coxal) Deep socket & strong ligaments, very stable Temporomandibular (TMJ) Dislocation easy—shallow socket
Joint Disorders Sprains Dislocations Luxation Subluxation Bursitis “Housemaid’s Knee” “Student’s elbow” Tendonitis Arthritis Osteoarthritis Rheumatoid arthritis Synovitis
