Joints of the Human Body ASA Bio 2014 Williams
Joints • Where 2 (or more) bones come together • Allows movement • Represent the weakest part of the skeleton
Types of Joints • 3 types of joints • Immovable (Synarthrosis) • Slightly movable (amphiarthrosis) • Fully movable (diarthrosis)
Immovable (Synarthrosis) • No movement between bones • “Fibrous” joints • Sutures
Immovable (Synarthrosis) • No movement between bones • “Fibrous” joints • Sutures • Syndesmosis
Immovable (Synarthrosis) • No movement between bones • “Fibrous” Joints • Sutures • Syndesmosis • Gomphosis
Slightly Movable (Amphiarthrosis) • Very slight movement • “Cartilaginous” joints • Synchondrosis
Slightly Movable (Amphiarthrosis) • Very slight movement • “Cartilaginous” joints • Synchondrosis • Symphysis
Fully Movable (Diarthrosis) • Greatest degree of flexibility • “Synovial” joints • Plane joint (arthroidal)
Fully Movable (Diarthrosis) • Greatest degree of flexibility • “Synovial” joints • Plane joint (arthroidal) • Hinge joint (ginglymus)
Fully Movable (Diarthrosis) • Greatest degree of flexibility • “Synovial” joints • Plane joint (arthroidal) • Hinge joint (ginglymus) • Pivot joint (trochoid)
Fully Movable (Diarthrosis) • Greatest degree of flexibility • “Synovial” joints • Plane joint (arthroidal) • Hinge joint (ginglymus) • Pivot joint (trochoid) • Condyloid (ellipsoid)
Fully Movable (Diarthrosis) • Greatest degree of flexibility • “Synovial” joints • Plane joint (arthroidal) • Hinge joint (ginglymus) • Pivot joint (trochoid) • Condyloid (ellipsoid) • Saddle joint (sellar)
Fully Movable (Diarthrosis) • Greatest degree of flexibility • “Synovial” joints • Plane joint (arthroidal) • Hinge joint (ginglymus) • Pivot joint (trochoid) • Condyloid (ellipsoid) • Saddle joint (sellar) • Ball & socket (spheroidal)
“Synovial” Joints • Articular capsule • Cartilage (hyaline) • Fibrous joint capsule • Synovial membrane • Synovial fluid
Joints • Ligaments: fibrous band that connects two bones • Limits the range of motion at the joint
Joints • Ligaments: fibrous band that connects two bones • Limits the range of motion at the joint • Cartilage: connective tissue that surrounds the ends of bones • Protects bones from wearing down
Joints of the Body • Plane joint • Wrist (inter-carpal), Ankle (inter-tarsal), Patella
Joints of the Body • Hinge joint • Elbow (humerus/ulna), Knee (femur/tibia), Fingers & Toes (inter-phalangeal), Jaw (temporomandibular)
Joints of the Body • Pivot joint • Forearm (elbow/radius/ulna), Neck (atlanto-axial)
Joints of the Body • Condyloid joint • Knuckles (metacarpal-phalangeal), Neck (atlanto-occipital)
Joints of the Body • Saddle joint • Thumb
Joints of the Body • Ball & socket joint • Shoulder (gleno-humeral), Hip (ilio-femoral)
