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