Joints Flashcards
Tibiofibular joint
Tibia
Fibula
(Knee)
Glenohumeral joint
Glenoid cavity (scapula)
Humerus
shoulder
Temporomandibular joint
Temporal bone
Mandible

connects teh lliums to the sacrum
Metacarpophalangeal joint
Metacarpal
Proximal phalanx
tip of metacarpal joint
Joints are classified:
Structurally
Functionally
Structural joints
Fibrous – no synovial cavity, bones held together by connective tissue
Cartilagenous – no synovial cavity, bones held together by cartilage
Synovial – synovial cavity, bones held together by an articular capsule
Functional Classification: (USED FOR OTHER QUESTIONS)
Synarthrosis – immovable
Amphiarthrosis – slightly movable
Diarthrosis – “freely movable”
Fibrous joints - functional classification
Synarthroses
Amphiarthroses
Cartilagenous joints - functional classification
Synarthroses
Amphiarthroses
Synovial joints - functional classification
Diarthroses
Suture (Fibrous joint)
Bones are connected by a thin layer of connective tissue
Only present between the skull bones
Children = Amphiarthrosis (slightly movable)
Adults = Synarthrosis (immovable)
Syndesmosis (Fibrous Joints)
Bones are connected by connective tissue that is arranged into a ligament
Examples:
Distal tibiofibular joint
Gomphoses (“teeth joints”)
Amphiarthrosis (slightly movable)
Interosseous Membrane (Fibrous Joints)
Bones are connected by a sheet of connective tissue
Present between the radius/ulna and tibia/fibula
Amphiarthrosis (slightly movable)
Synchondrosis (Cartilagenous Joints)
Bones are connected by hyaline cartilage (later ossifies into bone)
Example:
1st sternocostal joint (others are synovial)
Epiphyseal growth plates
Synarthrosis (immovable)
