pectoral girdle

acromial end of the clavicle articulates with the acromial process of scapula

attached to axial skeleton by articulation of the sternal end of the clavicle with the clavicular notch of the manubrium of the sternum

shoulder joint

head of humerus articulates with the glenoid cavity of the scapula

pelvic girdle

articulates with the axial skeleton at the sacroiliac joints

sacroiliac joints

located where the auricular surface of the ossa coxae unite posteriorly with the auricular surface of the sacrum

hip joint

formed by the acetabulum of the os coxa articulating with the head of the femur (ball-and-socket joint)

connected by a strong ligament inside the joint

elbow joint

head of radius articulates with capitulum of humerus

trochlear notch of ulna articulates with trochlea of the humerus

olecranon process of ulna articulates with olecranon fossa of humerus

coronoid process of ulna articulates with coronoid fossa of humerus

radial notch of ulna articulates with head of radius

head of radius articulates with radial fossa of humerus

knee joint

articulation of the medial and lateral condyles of the femur with the medial and lateral condyles of the tibia

patella articulates with the condyles of the femur

head of the fibula is not part of the knee joint but does articulate with the inferior surface of the lateral condyle of the tibia

phalanges

the proximal phalanges (I-V) articulate with the corresponding metacarpals (I-V)

metacarpals

articulate with the carpals proximally (hamate, capitate, trapezoid, and trapezium)

articulate with the corresponding proximal phalanges (I-V)

Temporal mandibular junction

Vertebrocostal Articulation

the head of rib 1 articulates with the superior facet of thoracic vertebra 1

the superior facet of the head of rib 6 articulates with the inferior demarcate of thoracic vertebra 5

the inferior facet of the head of rib 6 articulates with the superior demifacet of thoracic vertebra 6

the tubercle of rib 6 articulates with the transverse process of thoracic vertebra 6

the head of ribs 10,11, and 12 articulate with the facet of vertebrae 10, 11, and 12 respectively
