Question

identify which of the following joints would be functionally diarthrotic. select all that apply.
glenohumeral (shoulder)
pubic symphysis
epiphysial plate
gomphosis (tooth in socket)
patellofemoral/tibiofemoral (knee)
radiocarpal (wrist)
intervertebral
interosseous membrane
acetabulofemoral (hip)
humeroulnar/humeroradial (elbow)
cranial sutures

Explanation:

Diarthrotic joints are freely movable joints. The glenohumeral (shoulder) is a ball - and - socket joint allowing a wide range of motion. The patellofemoral/tibiofemoral (knee) is a modified hinge joint with significant mobility. The radiocarpal (wrist) is a condyloid joint enabling movement. The acetabulofemoral (hip) is a ball - and - socket joint with extensive motion. The humeroulnar/humeroradial (elbow) is a hinge joint allowing flexion and extension.
The pubic symphysis is a cartilaginous joint with limited movement (amphiarthrotic). The epiphysial plate is a growth plate (synchondrosis, synarthrotic). The gomphosis (tooth in socket) is a fibrous joint (synarthrotic). The intervertebral joints have some movement but are not as freely movable as diarthrotic joints (amphiarthrotic). The interosseous membrane is a fibrous joint with very little movement (amphiarthrotic). Cranial sutures are fibrous joints (synarthrotic).

Answer:

Glenohumeral (Shoulder), Patellofemoral/Tibiofemoral (Knee), Radiocarpal (Wrist), Acetabulofemoral (Hip), Humeroulnar/Humeroradial (Elbow)
