• Radial fossa

• Capitulum

• Lateral supracondylar ridge

• Trochlea

What is the capitulum?

• A smooth, rounded bony structure located on the distal end of the humerus

• A rough, flat bony structure located on the proximal end of the humerus

• Rotation of the radius head

• Stabilization of the shoulder

Where is the coronoid fossa located?

• On the posterior aspect of the distal humerus

• On the anterior aspect of the distal humerus

• On the lateral aspect of the distal humerus

• On the medial aspect of the distal humerus

What is the function of the olecranon fossa?

• Full flexion of the elbow joint

• Partial flexion of the elbow joint

• Full extension of the elbow joint

• Partial extension of the elbow joint

Which fossa is located on the posterior aspect of the distal humerus?

• Coronoid fossa
