Circular proximal end articulates with capitulum of humerus and fits into radial fossa on anterior humerus.

Question 2

Neck

Answer 2

Narrowing immediately distal to head

Question 3

Radial/bicep tuberosity

Answer 3

Distal to neck, anterior medial side in anatomical position; partial insertion of bicep brachii
