ulna & radius

ulna :

  • olecranon : top of ulna 

  • olecranon process : left side of olecranon

  • trochlear (semilunar) notch : middle of olecranon 

  • coronoid process : right under olecranon 

  • radial notch of ulna : little dip in olecranon 

  • ulna tuberosity : under coronoid process 

  • styloid process of ulna : bottom piece of ulna 

radius : 

  • head : top of radius

  • radial tuberosity : circle shape on side of radius 

  • styloid process of radius : bottom of radius (way larger than ulna)
