What attaches to styloid process of ulna?

Why does my ulnar styloid process hurt?
Ulnar styloid impaction syndrome involves repetitive friction between an excessively long ulnar styloid and the carpus, resulting in chondromalacia, synovitis, and pain.
What is the styloid process for?
The styloid process gives origin to three muscles, the styloglossus, stylohyoid, and stylopharyngeus. The styloglossus receives innervation from CN XII, attaches to the apex of the tongue, and draws up the sides of the tongue to form a conduit that facilitates swallowing.
What is Eagle’s syndrome?

What is styloid process?
The styloid process is a cylindrical, slender, needle-like projection of varying lengths averaging 2 to 3 cm. The styloid process projects from the inferior part of the petrous temporal bone and offers attachment to the stylohyoid ligament and the stylohyoid, stylopharyngeus, and styloglossus muscles.
What are the styloid process of radius and ulna?
end of the radius, the styloid process, may be felt on the outside of the wrist where it joins the hand. The inside surface of this process presents the U-shaped ulnar notch in which the ulna articulates.
