It is worth noting that the styloid may be enlarged ( > 30 millimeters in length ) in 4 % of the population and only a small minority ( ~ 4 % ) of people with enlarged styloids have symptoms.
42.
The medial part of the "'lower border "'is thin and sharp; its lateral part splits to enclose the root of the styloid process, and is therefore named the " vaginal process ".
43.
The dorsal aspect of its base presents on its radial side a pyramidal eminence, the styloid process, which extends upward behind the capitate; immediately distal to this is a rough surface for the attachment of the extensor carpi radialis brevis muscle.
44.
The ulnar styloid process ( a projection on the ulna, one of the bones of the forearm, where it meets the wrist ) is not as hooked as in other lorisids, according to Schwartz, which Groves suggests may indicate that the wrist is more mobile.
45.
"The area is slightly behind that big bone, that kind of knob ( ulna styloid ) that sticks out on the side of your wrist, " said Abbott, whose other star Boston client, Kyle McLaren, remains a holdout, awaiting a trade.
46.
It rotates around the ulna and the far end ( where it joins to the bones of the hand ), known as the styloid process of the radius, is the distance from the ulna ( center of the circle ) to the edge of the radius ( the circle ).
47.
The "'dorsal border "'( " margo dorsalis; posterior border " ) begins above at the back of the neck, and ends below at the posterior part of the base of the styloid process; it separates the posterior from the lateral surface . is indistinct above and below, but well-marked in the middle third of the bone.
48.
The posterior belly may arise partly or entirely from the styloid process, or be connected by a slip to the middle or inferior constrictor; the anterior belly may be double or extra slips from this belly may pass to the jaw or Mylohyoideus or decussate with a similar slip on opposite side; anterior belly may be absent and posterior belly inserted into the middle of the jaw or hyoid bone.
49.
The dorsal border ( " margo dorsalis; posterior border " ) begins above at the apex of the triangular subcutaneous surface at the back part of the olecranon, and ends below at the back of the styloid process; it is well-marked in the upper three-fourths, and gives attachment to an aponeurosis which affords a common origin to the flexor carpi ulnaris, the extensor carpi ulnaris, and the flexor digitorum profundus; its lower fourth is smooth and rounded.
