  Temporal bone - Wikipedia, the free encyclopedia
On the medial side of the process is a deep groove, the mastoid notch (digastric fossa), for the attachment of the Digastricus; medial to this is a shallow furrow, the occipital groove, which lodges the occipital artery.
situated between the tympanic portion and the mastoid process is the tympanomastoid fissure, for the exit of the auricular branch of the vagus nerve.
The styloid process is developed from the proximal part of the cartilage of the second branchial or hyoid arch by two centers: one for the proximal part, the tympanohyal, appears before birth; the other, comprising the rest of the process, is named the stylohyal, and does not appear until after birth.

At the junction of the anterior root with the zygomatic process is a projection for the attachment of the temporomandibular ligament; and behind the anterior root is an oval depression, forming part of the mandibular fossa, for the reception of the condyle of the mandible.
This process serves for the attachment of the Sternocleidomastoideus, Splenius capitis, and Longissimus capitis.
At the upper and front part of the process they are large and irregular and contain air, but toward the lower part they diminish in size, while those at the apex of the process are frequently quite small and contain marrow; occasionally they are entirely absent, and the mastoid is then solid throughout.

The chorda tympani nerve passes through a canal (canal of Huguier), separated from the anterior edge of the petrotympanic fissure by a thin scale of bone and situated on the lateral side of the auditory tube, in the retiring angle between the squama and the petrous portion of the temporal.
Borders—The superior border of the mastoid portion is broad and serrated, for articulation with the mastoid angle of the parietal.
in length; (10) between the styloid and mastoid processes is the stylomastoid foramen it is the termination of the facial canal, and transmits the facial nerve and stylomastoid artery; (11) situated between the tympanic portion and the mastoid process is the tympanomastoid fissure, for the exit of the auricular branch of the vagus nerve.

The styloid process projects from the medial and back part of the bone; it descends a little lower than the head, and its rounded end affords attachment to the ulnar collateral ligament of the wrist-joint.
The head is separated from the styloid process by a depression for the attachment of the apex of the triangular articular disk, and behind, by a shallow groove for the tendon of the Extensor carpi ulnaris.
Below the coronoid process there is a small area of compact bone from which trabeculæ curve upward to end obliquely to the surface of the semilunar notch which is coated with a thin layer of compact bone.

The styloid process forms a prominent tubercle continuous above with the dorsal border and ending below in a blunt apex at the level of the wrist-joint; it is most evident when the hand is in a position midway between supination and pronation.
The tuberosity of the navicular is distal and medial to the styloid process of the radius, and is most clearly visible when the wrist-joint is extended; the ridge on the greater multangular is about 1 cm.
The base of the metacarpal bone of the thumb, however, is prominent dorsally, distal to the styloid process of the radius; the body of the bone is easily palpable, ending at the head in a flattened prominence, in front of which are the sesamoid bones.

Bone A is the radius and bone B is the ulna.
Image 1 is the cranial view, and because the olecranon (E) curves medially and the styloid process (F) of the ulna is found caudal and lateral to the distal end of the radius, we can identify these bones as the left radius and ulna.
The ulna consists of the olecranon (E) proximally and the styloid process (F) distally.

Eagle's syndrome refers to a head and neck pain syndrome that is felt to be related to elongation of the styloid process or ossification of the stylohyoid ligament which impinges on the glossopharyngeal nerve and classically causes one sided intermittent stabbing, occasionally excrutiating pain in the throat.
If such symptoms are clearly associated with a palpable elongation or protrusion of the styloid process, or ossification of the stylohyoid ligament, and if non-surgical treatments have failed, traditionally excision or fracturing of the styloid process are performed.
