Summary
An elongated styloid process (ESP), though common, can be unusually large. This case details a rare, exceptionally long 88mm ESP discovered during dissection and analyzed histologically.
Area of Science:
- Anatomy
- Histology
- Radiology
Background:
- Elongated styloid process (ESP) occurs in 4% of the population.
- Often incidentally discovered via radiography or CT scans.
- Limited morphometric and histologic data available.
Observation:
- An 88 mm elongated styloid process (ESP) was identified during anatomic dissection.
- The specimen was resected and examined using computed tomography.
- Histological analysis was performed on the resected ESP.
Findings:
- The ESP was composed of bone and cartilage.
- Histology revealed three cartilage types with a beaded appearance.
- Collagenous fibers were observed surrounding the cartilage.
Implications:
- This case presents a significantly large ESP, exceeding typical dimensions.
- Detailed histological findings offer new insights into ESP composition.
- Highlights the value of cadaveric dissection for anatomical research.

01:12The Hyoid Bone
5.9K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

01:27Cranial Bones: Lateral View
7.7K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:09Bones of the Upper Limb: Radius
10.7K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

01:14Cranial Bones: Superior and Posterior View
8.4K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
