Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

2.5K
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...

Cranial Bones: Superior and Posterior View

2.6K
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,...

The Hyoid Bone01:12

The Hyoid Bone

2.7K
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...

Sutures of the Skull01:22

Sutures of the Skull

7.4K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Gross Anatomy of Bone01:17

Gross Anatomy of Bone

6.0K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Overview of the Skull

5.1K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

Summary

This study reports an exceptionally elongated coronoid process (ECP) in a cadaver, measuring over 26 mm. This rare finding has potential clinical implications for temporomandibular joint disorders.

Area of Science:

  • Anatomy
  • Oral and Maxillofacial Surgery
  • Anthropology

Background:

  • Elongated coronoid process (ECP) can cause temporomandibular joint (TMJ) impingement.
  • The exact causes of ECP remain largely unknown.
  • Previous literature lacks comprehensive data on ECP measurements.

Observation:

  • A 63-year-old Caucasian cadaveric specimen was examined.
  • Unilateral ECP was identified during dissection.
  • Measurements revealed an exceptionally long coronoid process on both sides.

Findings:

  • The left coronoid process measured 26.6 mm and the right 26.3 mm.
  • These measurements represent the longest ECP recorded in current scientific literature.
  • The specimen exhibited no other gross anatomical abnormalities.

Implications:

  • This case highlights the potential for extreme ECP variations.
  • Understanding ECP length is crucial for diagnosing and managing TMJ impingement.
  • Further research is needed to explore the etiology and prevalence of ECP.
