The Hyoid Bone01:12

The Hyoid Bone

6.7K
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...

Muscles of the Anterior Neck01:26

Muscles of the Anterior Neck

6.1K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Tongue01:01

Tongue

4.2K
The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

6.8K
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 View01:14

Cranial Bones: Superior and Posterior View

7.6K
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,...

Tooth Anatomy01:21

Tooth Anatomy

2.7K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Summary
This summary is machine-generated.

The hyoid bone (HB) position changes with vertical jaw dysplasia, particularly in deep bite cases. This finding suggests the HB may aid in diagnosing this skeletal pattern.

Area of Science:

  • Anatomy
  • Orthodontics
  • Anthropology

Background:

  • The hyoid bone (HB) is a unique bone crucial for vital functions.
  • Its position relative to the craniofacial skeleton is of clinical interest.
  • Vertical jaw dysplasia involves abnormal facial growth patterns.

Purpose of the Study:

  • To investigate changes in hyoid bone position in individuals with vertical jaw dysplasia.
  • To test the hypothesis that hyoid bone position remains unchanged in this condition.

Main Methods:

  • Utilized eleven factors to determine hyoid bone position.
  • Employed two-way analysis of variance (ANOVA) to analyze positional variability.
  • Assessed associations with facial type, gender, and their interactions.

Main Results:

  • Hyoid bone position correlates with vertical skeletal patterns, showing distinct relationships in deep bite and open bite.
  • Significant sexual dimorphism in hyoid bone position was observed.
  • Specific measurements indicated differences in hyoid bone positioning between genders and facial types.

Conclusions:

  • A clear relationship exists between hyoid bone position and vertical skeletal patterns, especially deep bite.
  • The hyoid bone's position is significantly associated with vertical jaw dysplasia.
  • The hyoid bone may be a valuable indicator in the differential diagnosis of vertical jaw dysplasia.
