Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

4.9K
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,...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

4.3K
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...

The Hyoid Bone01:12

The Hyoid Bone

4.7K
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...

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

787
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Arteries of the Head and Neck01:26

Arteries of the Head and Neck

3.0K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Tooth Anatomy

2.0K
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...

Area of Science:

  • Orthopedic Surgery
  • Anatomy
  • Biomechanics

Background:

  • The coronoid process is a key bony structure of the ulna.
  • It plays a significant role in maintaining elbow joint stability.
  • Understanding its anatomy is vital for treating elbow injuries.

Purpose of the Study:

  • To review the function of the coronoid process in elbow stability.
  • To highlight various surgical approaches for accessing the coronoid.
  • To provide detailed descriptions of medial surgical approaches.

Main Methods:

  • Literature review of existing studies on coronoid anatomy and surgery.
  • Analysis of different surgical techniques, focusing on medial approaches.
  • Description of anatomical landmarks and exposure provided by each approach.

Main Results:

  • The coronoid process contributes significantly to elbow stability through buttressing and resisting posterior-lateral rotatory instability.
  • Medial surgical approaches offer varying degrees of access to different parts of the coronoid.
  • Specific medial approaches are detailed, including their advantages and indications.

Conclusions:

  • The choice of surgical approach to the coronoid should be tailored to the specific pathology and the required anatomical exposure.
  • Medial approaches are valuable for addressing coronoid fractures and other pathologies requiring direct visualization and fixation.
  • A thorough understanding of the coronoid's anatomy and surgical accessibility is essential for successful treatment of elbow instability.
