Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

2.9K
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,...

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

2.8K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Overview of the Skull01:08

Overview of the Skull

5.4K
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...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

2.7K
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...

Cranial Nerves: Overview and Anatomy

2.5K
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...

Sutures of the Skull01:22

Sutures of the Skull

7.7K
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...

Area of Science:

  • Anatomy
  • Medical Imaging
  • Emergency Medicine

Background:

  • Controlling craniofacial bleeding with pressure on arteries is vital in first aid.
  • Precise anatomical locations for arterial pressure points are not well-defined.

Purpose of the Study:

  • To precisely identify and map optimal pressure points on key craniofacial arteries.
  • To provide anatomical guidance for effective hemorrhage control in emergencies.

Main Methods:

  • Retrospective analysis of 201 adult CTA scans, 3D postprocessed.
  • Mapping of facial, superficial temporal, occipital, transverse facial, and posterior auricular arteries.
  • Utilized coordinate systems anchored at specific facial and occipital landmarks to determine pressure point locations.

Main Results:

  • Identified ten bilateral pressure points, consistently accessible for compression.
  • Facial and occipital artery points are further from landmarks than superficial temporal, transverse facial, and posterior auricular arteries.
  • Over 95% of superficial temporal, transverse facial, and posterior auricular points are addressable with a single gesture.

Conclusions:

  • An atlas of craniofacial pressure points provides practical anatomical guidance for first responders.
  • Enhances hemorrhage control training programs, with potential for simulation and augmented reality applications.
