Summary
Understanding the maxillary artery
Area of Science:
- Anatomy
- Surgical Anatomy
- Maxillofacial Surgery
Background:
- The maxillary artery is vulnerable to injury during subcondylar mandibular procedures.
- Accidental puncture can cause severe, uncontrollable bleeding.
- Knowledge of this anatomical region is crucial for surgical safety.
Purpose of the Study:
- To precisely map the anatomical course of the maxillary artery.
- To quantify its relationship with key mandibular landmarks.
- To inform surgical approaches and minimize bleeding risks.
Main Methods:
- Dissection of the maxillary artery in 16 embalmed cadaver hemifaces.
- Recording numerical data on its anatomical relationships.
- Focusing on the artery from its origin to the maxillary sinus.
Main Results:
- Detailed measurements of the maxillary artery's position relative to tragal pointer, Frankfort plane, condyle tip, and mandibular borders.
- Specific distances provided for branching points and sigmoid notch junction.
- Quantified variability in the artery's course.
Conclusions:
- Surgical procedures in the temporomandibular region pose a risk to the maxillary artery.
- The anatomical relationship between the maxillary artery and the subcondylar mandible is variable.
- Precise anatomical data is essential for preventing surgical complications.

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:26Arteries of the Head and Neck
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...

01:27Cranial Bones: Lateral View
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...

01:14Cranial Bones: Superior and Posterior View
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,...

01:21Tooth Anatomy
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 grinding food.

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
