Direct Cannula Implantation in the Cisterna Magna of Pigs
Published on: June 9, 2021
Summary
A rare tubercle in the anterior foramen magnum was found in 1.3% of adult human skulls. Radiographic analysis explored its cause and morphology, suggesting a link to occipitovertebral region injuries.
Area of Science:
- Anatomy
- Radiology
- Forensic Anthropology
Background:
- The anterior margin of the foramen magnum is a critical anatomical region.
- Variations in this area can have clinical implications.
- Understanding anatomical landmarks is crucial for diagnosing and treating injuries.
Purpose of the Study:
- To investigate the incidence and characteristics of a tubercle at the anterior margin of the foramen magnum.
- To clarify the etiology and internal morphology of this specific anatomical variant.
- To explore potential associations between this tubercle and traumatic medullar lesions.
Main Methods:
- Examination of 382 adult human skulls (Caucasian).
- Radiographic analysis to determine internal morphology and potential causes.
- Statistical analysis to determine incidence rates.
Main Results:
- The tubercle was present in 1.3% of the studied skulls.
- Radiographic findings provided insights into its internal structure.
- The anatomical position suggests a potential relationship with the occipitovertebral junction.
Conclusions:
- The tubercle of the anterior foramen magnum margin is a rare anatomical finding.
- Its morphology and position warrant further investigation regarding potential clinical significance.
- This anatomical variant may be relevant in cases of traumatic medullar lesions in the occipitovertebral region.

01:30General Structure of a Vertebra
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous column.
01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:26Bone Markings
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:28Articulations of the Vertebral Column
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
01:15Spinal Cord: Gross Anatomy
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...
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,...
