Spinal Cord: Cross-sectional Anatomy

2.2K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Regional Terms01:12

Regional Terms

10.1K
Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

Body Planes

16.6K
Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

Overview of Anatomy and Physiology

21.1K
Human anatomy is the scientific study of the body's structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word "anatomy" comes from a Greek root that means "to cut apart." Human anatomy was first studied by observing the body's exterior and the wounds of soldiers and other injuries. Later, physicians were allowed to...

Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

4.5K
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.

Anatomy of the Brain: Major Regions

5.5K
The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...

Area of Science:

  • Radiology
  • Neuroanatomy
  • Medical Education

Background:

  • Computed tomography (CT) is crucial for diagnosing brain pathologies.
  • Accurate interpretation relies on a strong understanding of neuroanatomy.
  • Identifying anatomical variations and pathologies on CT requires specialized knowledge.

Purpose of the Study:

  • To provide a pictorial quiz for identifying normal and abnormal brain anatomy on CT.
  • To emphasize key areas such as the pons, ventricular system, and basal cisterns.
  • To improve the interpretation of intracranial hemorrhages and masses.

Main Methods:

  • A quiz format presenting anatomical structures and pathologies at specific CT levels.
  • Focus on identifying changes from normal anatomy and variations in pathology.
  • Inclusion of differential diagnoses and clinical pearls.

Main Results:

  • The quiz assesses identification of the pons, ventricular system, and basal cisterns.
  • Emphasis on recognizing sub-arachnoid and epidural hemorrhages.
  • Covers masses around the pons, midbrain, cerebellum, and signs of increased intracranial pressure.

Conclusions:

  • This series aims to enhance understanding of sectional brain anatomy for CT interpretation.
  • It serves as a learning tool for radiologists and clinicians.
  • Provides guidance for clinical practice and further learning in neuroimaging.
