Veins of Head and Neck01:19

Veins of Head and Neck

1.8K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Overview of Systemic Veins

453
Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

The Arch of Aorta01:10

The Arch of Aorta

638
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.
Encircling the heart, the coronary arteries form a ring-like structure before...

Arteries of the Head and Neck01:26

Arteries of the Head and Neck

1.2K
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...

Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

3.9K
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.

Cerebrospinal Fluid01:21

Cerebrospinal Fluid

2.1K
Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain....

Area of Science:

  • Neurology
  • Vascular Medicine
  • Stroke Research

Background:

  • Cerebral venous sinus thrombosis (CVST) is an uncommon cerebrovascular disorder.
  • CVST involves blood clot formation within the dural venous sinuses, crucial for brain blood drainage.
  • It is distinct from cortical venous thrombosis but both fall under cerebral venous thrombosis.

Purpose of the Study:

  • To define cerebral venous sinus thrombosis (CVST) and its anatomical context.
  • To differentiate CVST from cortical venous thrombosis.
  • To provide a comprehensive overview of cerebral venous thrombosis.

Main Methods:

  • Literature review on CVST and related venous pathologies.
  • Anatomical description of dural venous sinuses and cortical veins.
  • Pathophysiological explanation of thrombosis in cerebral veins.

Main Results:

  • CVST is characterized by thrombosis in dural venous sinuses.
  • Cortical venous thrombosis affects superficial cerebral veins.
  • Cerebral venous thrombosis is an umbrella term for both conditions.

Conclusions:

  • Understanding CVST is critical for diagnosing and managing this rare stroke type.
  • Distinguishing between dural sinus and cortical vein thrombosis aids in clinical assessment.
  • Cerebral venous thrombosis requires further research into its specific mechanisms and treatments.
