Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

2.5K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Anatomy of the Brain: Ventricles

6.1K
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 Arch of Aorta01:10

The Arch of Aorta

1.2K
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...

Veins of Head and Neck01:19

Veins of Head and Neck

3.8K
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...

Cerebrospinal Fluid01:21

Cerebrospinal Fluid

3.9K
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:

  • Neurosurgery
  • Neurology
  • Developmental Neuroscience

Background:

  • Interhemispheric arachnoid cysts are rare congenital malformations.
  • Often associated with midline neurodevelopmental abnormalities like corpus callosum agenesis.

Observation:

  • A 27-year-old female presented with worsening headache, memory deficits, and radiological cyst progression.
  • The interhemispheric arachnoid cyst showed significant radiological enlargement.

Findings:

  • Craniotomy for cyst fenestration into the interhemispheric cistern and lateral ventricle was performed.
  • Postoperative recovery was uneventful, with marked clinical improvement and cyst size reduction.

Implications:

  • Microsurgical fenestration is an effective treatment for symptomatic interhemispheric arachnoid cysts.
  • This approach can alleviate progressive neurological deficits and reduce cyst volume.
