Neural Regulation

34.5K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...

Disorders of the Nervous Tissue

3.0K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...

Summary

Cavum variations are common in neurological brain diseases, with cavum vergae being the most frequent. These variations do not differ significantly between congenital and acquired brain conditions or between children and adults.

Area of Science:

  • Neuroimaging
  • Neurology
  • Radiology

Background:

  • The prevalence of cavum variations in healthy individuals and neurologically diseased patients remains unclear.
  • Understanding cavum variations is crucial for neurological disease assessment.

Purpose of the Study:

  • To determine the frequency and patterns of cavum variations in patients with neurological diseases.
  • To compare the occurrence of cavum variations across different neurological conditions and age groups.

Main Methods:

  • Retrospective review of 217 cranial CT scans from patients aged 6 months and above.
  • Assessment for the presence of cavum septum pellucidum (CSP), cavum vergae (CV), and cavum velum interpositum (CVI).

Main Results:

  • Cavum variations were observed in 59.9% of reviewed CT scans.
  • Cavum vergae (CV) was the most common (39.6%), followed by cavum velum interpositum (CVI) (24.4%), and cavum septum pellucidum (CSP) (23%).
  • No significant difference in cavum variation frequency was found between congenital and acquired brain diseases (P=0.484) or between children and adults (P=0.101).

Conclusions:

  • Cavum variations are prevalent in patients with neurological brain diseases.
  • Congenital brain diseases do not present a higher frequency of cavum variations compared to acquired lesions.
  • Cavum vergae is the most common variation, while CSP is the rarest.
