Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
Disorders of the Nervous Tissue01:28

Disorders of the Nervous Tissue

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.

Neural Regulation01:37

Neural Regulation

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.
The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Area of Science:

  • Genetics
  • Neurology
  • Dermatology

Background:

  • Neurofibromatosis (NF) is a group of genetic disorders.
  • It is inherited in an autosomal dominant pattern.
  • NF is classified into two main subtypes: NF1 and NF2.

Purpose of the Study:

  • To summarize the characteristic features of NF1 and NF2.
  • To outline the commonalities and distinctions between NF1 and NF2.

Main Methods:

  • This is a review article.
  • Information was gathered from existing literature on NF1 and NF2.

Main Results:

  • NF1, or Recklinghausen's disease, affects 1 in 3500 individuals with skin and peripheral nervous system abnormalities.
  • NF2, or central neurofibromatosis, affects less than 1 in 25,000 individuals, often presenting with hearing loss due to vestibular schwannomas and other nervous system tumors.
  • Both types involve tumors of the nervous system.

Conclusions:

  • NF1 and NF2 are distinct genetic disorders with different prevalence and clinical manifestations.
  • Understanding these distinctions is crucial for diagnosis and management.
