Neurulation01:30

Neurulation

47.3K
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...

The Retinoblastoma Gene

4.9K
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,...

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.

Spinal Nerves: Plexus II01:21

Spinal Nerves: Plexus II

3.2K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Cranial Nerves: Types Part II

5.9K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
Facial Nerve (Cranial Nerve VII)

Summary
This summary is machine-generated.

Neurofibromatosis type 2 (NF2) is a genetic disorder causing tumors on nerves. Mutations in the NF2 gene lead to schwannomas and meningiomas, impacting life expectancy.

Area of Science:

  • Genetics
  • Oncology
  • Neurology

Background:

  • Neurofibromatosis type 2 (NF2) is an autosomal dominant disorder.
  • Caused by mutations in the NF2 tumor suppressor gene on chromosome 22.
  • Affects approximately 1 in 33,000 people, with de novo mutations occurring in over a third of cases.

Purpose of the Study:

  • To provide a comprehensive overview of Neurofibromatosis type 2.
  • To detail the genetic basis, clinical manifestations, and prognosis associated with NF2.
  • To highlight the key tumor types and diagnostic features of NF2.

Main Methods:

  • Review of existing literature on NF2.
  • Analysis of genetic mutations and their correlation with clinical outcomes.
  • Compilation of data on tumor development and prevalence.

Main Results:

  • NF2 significantly impacts life expectancy, with truncating mutations conferring the worst prognosis.
  • The majority of individuals develop bilateral vestibular schwannomas, alongside other cranial, spinal, and peripheral nerve schwannomas.
  • Other common tumors include cranial and spinal meningiomas and intraspinal ependymomas.

Conclusions:

  • NF2 is a complex genetic disorder with a high predisposition to tumor formation.
  • Early identification and understanding of NF2 are crucial for managing patient prognosis and life expectancy.
  • Further research into NF2 pathogenesis and treatment strategies is warranted.
