Nervous Tissue: Glial Cells

3.6K
Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.
Astrocytes are star-shaped glial...

Anorexia Nervosa

182
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Bulimia Nervosa

187
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Neurogenesis and Regeneration of Nervous Tissue

978
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Area of Science:

  • Neuroscience
  • Physiology
  • Psychiatry

Background:

  • Anorexia nervosa (AN) is an eating disorder characterized by intense fear of weight gain and distorted body image, leading to severe weight loss.
  • While physiological anorexia occurs naturally in animals, AN in humans involves complex psychological and neurobiological factors.
  • The neurobiology of feeding extends to the prefrontal cortex (PFC), implicated in food choice and body image perception relevant to AN.

Purpose of the Study:

  • To review recent findings on the role of glial cells in anorexia.
  • To explore the neurobiological underpinnings of anorexia nervosa (AN) using animal models.
  • To identify potential therapeutic avenues by understanding glial cell function in AN.

Main Methods:

  • Literature review of recent studies on anorexia and glial cells.
  • Analysis of neurobiological mechanisms underlying feeding behavior and body image perception.
  • Examination of the role of glial cells in maintaining central nervous system homeostasis.

Main Results:

  • Glial cells, vital for brain homeostasis, may have compromised function in anorexia.
  • The prefrontal cortex (PFC) plays a role in food choice and body image perception relevant to AN.
  • Animal models are crucial for studying the neurobiology of AN due to limited understanding and treatment options.

Conclusions:

  • Glial cell dysfunction is a potential factor in the pathophysiology of anorexia.
  • Further research into the neurobiology of anorexia, particularly glial cell involvement, is warranted.
  • Understanding these mechanisms may lead to the development of more effective treatments for anorexia nervosa.
