Nervous Tissue: Glial Cells01:31

Nervous Tissue: Glial Cells

2.9K
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...

Nervous Tissue: Myelin01:25

Nervous Tissue: Myelin

2.5K
The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...

Neurogenesis and Regeneration of Nervous Tissue

761
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...

Neurons: The Axon01:21

Neurons: The Axon

3.4K
Axons are long, cytoplasmic processes of nerve cells capable of propagating electrical impulses known as action potentials. The cytoplasm or axoplasm of an axon contains neurofibrils, neurotubules, small vesicles, lysosomes, mitochondria, and various enzymes, all encased within the axolemma, the plasma membrane of the axon.
The axon attaches to the cell body at a cone-shaped elevation called the axon hillock. The initial part of the axon, closest to the hillock, is known as the initial segment....

Area of Science:

  • Neuroscience
  • Glial Biology
  • Developmental Biology

Background:

  • Neural cells are segregated into distinct central nervous system (CNS) and peripheral nervous system (PNS) domains.
  • Specialized regions called transition zones (TZs) host glial cells from both CNS and PNS, alongside other unique TZ cells.

Purpose of the Study:

  • To review the current understanding of vertebrate transition zone (TZ) cells.
  • To focus on cells located peripherally within spinal cord TZs.
  • To highlight their developmental origin, differentiation, functional importance, and role in disease.

Main Methods:

  • Literature review of current research on vertebrate TZ cells.
  • Comparative analysis of TZ features across species (zebrafish to mice).

Main Results:

  • Detailed discussion of distinct cell types present at vertebrate TZs.
  • Emphasis on cells situated on the peripheral side of spinal cord TZs.
  • Exploration of developmental trajectories and functional significance of these cells.

Conclusions:

  • Vertebrate TZs exhibit common and unique features across species.
  • Understanding TZ cells offers insights into glial biology and potential disease mechanisms.
  • Open questions and challenges in TZ cell research are identified for future investigation.
