10.1: Neurons and Glial Cells - Biology LibreTexts
2021年9月14日 · Glial cells, or glia, are known to play a supporting role for nervous tissue. Ongoing research pursues an expanded role that glial cells might play in signaling, but neurons are still considered the basis of this function.
Glial Cells: Types and Functions - Verywell Health
2023年3月10日 · Glial cells are a type of cell that provides physical and chemical support to neurons and maintain their environment. Located in the central nervous system and peripheral nervous system, glial cells are sometimes called the "glue" of the nervous system, as well as neuroglia or just glia.
Neurons and Glia: Basic Components of the Nervous System
2022年11月30日 · Neurons are associated with support cells called glia. Neuroscientists have long believed that glia outnumber neurons by 10:1 (or more). However, recent investigations suggest that in some regions of the brains of humans and other primates, that ratio is closer to 1:1. However, the ratio of glia to neuron from region to region varies considerably.

2020年5月13日 · It is a micrograph of human nervous tissue. The neon green structures in the picture are neurons. The neuron is one of two basic types of cells in the nervous system, the other type being the glial cell. Neurons, also called nerve cells, are electrically excitable cells that are the main functional units of the nervous system.
35.1 Neurons and Glial Cells - Biology 2e - OpenStax
Glia guide developing neurons to their destinations, buffer ions and chemicals that would otherwise harm neurons, and provide myelin sheaths around axons. Scientists have recently discovered that they also play a role in responding to nerve activity and modulating communication between nerve cells.

2024年11月23日 · Glia guide developing neurons to their destinations, buffer ions and chemicals that would otherwise harm neurons, and provide myelin sheaths around axons. Scientists have recently discovered that they also play a role in responding to nerve activity and modulating communication between nerve cells.
Neuroglial Cells - Neuroscience - NCBI Bookshelf
Neuroglial cells—usually referred to simply as glial cells or glia—are quite different from nerve cells. The major distinction is that glia do not participate directly in synaptic interactions and electrical signaling, although their supportive functions help define synaptic contacts and maintain the signaling abilities of neurons.
Glial Contributions to Neural Function and Disease - PMC
The nervous system is composed of neurons and glial cells that function together to create complex behaviors. Traditionally, glia have been considered to be merely passive contributors to brain function, resulting in a pronounced neurocentric bias among neuroscientists.

Glia guide developing neurons to their destinations, buffer ions and chemicals that would otherwise harm neurons, and provide myelin sheaths around axons. Scientists have recently discovered that they also play a role in responding to nerve activity and modulating communication between nerve cells.
Neurons and Glia | The Human Brain - Yale University
There are two principal cell types that make up the central nervous system: neurons and glia. Neurons are the primary cells for information processing in the brain. There are different types of neurons and we will discuss them in more detail in the following sections.
