Figure 35.3.1 35.3. 1: Glial cells: Glial cells support neurons and maintain their environment. Glial cells of the (a) central nervous system include oligodendrocytes, astrocytes, ependymal cells, and microglial cells. Oligodendrocytes form the myelin sheath around axons. Astrocytes provide nutrients to neurons, maintain their extracellular.

neuroglia, any of several types of cell that function primarily to support neurons.The term neuroglia means "nerve glue." In 1907 Italian biologist Emilio Lugaro suggested that neuroglial cells exchange substances with the extracellular fluid and in this way exert control on the neuronal environment.It has since been shown that glucose, amino acids, and ions—all of which influence.

Neuroglia cells are different from nerve cells in that they do not participate directly in synaptic interactions Students can also label a nerve cell and color neuroglia cells using paper handouts. I have also had students model neurons with clay and chalk markers.
Neuroglial Cells

Nervous Tissue Mediates Perception and Response Anatomy and Physiology I
astrocyte: a neuroglial cell, in the shape of a star, in the brain. Neurogila or glial cells, are non-neuronal cells that maintain homeostasis, form myelin, and provide support and protection for neurons in the central (CNS) and peripheral nervous systems (PNS). It was long believed that neuroglia did not play any role in neuro-transmission.

Color The Neuron And Neuroglial Cells
Neuroglia, also called glia or glial cells, are non-neuronal cells of the nervous system. They compose a rich support system that is essential to the operation of nervous tissue and the nervous system. Unlike neurons, glial cells do not have axons, dendrites, or conduct nerve impulses.Neuroglia are typically smaller than neurons and are about three times more numerous in the nervous system.
Histology of the Peripheral Nerves and Light Microscopy NYSORA
Like other cells, each neuron has a cell body (or soma) that contains a nucleus, smooth and rough endoplasmic reticulum, Golgi apparatus, mitochondria, and other cellular components. Neurons also contain unique structures, illustrated in Figure 35.3 for receiving and sending the electrical signals that make neuronal communication possible.

1.1. The Birth of the Concept of Homoeostatic Neuroglia. The complexity of the human brain is remarkable: a population of more than 200 billion (i.e. 2 × 10 11) neural cells (neurones and neuroglia) is packed within a limited volume (average human brain occupies 1200-1400 cm 3).These neural cells form complex networks, connected through 15-20 trillions of chemical and electrical synapses.

Like the heart, lungs, and stomach, the nervous system is made up of specialized cells. These include nerve cells (or neurons) and glial cells (or glia ). Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances.
Anatomy of the Nervous System Microbiology
Glial Cells. Nervous tissue is composed of two types of cells, neurons and glial cells. Neurons are the primary type of cell that most anyone associates with the nervous system. They are responsible for the computation and communication that the nervous system provides. They are electrically active and release chemical signals to target cells.
