This video provides an introduction to the cell types of the nervous system. Explore the world of neural cells, the building blocks of our nervous system. Uncover the roles and functions of neurons and glia, and how they work together to regulate our body's functions. Discover the structure of the nervous system, divided into the central and ...
A nerve cell (neuron) consists of a large cell body and nerve fibers—1 elongated extension (axon) for sending impulses and usually many branches (dendrites) for receiving impulses. The impulses from the axon cross a synapse (the junction between 2 nerve cells) to the dendrite of another cell. Each large axon is surrounded by oligodendrocytes ...
11 de abr. de 2024 · Stem Cell Therapy: A promising treatment that uses stem cells, particularly mesenchymal stem cells, to regenerate damaged nerve cells and improve nerve function in various types of neuropathy. Exosome Therapy: An innovative therapy that uses small vesicle cell release to promote nerve regeneration and reduce inflammation in neuropathic conditions.
Neurons contain organelles common to many other cells, such as a nucleus and mitochondria. They also have more specialized structures, including dendrites and axons. Not shown: the axon hillock is located between the cell body and the start of the axon. Image credit: OpenStax Biology.
Nerve cells (neurons) manipulate information. Doing so involves changes in the bioelectrical or biochemical properties of the cell, and these changes require a vast expenditure of energy for each cell. The nervous system, compared with other organs, is the greatest consumer of oxygen and glucose.
A neuron or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses. It is the main compo...
The neuron is one of two basic types of cells in the nervous system, the other type being the glial cell. Figure 11.3.1 11.3. 1: Interneurons of Adult Visual Cortex. Neurons, also called nerve cells, are electrically excitable cells that are the main functional units of the nervous system.
