Nervous Tissue

• Neurons are found in the Central Nervous System and Peripheral Nervous System.
• Neurons consist of neurons and supporting cells called Neuroglia or Glial cells.
• Neurons are the primary type of cells responsible for computation and communication.
• Neurons are electricity active and release chemical signals to target cells.
• Parts of Neurons include Soma, Axon, Synapses, and Dendrites.
• Types of Neurons include Unipolar neuron, Bipolar, Multipolar, and Pseudounipolar.
• Neuroglia play a supporting role and without them neurons will not be able to perform their function.
• Types of Neuroglia include Ependymal cells, Oligodendrocytes, Astrocytes, and Microglia.
• Ependymal cells line ventricular cavities within the brain and are located in the Brain of central and the canal of spinal cord.
• Oligodendrocytes cover up to 50 myelin sheath and are located in white and gray matter.
• Astrocytes exhibit numerous processes that contain glial process and are located in White matter.
• Microglia secrete cytokinesis, synthesize & release trophic factors and are located in Brain & spinal cord.
• Satellite Cells are precursors to skeletal muscle cells and are responsible for regeneration.
• Schwann cells cover 1 myelin sheath and are located at close contact with axons in peripheral nerves.
