Nervous Tissue Characteristics

In this article we will discuss about the nervous tissue characteristics

Nervous Tissue Characteristics

• Nervous tissue is highly specialised to transmitting the stimulus very rapidly from one place to another within the body
• Nerve tissue is the main tissue of our nervous system
• Nervous tissue found in brain, spinal cord and nerves throughout body
• Nervous tissue consists of two cells: nerve cells (neuron) and neuroglia
• Nervous cells are basic cellular unit of nervous system
• Nerve cells live and function optimally for lifetime
• Neurons lose their ability to divide and cannot be replaced if destroyed
• Nerve cells vary in shape and size, all neurons contain three parts- cell body, dendrites and axon
• Cell body which contains the nucleus, cytoplasm and cell organelles
• Dendrite is a highly branched cytoplasmic extension, responsible for receiving impulses from outside & pass to the cyton
• Axons are long stem-like projections emerging out of the cell, it conducts nerve impulse away from cell body
• Neuroglia are non-conducting cells that protect and nurture as well as support cells of nervous tissue.
• Nervous tissue requires continuous and abundant supplies of oxygen and nutrients
• Nervous tissue transmits nerve impulses across body and coordinate, regulate, integrate body functions
