Neural Tissue

 The brain, spinal cord, and nerves all include nerve tissue or neural tissue. It is in charge of coordinating and controlling various bodily functions. It promotes muscle contraction, raises environmental awareness, and is involved in emotions, memory, and thinking. The body's reactivity to changing conditions is mostly controlled by neural tissue. Nerve cells, often known as neurons, make up nervous tissue. Neurons are specialized cells that respond to stimuli by sending out signals via axons, which are elongated projections that emerge from the cell body.

Nervous tissue contains two types of cells namely neurons and neuroglia. Neurons are excitable cells that make up the neural system. A cell membrane surrounds neuronal cells. The nucleus of neurons includes genes. Cytoplasm, mitochondria, and other organelles can be found in neurons. Neurons don't divide in any manner. Nerves are actually neuron projections.The rest of the neural system is made up of neuroglial cells that protect and maintain neurons. Neuroglia accounts for more than half of all neural tissue in our bodies. Neuroglia is non-neuronal cells that do not produce electrical impulses in the central nervous system and peripheral nervous system. Neuroglia are found in both invertebrates and vertebrates' nervous systems and are distinguishable from neurons by the absence of axons and the presence of only one kind of process. Furthermore, they do not establish synapses and keep their potential to divide throughout their lives.When a neuron is activated sufficiently, an electrical disturbance is produced that travels quickly through its plasma membrane. When a disturbance reaches the neuron's ends or output zone, it sets off a chain of events that can stimulate or inhibit neighbouring cells.

The nervous tissue is the main tissue component of the two major parts of the nervous tissue: the central nervous system (CNS), which is formed by the spinal cord and brain, and the peripheral nervous system (PNS), which controls and regulates the body's functions and activities. Nervous tissue can be found in peripheral nerves throughout the body as well as central nervous system components such as the spinal cord and brain.
