Central Nervous System Research Paper

The Central Nervous System (CNS)

The CNS is responsible for coordinating and controlling the activities of our body such us control of the muscles and the mental activity. The main organs of the CNS is the brain, spinal cord, and nerves. These organs mostly consist of Nervous Tissues.

Nervous Tissues
Nervous tissues are made up of two main types of cells: nerve cells/neurons and neuroglia. The main functions of nervous tissues are to react to stimuli and generate impulses to various organs in the body.

Nerve cells and Neuroglia
Neuroglia do not transmit nerve impulses themselves, but they are important to the neurons because they are responsible for supporting them by providing the nutrition they need. They are also responsible for the protection of neurons, destroying pathogens, and removing dead neurons. Neuroglia are found surrounding neurons.
They generate and send nerve impulses to other nerve cells. This information is passed onto other cells through the synapses. Synapses are gaps or junctions between two nerve cells. At the synapse, one nerve cell will send a signal to another.
