The brains is our most important organ in terms of our behavior. Without this important institution, we are unable to function. This is made possible by billions of cells in our brain, which each have their own function. Our nervous system consists of two types of cells, neurons and glia. Each have their own important role in our body. And many people not knowing what they are and what they do.
Neurons
Neurons are cells that receive information and move it to other cells through electrical impulses.
A neuron consists of a nucleus, a membrane (separates the interior of the outer cell), mitochondria (the cell that provides energy), ribosomes (here, the new cell, protein molecules). Most neurons still have the following components: Dendrite, a cell body, an axon and presynaptic terminals.
There are three types of neurons
* Motor Neurons
* Sensor Neurons
* Inter Neurons
Motor neuron impulses lead to their cell body in the spinal cord to muscles and glands, and they receive stimuli from other neurons. The sensor neurons are sensitive to certain stimuli and insensitive to others types of incentives. For example, neurons that are sensitive to touch. The Inter Neurons receive information from neurons and send it on to other neurons.
Glial
Glial cells are also in the nervous system. They release chemicals on to neighboring neurons. Their cells form a layer around the axon (myelin sheath). The glial cells secrete axons from each other, take away waste and promote growth of neurons.
There are also three types of glial cells
* Astrocytes
* Oligodendrocytes
* Blood-brain barrier
Astrocytes remove the waste. They are wound to the presynaptic terminals of different axons. Oligodendrocytes insulate the axons and some myelin building. Blood-brain barrier is an important mechanism that viruses from the brains hold. However, should viruses come through it's forever. The brains are unable to banish it to slow down viruses. The berscherming of blood - brains.
The nervous system consists of neurons and glia. Its main coordinating role in all our actions. The muscles contract, incentives collect our senses and cognitive and emotional processes come from our nervous system. It is the intricate system in our body that can regulate hundreds of activities at once.
