Hundreds of billions of neuron cells make up the human brain, each of which detects and transmits information to other nerve cells.
The peripheral nervous system encompasses all nerves in our body, except from those in our brain and spinal cord.
It acts as a link between our brain and our limbs, allowing you to communicate with them.
The cell bodies of nerve cells have two types of branches that arise (neurons). The terminals of nerve cells that receive messages from other nerve cells are known as dendrites.
Axons carry incoming signals from the cell body to other cells, such as a neighbouring neuron or muscle cell. Because neurons are interconnected, they can communicate efficiently.
Electrical impulses are sent out when a nerve cell (neuron) is triggered to connect with other cells. The impulse travels to the axon tip of a neuron, causing neurotransmitters, or chemical messengers, to be released.
Neurotransmitters pass through the synapse between nerve cells and link to receptors on the receiving cell. This process repeats itself from neuron to neuron as the impulse goes to its destination – a network of communication that allows you to move, think, feel, and communicate.
