Our brains are composed of different distinct functional parts, each responsible for its own unique activity. This cycle is repeated over again until information can be processed and transmitted throughout the brain. When an incoming signal reaches the neuron’s dendrite, it sparks off a chain of biochemical reactions resulting in an electric pulse travelling through its axon – thus allowing neurons to communicate! When the impulse reaches the extremity of the axon, neurotransmitters are released, jumping across a miniature gap known as a synapse and binding to receptors on another neuron. They’re equipped with specific structures called dendrites and axons that enable them to send and receive information respectively. Nerves in the brain hitch a ride on electrical and chemical signals to relay messages. Most importantly however, connecting the two main organs to our spinal cord is an integral component known as the brainstem controlling more fundamental operations like heart rate or breathing for example. At its backend lies the cerebellum which manages physical coordination and balance. The cerebrum, the largest part of our brains and located at the front center of it all, focuses on conscious thinking processes such as movement and sensation. Our brain is a complex organ, comprised of several distinct regions that each serve specific functions. This intricate formation works in tandem to provide us with remarkable mental capability. It consists of over 100 billion nerve cells, also known as neurons, along with multiple trillions of helpful glia. The human brain is an awe-inspiring and mightily influential organ that regulates the whole body’s activities.
