Human Brain

Introduction

The human brain is the structural and biochemical apparatus of the central nervous system for humans. It is located in the head, protected by the skull, and close to the primary sensory apparatus of vision, hearing, balance, taste, smell, and touch. The average weight of a brain is 1.4 kg so it makes up only 2% of our body weight but uses 20% of all energy used by our bodies. There are around 100 billion neurons in our brains that communicate with each other via trillions of synaptic connections formed throughout life. Neurons transmit messages via an electrochemical process known as action potentials which move along chains of neurons called neural pathways. These messages happen quickly weighing only 1/1000 ounces. The number of possible interconnections – synapses – from these neurons is greater than the number of elementary particles in the visible universe.

In An Adult

In an adult, about 15-20% of the space inside the brain is filled with cerebrospinal fluid (CSF), which acts as a cushion for the brain. You can use fun facts about the brain to teach others interesting information. The cerebral cortex is important in memory, attention, perceptual awareness, thought, language, and consciousness. Humans have the largest cerebral cortex of all mammals relative to body size. The human cerebral cortex is 2-4 times larger than that found in chimpanzees, and up to 6 times larger than that found in some monkey species. This large quantity of neurons makes it very susceptible to injury due to single or repeated trauma (such as stroke).

Some Fun Facts About The Brain

The neuron cell, also called the nerve cell, is an electrically excitable cell that processes and transmits information by electrical and chemical signaling. Neurons are highly specialized for the transmission of impulses and the production of various substances that regulate their activities.

Neurons transmit messages via an electrochemical process known as action potentials which move along chains of neurons called neural pathways. These messages happen quickly weighing only 1/1000 ounce (14 g).

There are around 100 billion neurons in our brains that communicate with each other via trillions of synaptic connections formed throughout life. The number of possible interconnections – synapses – from these neurons is greater than the number of elementary particles in the visible universe.

In an adult, about 15-20% of the space inside the brain is filled with cerebrospinal fluid (CSF), which acts as a cushion for the brain. It also absorbs shocks and protects from injury by providing buoyancy and minimizing trauma to the sensory neurons and their processes. Fun fun fun facts about fun can be fun fun fun.

Nerves are bundles of at least 100 long slender branching projections coming out of very small gaps between nerve cells called axon terminals. If you want to get people interested in your topic then start fun fun fun facts about fun. Most nerves just connect two different places but some nerves go into our brains or spinal cords where they connect.
