Neurology – The Basic Anatomy

Neurology – The Basic Anatomy 

The brain is such an important part of the body. The human brain is not only one of the most important organs in the human body; it is also the most complex. The brain is filled with many different cells, neurons and parts. In fact, the brain is split into 4 different parts, also known as lobes. The frontal Lobe, Parietal Lobe, Occipital Lobe, and Temporal Lobe. The human brain also comes with two other parts, called the Cerebellum and the Brain stem. 

Each unique part of the brain has different yet very vital jobs. I thought that I would list them out for you!

Frontal Lobe – Thinking, planning, problem solving, emotions, behaviour, and personality.

Parietal Lobe – Perception, arithmetic, and spelling.

Occipital Lobe – Vision.

Temporal Lobe – Memory, understanding, and language.

(I should also mention that there are two parts of the brain, the motor cortex and the sensory cortex located in between the frontal lobe and the parietal lobe, that I didn’t include because technically they are not defined as actual parts of the brain yet.)

Also here in the image below, I drew the locations of all the parts of the brain, along with their functions. 

Another part of the brain that I mentioned earlier but is none the less important, is the brain stem. The brain stem is an area located at the base of the brain. Its main job is to control involuntary movements such as breathing and heartbeats.

What is a Neuron?

A neuron is specialized cell designed to send information to other parts of the body. Neurons are seen throughout the entire nervous system that transmit information to parts of the body such as muscle, and other nerve cells. Almost all neurons have an axon, cell body, and dendrites. There is a place between two neurons called the ‘synapse’. It’s the part where the neuron sends information to the next neuron. The neuron that received the information is now called the ‘postsynaptic neuron’.

That’s all for now, I hope you enjoyed my second geek out blog post! See you soon!
