Combining The Different Brain Parts

The human brain is an amazing complex and wonderful part of our bodies. We have learned much about its structure and function over the years and have still many aspects to discover. Let’s talk about some important brain parts and what they do.

The brain can be seen as comprised of three main parts. They are referred to as the forebrain, midbrain and hindbrain. The forebrain comprises other parts including the cerebrum, thalamus, and hypothalamus.

The midbrain includes the tectum and tegmentum. And the hindbrain is composed of the cerebellum, pons, and medulla. Within the midbrain, the pons and medulla are often lumped together and referred to as the brainstem.

The cerebrum is the largest part of the human brain. It is known to be associated with higher level brain functions like thought and conscious action. The cerebrum is divided into four sections or lobes. The frontal lobe is associated with reasoning, planning, speech, movement, emotions and problem solving.

The parietal lobe is associated with reasoning, some speech, movement and problem solving. And the occipital lobe is associated with vision and visual processing

The temporal lobe is associated with perception and our ability to recognize auditory stimuli. It also is associated with memory and speech.

The cerebellum is also known as the little brain. It is similar in structure to the cerebrum since it has two hemispheres. This part of the brain is associated with coordinated movement, posture and balance. It plays a pivotal role in our ability to walk, run and generally get around.

The limbic system is referred to as the emotional part of the brain. It is found within the cerebrum. The limbic system contains the thalamus, hypothalamus, amygdale, and hippocampus.

And located underneath the limbic system is the brain stem. This is known to be the most primitive part of the brain. The section controls many of the subconscious and automatic functions in our bodies like berating, heart rate, perspiration, etc. And as indicated earlier, the brainstem is comprised of the midbrain, pons and medulla.

There is much neuroscience have learned about the structure of the brain and what the different parts do. However there is certainly a complex interrelationship between these parts and many of them share functions.

It is interesting to note that in the event a portion of the brain is damaged through injury or disease that other parts of the brain can learn to take over functions where were previously done by other portions. This helps to demonstrate the wonderful way in which the brain can be very flexible and resilient when it needs to be.

In any case there is much we have learned about parts of the brain but much more we still need to learn. It will be an interesting journey.
