Parts of the Brain and their Functions
When you think of a brain, what comes to mind is probably a wrinkly blob. The human brain has a soft, shiny, grayish-white mushroom like structure, but there is a lot more to the brain than what it looks like. The human brain is truly one amazing organ that performs numerous of tasks. It controls our heart rate, body temperature, blood pressure and our breathing. It receives a ton of information about the world around us from our senses (hearing, seeing, smelling, tasting and feeling). It handles our physical movements when walking, talking, standing or sitting. It also lets us think, dream and feel emotions. All of this is controlled by an organ that is about the size of a cantaloupe.
The brain is the most complex organ in our bodies, without the brain we wouldn’t be able to do most of the things that we do now. Being that the brain is so complex with many different parts to it, we are able to separate it by the different structures and their functions. There are three main parts to the brain, the hindbrain, the limbic system and the neo-cortex, and aside from that you have the association areas of the cortex. All of these parts have different structures within them that help make up the functioning of the brain.
The hindbrain is located at the rear of the brain. The structures that are within the hindbrain include the spinal cord, the medulla oblongata, the pons and the cerebellum. The spinal cord is connected to the brain and is about the size of a human’s finger. It goes down the middle of our backs and is protected by the vertebral column. The spinal cord is like a highway of information for the body. It carries the information up to the brain and instructions back down. Specifically, there are nerves that are located in the spinal cord that are grouped together in different bundles called ascending and descending spinal tracts. The ascending tracts carry sensory information from the body up to the brain. This...
