The Brain definition is set to as an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. But the brain is way more complex than that sentence. The brain has four main parts, (Cerebrum, Cerebellum, Limbic System, and Brain Stem), that are made of several different parts.
The Cerebrum, or referred as the cortex is the largest part of the brain, composed of four sections: Frontal Lobe, Parietal Lobe, Occipital Lobe, and Temporal Lobe. In the Cerebrum, you would find higher brain function, like thought and actions. Each Lobe has its own functions. The Frontal Lobe is associated with reasoning, planning, parts of speech, movement, emotions, and problem solving. The Parietal Lobe associates with movement, orientation, recognition, and perception stimuli. The Occipital Lobe is associated with visual processing. The Temporal Lobe associates with perception and recognition of auditory stimuli, memory, and speech. The Cerebrum is also divided into two halves: left and right hemispheres. The two hemispheres look symmetrical, but their functions are slightly different. The right side is associated with creativity, as the left is associated with logic abilities. The Corpus Callosum (a bundle of axons) connects the two hemispheres.
The Cerebellum is known as the “little brain”, as it is very similar to the cerebrum, in that it has two hemispheres and has a highly folded surface or cortex. The structure is associated with regulation and coordination of movement, posture, and balance.
The Limbic System is often referred to as the “emotional brain”, founded buried within the cerebrum. This system includes Thalamus, Hypothalamus, Amygdala, and Hippocampus. The Thalamus is the structure responable for sensory and motor functions. The Hypothalamus is invovled in homeostasis, emotion, thirst, hunger, circadian rhythms, and control of autonomic nervous system. The Amygdala involved in memory, emtion, and fear. The Hippocampus is important for learning and memory for converting short tem memory to more permanent memory.
Under the Limbic System you will find the Brain Stem. This structure is responsible for basic vital life functions, which includes breathing, heartbeat, and blood pressure. The Brain Stem is made of midbrain, pons, and medulla. The Midbrain includes two parts: tectum and tegmentum. The Midbrain functions the vision, hearing, eye movement, and body movement. The Pons is involved in motor control and sensory analysis. The Medulla is bewteen the the pons and spinal cord, and is responsible for maintaining vital body functions, such as breathing and heartrate.
Looking at all the parts and their functions, I also came along some interesting facts. It's important to stay very hydrated, as your brain is 73% water, and only takes 2% dehydration to affect your attention, memory, and other cognitive skills. Something very interesting I found was, "Ninety minutes of sweating can temporarily shrink the brain as much as one year of aging." Just like any other cells, all brain cells are not alike. There are as many as 10,000 specific types of neurons in the brain. To make sure you don't become brain dead, your brain has to go without oxygen for at least 5 minutes before brain damage can occur. Talk about being fast, brain information moves at an impressive 260 miles per hour as a race car top out at 240 miles per hour. There are so many interesting facts about the brain. The Be Brain Fit website was a great tool for fun facts, that are incredible.
Even though this video, describes a few more parts and functions I have learned so far, it is a great way to learn and memorize the brain parts and their functions.
