Introduction:
The relationship and connection between heart and brain.
There is more information going from the heart to the brain than the other way around,
and this information influences region´s in the brain that affect decision making, creativity and especially emotions.
The general idea is that the body is a downward system, but 85-90% of all neural fibres
carry information from the body to the brain, and a major part of this information
comes from the heart via the nervus vagus.
Differences between brain and heart:
Everything we think is thought in the brain. So, the 'mind' is just our everyday way of saying the 'brain'. Sometimes when we want to talk about feelings, which are a very special kind of thinking, we talk about the 'heart'.
Of course the heart is really only a muscle for pumping blood through the body, but the ancients thought that it was also tied up in some way with our feelings. Since they did not understand physiology, the ancients simply decided that thoughts came from the mind and the heart.
To some, the soul is also an imaginary part of our bodies. Certainly, this is true when we talk of an artist having 'soul'. But, in many religions the soul is also a spirit that forms part of a person and will inhabit an afterlife when the body has died.
The soul is our "higher self", our essence. It is immaterial and feeds off spiritual nourishment. It is where we feel pleasure and where we are, our life almost.
The mind is where we calculate how to receive pleasure, where we make decisions between what is right and wrong and how we live out lives. It is our "self", our consience.
The heart is an organ, it keeps us alive and so is essential to us. It is also the organ that - mythically - governs our feelings. This is in fact false, because we do it with our brain, but there is no denying the fact that it is an important symbological tradition.
Heart is the organ in your chest that sends the blood around your body. Mind is the part of a persons brain that makes it possible for a person to think, feel emotions and understand things. Brain is the organ inside the head that controls thought, memory, feelings and activity. Soul is the spiritual part of a person which some idiots believe continues to exist in some form after their body has died, or the part of a person which is not physical and experiences deep feelings and emotions.
And the simple fact is that the brain is the engine, while the car is the physical body of the human being where the mind is the driver of this car of life and hearts is steering to keep safe your car.
Similarities between brain and heart:
The human heart has a mass of between 250 and 350 grams and is about the size of a fist. It is located anterior to the vertebral column and posterior to the sternum.
It is enclosed in a double-walled sac called the pericardium. The superficial part of this sac is called the fibrous pericardium. This sac protects the heart, anchors its surrounding structures, and prevents overfilling of the heart with blood.
The outer wall of the human heart is composed of three layers. The outer layer is called the epicardium, or visceral pericardium since it is also the inner wall of the pericardium. The middle layer is called the myocardium and is composed of cardiac muscle which contracts. The inner layer is called the endocardium and is in contact with the blood that the heart pumps. Also, it merges with the inner lining endothelium of blood vessels and covers heart valves.
The human heart has four chambers, two superior atria and two inferior ventricles. The atria are the receiving chambers and the ventricles are the discharging chambers. The pathway of blood through the human heart consists of a pulmonary circuit and a systemic circuit. Deoxygenated blood flows through the heart in one direction, entering through the superior vena cava into the right atrium and is pumped through the tricuspid valve into the right ventricle before being pumped out through the pulmonary valve to the pulmonary arteries into the lungs. It returns from the lungs through the pulmonary veins to the left atrium where it is pumped through the mitral valve into the left ventricle before leaving through the aortic valve to the aorta.
The human brain has the same general structure as the brains of other mammals, but is larger than expected on the basis of body size among other primates. Estimates for the number of neurons (nerve cells) in the human brain range from 80 to 120 billion. Most of the expansion comes from the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The portion of the cerebral cortex devoted to vision is also greatly enlarged in human beings, and several cortical areas play specific roles in language, a skill that is unique to humans.
Despite being protected by the thick bones of the skull, suspended in cerebrospinal fluid, and isolated from the bloodstream by the blood-brain barrier, the human brain is susceptible to many types of damage and disease. The most common forms of physical damage are closed head injuries such as a blow to the head, a stroke, or poisoning by a variety of chemicals that can act as neurotoxins. Infection of the brain, though serious, is rare due to the biological barriers which protect it. The human brain is also susceptible to degenerative disorders, such as Parkinson"s disease, multiple sclerosis, and Alzheimer"s disease. A number of psychiatric conditions, such as schizophrenia and depression, are thought to be associated with brain dysfunctions, although the nature of such brain anomalies is not well understood.
The adult human brain weighs on average about 3 lb (1.5 kg) with a size (volume) of around 1130 cubic centimetres (cm3) in women and 1260 cm3 in men, although there is substantial individual variation. Neanderthals, an extinct subspecies of modern humans, had larger brains at adulthood than present-day humans. Men with the same body height and body surface area as women have on average 100g heavier brains, although these differences do not correlate in any simple way with gray matter neuron counts or with overall measures of cognitive performance. The brain is very soft, having a consistency similar to softgelatin or soft tofu. Despite being referred to as "grey matter", the live cortex is pinkish-beige in color and slightly off-white in the interior. At the age of 20, a man has around 1.76 km and a woman about 1.49 km of myelinated axons in their brains.
And the main fact is that, Heart and brain both are vital organs and both are protected by tough bones, heart is protected by ribs and brain is protected by skull, both have there own system, brain control nervous and heart control circulatory. We can not live without these organs.
