The brilliant brain! here are six facts about the brain that you didn’t know.
The brain enables people to feel, think, and move, as well as automatically regulating most of the activities that go on inside the body.
The largest part of the brain is the cerebrum, the seat of perception and conscious behaviour. the cerebrum has two halves, or hemispheres.
Each halve is covered by a thin layer called the cerebal cortex. despite its thinness, the cortex is the site of all elements of consciousness.
The brain controls the heart and breathing rates, as well as other activities including swallowing =, sneezing and coughing.
Apart from the skull the brain has three connective tissue membranes or meninges or protection. beneath this matter is a wide space that is filled with cerebrospinal fluid.this fluid forms a liquid cushion that reduces the weight of the brain and protects it from knocks ,and jolts.
The walnut like surface of the brain is due to its being folded into sulci (fold) and gyri (bulges). this means that a large surface area of cortex can be squeezed into the limited space within the skull.
