The forebrain is responsible for controlling emotions, hunger, sleep, body temperature, reproductive body parts, and functions. The largest part of the human brain is termed the forebrain. The human brain comprises of three parts: It would cause neuron death in the afflicted area. If the brain is not suspended in CSF, its weight will restrict its movement, cutting off blood flow to the bottom part of the brain. Specifically, the brain is suspended in a layer of CSF, where its weight is almost nullified. Cerebrospinal Fluid keeps the brain buoyant. On average, 500 ml of Cerebrospinal Fluid is produced in a day by the specialized ependymal cells. It acts as a buffer and protects the brain by cushioning mechanical shocks and neutralizing small jolts. The Cerebrospinal Fluid protects the brain against immunological attacks. It fills the empty areas on the brain's surface. The Cerebrospinal Fluid or CSF flows through the skull and spinal cord. The brain is confined within the cranium and covered by cerebrospinal fluid. The skull protects the brain from the frontal, lateral, and dorsal directions. The brain is surrounded by a skull, which is made up of 22 bones - 14 are facial bones and 8 are cranial bones. It regulates all the body parts, their movements, thoughts, emotions, and the overall functioning of the body.ĭifference between Sensory and Motor Neurons Grey matter makes up most of the brain and helps in processing and releasing new information.Īll the functions in the human body are controlled by the central nervous system which consists of the spinal cord and the brain. Grey matter is slightly pinkish-grey in color, it surrounds the cerebrum, also known as the cortex of the brain. It is majorly present in the outermost layer of the brain. Grey Matter- Grey matter consists of different types of cells.White matter connects all the grey matter inside the brain. White Matter is covered or protected by myelin, which is also responsible for the color of white matter. It is made of axons that are the extensions of neurons. White Matter- White matter is present in the deeper tissues of the human brain.Our brain has two types of tissues which are discussed below: On average, the brain in adult humans weighs between 1.0 kg and 1.5 kg. According to recent estimates, the brain has anywhere from 86 billion to 100 billion neurons. The human brain is mostly made up of neurons, which are the basic building blocks of the brain and nervous system. The brain is the source of human intelligence.
