brain The cerebellum is the hind part of the brain. It is made up of gray, unmyelinated cells on the exterior and white, myelinated cells in the interior. The cerebellum coordinates muscular movements and, along with the midbrain, monitors posture. It is essential to the control of movement of the human body in space.

Difference Between Mind and Brain Most of the scientists and thinkers believe that brain and mind are one and cannot be separated. While brain is considered to be a physical thing, the mind is considered to be mental. Brain is made up of nerve cells and blood vessels whereas mind is not like that.

Brain The brains of vertebrates are made of very soft tissue. Living brain tissue is pinkish on the outside and mostly white on the inside, with subtle variations in color. Vertebrate brains are surrounded by a system of connective tissue membranes called meninges that separate the skull from the brain.he brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons.

- Brain is a physical organ of the body, which the soul occupies to live a terrestrial life. It is a physical (biological) organ that is utilised by the mind to express itself. When the physical organ – the brain – is well developed, it helps the mind to express itself better.

- The brain is the most complex part of the human body. This three-pound organ is the seat of intelligence, interpreter of the senses, initiator of body movement, and controller of behavior.he cerebrum sits at the topmost part of the brain and is the source of intellectual activities. It holds your memories, allows you to plan, enables you to imagine and think. It allows you to recognize friends, read books, and play games. The cerebrum is split into two halves (hemispheres) by a deep fissure.

Definitions &Translations The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead.The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell.The brain is the most complex organ in a vertebrate's body.In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons.he brain is the most complex organ in a vertebrate's body.

Picture of the Brain The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. The brain is made up of many specialized areas that work together: • The cortex is the outermost layer of brain cells. Thinking and voluntary movements begin in the cortex. • The brain stem is between the spinal cord and the rest of the brain. Basic functions like breathing and sleep are controlled here. • The basal ganglia are a cluster of structures in the center of the brain.

Brain The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons.ynapses are the key functional elements of the brain. The essential function of the brain is cell-to-cell communication, and synapses are the points at which communication occurs. The human brain has been estimated to contain approximately 100 trillion synapses; even the brain of a fruit fly contains several million.
