ANATOMY [ DIFFERENT PARTS & DIFFERENT RESPONSIBILITIES ( THE AMAZING BRAIN ) ]

ByTeam HUMANITYUAPD

ANATOMY [ DIFFERENT PARTS & DIFFERENT RESPONSIBILITIES ( THE AMAZING BRAIN ) ] DIENCEPHALON In the center of the brain, between the cerebrum’s two hemispheres, lies the diencephalon. It consists largely of three important structures : the Thalamus, Hypothalamus, and Epithalamus. The Thalamus acts as a relay for sensory information on its way to the…

ANATOMY [ DIFFERENT PARTS DIFFERENT RESPONSIBILITIES ( THE AMAZING BRAIN ) ] THE FRONTAL LOBE A portion of the frontal lobe of each hemisphere called the precentral gyrus controls the body’s movements. Oddly, each hemisphere moves the opposite side of the body, as if the brain’s wiring some-how became crossed. Hence, the movements of the…

ANATOMY [ DIFFERENT PARTS & DIFFERENT RESPONSIBILITIES ( THE AMAZING BRAIN ) ] FOUR DIVISIONS Moving inward, we come to the organ itself. The brain may appear to be a Ulllform mass of folded, pink tissue. But a closer look reveals different lobes, regions, structures, and parts that all help regulate body functions, interpret information…

NERVE CELLS – LIFE SPAN [ THE AMAZING BRAIN ]

ByTeam HUMANITYUAPD

NERVE CELLS – LIFE SPAN [ THE AMAZING BRAIN ] Amazingly, the cells that perform the complicated ballet of electrochemical transmission can live more than a hundred years, but they do not get replaced like most other body cells. Except for the hippocampus and the olfactory bulb, where new neurons have been shown to grow…

NEURON COMMUNICATIONS/NEURON TRANSMITTERS [ NERVE CELLS ( THE AMAZING BRAIN ) ] NEURON COMMUNICATIONS Tim Berners-Lee, a creator of the World Wide Web, likens the brain’s complexity to the nearly infinite capacity for Web sites to connect to each other. “A piece of information is really defined only by what it’s related to,” he said….

NEURONS AT WORK [ CONNECTIONS / ACTION / GROWTH & SUPPORT / PLASTICITY ]

ByTeam HUMANITYUAPD

NEURONS AT WORK [ CONNECTIONS / ACTION / GROWTH & SUPPORT / PLASTICITY ] Neurons serve different functions. Motor neurons carry impulses to activate glands and muscles. Sensory neurons send impulses from the skin and other body parts to the central nervous system. Interneurons, residing in the brain and spinal cord, integrate the signals and…

ANATOMY OF A NEURON [ NERVE CELLS ( THE AMAZING BRAIN ) ]

ByTeam HUMANITYUAPD

ANATOMY OF A NEURON [ NERVE CELLS ( THE AMAZING BRAIN ) ] Each neuron has a main cell body. Like all cells, the neuron contains a nucleus and an exterior mem-brane, which sometimes receives electrochemical messages from other neurons. Chains of neurons send messages from the body to the brain: “Here is pain, in…
