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…

NERVE CELLS – THE BRAIN’S WORKFORCE

ByTeam HUMANITYUAPD

NERVE CELLS – THE BRAIN’S WORKFORCE THE FUNDAMENTAL units of the brain, too small to see in Willis’s time, are two types of nerve cells. One type, the neuroglia (or glial-“glue”- cells), has the rather pedestrian task of supporting the nervous system. Neuroglia play a role in guiding neurons toward making connec- tions, promoting neuron…
