Document Summary
Brain is the most complex organ in the body. Neurons: nerve cell, the basic working unit of the brain, transmits information from the senses to the brain and from the brain to specific body parts. Axon terminal: conducts impulses from the neuron"s nucleus to dendrites. Dendrites: branching fibers of a neuron that receive impulses from axon terminals of other neurons and conduct these impulses toward the nucleus. Three major brain parts: cerebrum, two hemispheres- left, regulates right side of the body & right, regulates left side of the body, coordinates movement, balance, posture, cerebellum, brainstem (medulla) Brain and spinal cord contain stem cells, thousands of new neurons a day. Neurons talk to each other thru electrical and chemical purposes. Neurotransmitters: chemicals released by neurons that stimulate or inhibit the action of other neurons. Synapse : a specialized site at which the axon terminal of one neuron comes extremely close to a dendrite from another neuron.
