Document Summary
Outline: organization of the mature, the developing brain. Dendrite: the receiving end of the neurone, the looks like a tree with many branches. Axon: slender, elongated structure at the other end of the cell body that sends information to other neurons. Myelin: is a fatty sheath that wraps around axon and allowing to send information to other neurons more rapidly. Terminal buttons: are small knobs, which release neurotransmitters, chemicals that carry information nearby neurons. Synapse: gap between one neuron and to the next. Cerebral cortex: wrinkled surface of the brain that is made up of about 10 billion neurons. Regulates many of the functions that we think of as distinctly human. Consists of the left and right hemispheres which are linked by millions of axons in a thick bundle called the corpus callosum. Frontal cortex: personality and ability to make and carry out plans are largely functions of an area at the front of your cortex.
