PSYCH 1 Lecture Notes - Lecture 2: Santiago Ramón Y Cajal, Axon Hillock, Axon Terminal
Document Summary
In the early 1900s, as our technology and tools took to look at biological mechanisms of the body improved, people found the source of the hypothetical cells aka neurons. The notion of the role of the nervous system was pushed by ramon y cajal proposed our entire nervous system is contained in small microscopic cells neurons. Neurons are specialized cells that receive and transmit information throughout the body and brain. They are located throughout the body, with the highest concentration in the brain regions. They come in a number of shapes and sizes and are thought to be the primary tools involved in almost all mental talks. By adulthood we have about 100 billion neuron cells as babies we have more, but in order to become faster and more efficient, we get rid of the extra neurons. A microscopic change in the axon hillock causes a propagated message to work its way down the axon.
