Document Summary
Neurons and glial cells form the foundation of the nervous system. Cells and their products are organized into tissues and these tissues are organized into organs and these organs are organized into organ systems. The cell theory all organic beings are composed of individual cells. Cajal doctrine says that each neuron is a separate cell and is the fundamental building block of the nervous system. He also came up with the idea that there the neural connections had a predetermined design. Specific nerve energies theory our sensory experience is determined by the pathway it"s carried on. They also found that in the majority of neurons, information flows one way through a neuron. The dendrite receives the information and passes it through the cell body to the axon. Axons send that information away from the cell body to the next insertion. Cell structure and function: molecules 4 classes of molecules, carbohydrates or glycogen .
