Document Summary
Neurons: cells in the nervous system that communicate with one another to perform information-processing tasks. Santiago ramon y cajal learned about a new technique for straining neurons in the brain. This technique highlighted the appearance of the entire cell, revealing that they came in different shapes and sizes. Each neuron was composed of a body with many threads extending towards another neuron, without physically touching other neurons. Neurons are the information-processing units of the brain. Cell body: cells in the nervous system that communicate with one another to perform information-processing tasks. Surrounded by a porous layer: allows molecules to flow in and out. Cell body contains a nucleus: structures houses chromosomes that contain your dna. Two types of specialized extensions of the cell membrane that allow them to communicate: dendrites and axons. Dendrites: receive information from other neurons and relay it to the other cell. Axon: transmits information to other neurons ,muscles or glans.
