Document Summary
Mind and behavior connected by the central nervous system. Neurons are cells in the nervous system that community with each other to perform information-processing tasks. Earliest work - staining brain tissue revealed a neuronal net" that appeared as a contiguous sheet of woven threads. Work by cajal & others with more advanced stains revealed existence of individual neurons as the units that formed the interconnected network. Neurons share basic characteristics, but also have unique shapes, sizes, and structural extensions. The hand and the structure of the neuron. Performs functions such as protein synthesis, energy production, and metabolism. Receive info from environment and other neurons, and relay it to the cell body. Carries information to other neurons, muscles, or glands. Process inputs from our external environment and convey information to the brain via the spinal cord. Dendrites contain specialized receptor units that receives signals such as light, sound, touch, taste, and smell. Ganglion cells - located very near the spinal cord.
