The basic element of nervous systems is a specialized cell-type called a neuron. nucleus Hillock axon (yellow = mylein black = nodes of ranvier) Synapse axon collateral pyramidal cell stellate cell (white matter) Soma (note: synaptic cleft) Expand Dendrites (note spines) incoming signal information flow 0. Review of Cell Biology of Neurons A. Some Properties of neurons 1) produce electrical potentials across their cell membranes 2) can transmit electrical pulses quickly 3) have receptors which convert chemical messages to electrical 4) Neurons are differentiated cells a) developmentally mature b) do not divide (non-mitotic) 5) specialized for integration and transmission of information B. Functions of neurons supported by 1) how neurons are connected 2) biophysical properties, including electrical properties and channels 3) structure, including varied shapes C. Parts of Neurons (direct students to picture) 1) Soma a) rough ER cause membrane proteins are so important
