The golgi stain: results in sparse labeling and identification of neurons. Santiago ram n y cajal: what are the three parts of a neuron and briefly describe. Dendrites: tree like branches that collect information from other neurons. Where the dendrites of one neuron meet the axon of another: explain the way information travels between neurons. Unidirectional from the presynaptic neuron to the postsynaptic neuron across the synaptic cleft: define excitatory neuron and inhibitory neuron. Inhibitory neuron: inhibits postsynaptic neuron: define ion, cation, and anion. Ion movement by diffusion creates an electrical field, electrical and diffusion forces compete until equilibrium is reached: what is the nernst equation? (cid:3042)(cid:3041)=(cid:884). (cid:885)0(cid:885)(cid:4666)[(cid:3042)(cid:3041)] (cid:3041) [(cid:3042)(cid:3041)](cid:3042)(cid:3048)(cid:3047)(cid:4667)need temperature and concentrations to solve: name the 3 specialized proteins and describe. Sodium potassium pump, removes sodium and replaces with potassium. Potassium channels, always open and permeable to potassium. 65 mv, neuron at rest is negatively charged: describe voltage increase and voltage decrease: voltage increase: less polarization/depolarization.
