Document Summary
Shrinks because water leaves cell for solution. Has less solute in comparison to another solution. To break or rupture: applications, 1. Hypertonic solutions for edema: pull water out of swollen tissues: 2. 4: topic #2. 2: physiology of the neuron, special features, 1. Extreme longevity: adequately nourished - 100 yr: 2. Takes a very long time to regenerate: 3. High metabolic rate: o2/glucose requirements? because are large, complex cells: all have a cell body + one or more processes. Receptive region (red) - dendrites/ axon hillock: 2. Structure containing a number of nerve cell bodies: b. neuron processes, dendrites, axons, axonal terminals, 2 more terms: tract: bundle of nerve processes in cns, nerve: bundle of nerve processes in pns. Dendrites: (receptive region: short, tapering, branched extensions;usually hundreds/cell body, enormous sa for reception from other neurons, conduct impulses toward cell body, short distance, graded potentials, b2.
