Document Summary

Central nervous system (cns): brain and spinal cord. Peripheral nervous system (pns): peripheral sensory and motor nerves. Each neuron has a charged cellular membrane a voltage difference between the inside and the outside. The charge of the membrane can change in response to neurotransmitters and. 35. 2 how neurons communicate environmental stimuli, resulting in transmitted impulses. The lipid bilayer is impermeable to charged molecules or ions. Extra k+ ions diffuse out of the cell, bringing it back to its resting membrane potential. The speed of conduction of action potentials depends upon the diameter of the axon and the axo(cid:374)"s resista(cid:374)ce to curre(cid:374)t leak: demyelinating diseases slow the conduction of action potentials because current leaks from the axons. Synapse: the region where information is transmitted from one neuron to another: presynaptic. Neuron: the neuron transmitting the signal: postsynaptic. Synaptic plasticity is necessary for learning and memory and allows synapses to be strengthened or weakened.
