| Term | Definition |
|---|
| terminal arborization | branched endings of axons |
| steady state | a state like equilibrium except that energy must be continuously added to the system to maintain the constancy |
| tetradotoxin | a drug that blocks Na+ channels |
| tetra-ethyl ammonium | a drug that blocks K+ channels |
| passive transmission | membrane potential changes at one point and the change spread out away from the source; aka decremental conduction |
| regenerative propagation | change in membrane potential sweeps along axon without decrement |
| saltatory conduction | myelination speeds up conduction velocities by allowing signals to jump from node to node of Ranvier |
| post-synaptic potential | a post-synaptic change in membrane potential |
| acetylcholine | a neurotransmitter |
| curare | a competitive inhibitor of ACh |
| acetylcholinesterase | an enzyme that is found in high concentration on and around post-synaptic membranes |
| g-amino butyric acid | an inhibitory neurotransmitter |
| reversal potential | equilibrium potential for post-synaptic potentials |
| catecholamines | a family of modified amino acid neurotransmitters |
| afferent neuron | sensory or receptor neuron; carries signal to CNS |
| efferent neuron | motor or effector neuron; carries signal from CNS to PNS |
| interneuron | neuron that connects afferent and efferent neurons |
| monosynaptic reflex | a reflex which has only a single synapse between an afferent sensory neuron and an efferent somatic motor neuron; synapse between somatic motor neuron and its target muscle is ignored |
| polysynaptic reflex | a complex reflex with extensive branching in the CNS that forms networks involving multiple interneurons; divergence and convergence used |
| stretch reflex | monosynaptic reflex arc that provides a paradigm for information flow through the CNS |
