Term
Are sensory neurons afferent or efferent and to what?
Definition
Afferent to CNS
Term
Are motor neurons afferent or efferent and to what?

Term
Inhibitory Synapses info:
Definition
NT decreases postsynaptic cell membrane permeability to Na+
Hyperpolarizes it
Depolarization is less likely to occur – IPSP
Term
Excitatory Synapses info:
Definition
NT increases postsynaptic cell membrane permeability to Na+
Depolarization is more likely to occur – EPSP
