Nervous system
the brain and spinal cord
central nervous system
the primary inhibitory neurotransmitter in the central nervous system, making postsynaptic neurons less likely to fire
GABA
the creation of new extensions on a neuron to allow it to make new connections with other neurons
Sprouting
a nerve cell forming part of a pathway along which impulses pass from the brain or spinal cord to a muscle or gland
Motor neuron
The long main shaft of the neuron
axon
a sub-division of the peripheral nervous system that carries sensory information to the central nervous system and motor information from it
somatic NS
the main excitatory neurotransmitter in the CNS
Glutamate
when new connections are made between neurons to create alternate neural pathways
Rerouting
nerve cells that are activated by sensory input from the environment
Sensory Neurons
an unconscious, involuntary response to certain stimuli, initiated within the spinal cord and controlled solely by neural circuits
Spinal reflex or reflex arc
a sub-division of the autonomic nervous system that calms or restores the body to its normal state of functioning
Parasympathetic NS
a neurotransmitter or neuromodulator with multiple functions depending on where it acts; functions include emotional processing, mood, and sleep onset
Serotonin
the ability of a synapse to change in response to experience
Synaptic Plasticity
the tiny space between the axon terminal of a presynaptic neuron and the dendrite of a postsynaptic neuron
Synaptic Gap
entire network of nerves located outside the central nervous system;
Peripheral NS
when a neurotransmitter stimulates or activates a postsynaptic neuron to perform its functions;
Excitatory effect
the long-lasting decrease in the strength of synaptic connections and transmission and neuronal response;
Long-term depression
a neuron which transmits impulses between other neurons, especially as part of a reflex arc
interneuron
messages travel from dendrites or axon terminals or axon terminals to dendrites?
dendrites to axon terminals.
sub-division of the autonomic nervous system embedded within the walls of the gastrointestinal (digestive) tract
Enteric NS
GABA's full name is
Gamma-amino butyric acid
Can you spell the word starting with P in LTP?
Potentiation
small clusters of neurons
Ganglia
What does the acronym SAME help us to remember?
Sensory=afferent and motor = efferent
