15. Match the neurotransmitter to its description:___________________________________Usually inhibitory; inhibits pain; released only in CNS___________________________________Usually excitatory; release is blocked by botulinum toxin; released at synapses in both the CNS and PNS; has nicotinic receptors on skeletal muscles at the NMJ; has muscarinic receptors at visceral organs and in the CNS.___________________________________Can be excitatory or inhibitory depending on where it is released and its target. Produced by the substantia nigra in midbrain; also by hypothalamus, etc.; “feel good” neurotransmitter; people with Parkinson’s disease have a deficiency of this. Plays a role in moderating motor impulses to skeletal muscles. Released mostly in the CNS.___________________________________Usually inhibitory. Released in the CNS. Plays a role in mood regulation.___________________________________Released in CNS, including spinal cord. It is the major excitatory neurotransmitter; important in learning and in memory formation; excessive release during a stroke causes over-stimulation of neurons and can cause neuron death.
