Test 3-Physiology
Neurophysiology -Transmitters & CNS
| Question | Answer |
|---|---|
| Acetylcholine(ACh)is a major neurotransmitter in the peripheral nervous system at the neuromuscular junction and in the brain, what neurons release Ach? | Cholinergic Neurons |
| Ach is used by both the sympathetic and parasym nervous system, true or false? | True |
| What are excitatory nuerotransmitters? | Ach and Glutamate |
| What are the two Amino acids that are neurotransmitters? | Glutamate and GABA (gamma-aminobutyric acid: from glutamate) |
| What are the 6 classes of Neurotransmitters? | 1. Acetylcholine // 2.Amino Acids // 3.Amines // 4.Purines & Pyrimidines // 5.Gases // 6.Peptides |
| Name the NeuroTransmitter that is found in the PNS & CNS, used by the spinal cord neurons to control muscles and by neurons in brain to regulate memory, is Excitatory, activates Nicotinic and Muscarinic receptors? | Acetycholine (Nicotinic receptors are found at the neuromuscular junctions of skeletal muscles). |
| What NeuroTrans produces feelings of pleasure when released by brain reward system and is usually Inhibitory? | Dopamine |
| What NeuroTrans is major inhibitory neurotrans in the brain? | GABA |
| What is the most common excitatory neurotrans in the brain? | Glutamate |
| What neurotrans is used mainly by neurons in the spinal cord and acts as an inhibitor? | Glycine |
| What neurotrans acts as a neurotrans and a hormone? In the PNS, it is part of the SNS (fight or flight). In the brain it acts as a neurotrans regulating normal brain processes and is usually excitatory but is inhibitory in a few brain areas? | Norepinephrine (noradrenaline) |
| What neurotrans is similar to Norepinephrine, but more wide spread when acting as a hormone secreted from adrenal medulla? | Epinephrine (adrenaline) |
| Both Nor and Epinephrine bind to what G-protein couple receptors? | Adrenergic receptors |
| What Neurotrans is involved in may functions including mood, appetite, and sensory perception? In Spinal cord it inhibits pain pathways. | Serotonin |
| What neuroTrans is not stored in synaptic vesicles, activates enzymes for the production of second messengers (cGMP) and relaxes smooth muscles in the walls of arterioles; vasodilation? | NO - Nitric Oxide |
| ------------------------------------- Thalamus, hypothalmus, CINGULATE GYRUS, hippocampus, and AMYGDALA are all part of what system? | Limbic system |
| IF a patient is in a coma what is not functioning in the brain stem? | RAS - Reticular Activating System |
