DECK 3- CENTRAL NERVOUS SYSTEM Flashcards
Define CNS.
Contains the brain and spinal cord; it processes sensory input and is the origin of thoughts, emotions, and memories. It is also where nerve impulses that cause muscles to contract and glands to secrete come from.
Conducting an action potential down the axon of the neuron
Axonal Conduction
A process by which information is carried across the gap between neuron and postsynaptic cell.
Synaptic Transmission
The passage is limited to lipid-soluble agents or via specific transport system
Blood Brain Barrier
Decreasing response after using drugs for a long time.
Tolerance
A condition where abruptly discontinuing drug use will cause a withdrawal syndrome.
Physical Dependence
Treatment for COPD and druid overdose-induced respiratory depression.
Doxapram
Advancing neurodegenerative
Dopamine deficit is a disorder marked by a lack of the neurotransmitter in the brain, which results in both motor and non-motor symptoms.
Parkinson’s Disease
5 steps of synaptic transmission.
-Action and receptor
-Termination of transmission
-Synthesis of neurotransmitter
-Storage of vesicle
-Release of neurotransmitters from the terminal neuron
Drugs That block Receptor
Anticolinergic Agents
Characterized as the involuntary contraction of a muscle or group of muscles
Muscle spasm
Most commonly prescribed anticonvulsant drug
Valproic acid
Slow down bodily and mental processes.
Benzodiazepine
The basis of epilepsy treatment.
Carbamazepine
Cells that move electrical signals across the body in a cell-to-cell fashion.
Neurons
Bind to a carrier protein and act at a receptor resulting in increased GABA in the brain.
Gabapentin
A class of diseases marked by the CNS’s excessively excitable neurons.
Epilepsis
The general term that applies to all types of epileptic events.
Seizure
Abnormal motor phenomenon
Convulsion
A brief absence of oxygen during pregnancy frequently results in birth abnormalities such as poorly controlled voluntary muscles, convulsions, mental retardation, and/or impaired hearing and vision.
Cerebral Palsy
