Pharmacology Neuropharmacology Flashcards
Basic Principles of Neuropharmacology and the Peripheral Nervous System)
What is neuropharmacology?
The study of how drugs affect the nervous system and behavior.
True or False: The peripheral nervous system (PNS) includes the brain and spinal cord.
False
What are the two main divisions of the peripheral nervous system?
Somatic nervous system and autonomic nervous system.
Fill in the blank: Neurotransmitters are chemicals that transmit signals across a _______.
synapse.
Which neurotransmitter is primarily associated with the fight or flight response?
Norepinephrine.
What role do agonists play in neuropharmacology?
Agonists bind to receptors and activate them, mimicking the action of neurotransmitters.
Multiple Choice: Which of the following is a common neurotransmitter? A) Insulin B) Dopamine C) Hemoglobin
B) Dopamine
What is the function of the autonomic nervous system?
To regulate involuntary bodily functions, such as heart rate and digestion.
True or False: The somatic nervous system controls voluntary movements.
True
What is the primary function of acetylcholine in the peripheral nervous system?
To transmit signals to muscles, enabling movement.
Fill in the blank: The _______ nervous system prepares the body for rest and digestion.
parasympathetic.
What are the two branches of the autonomic nervous system?
Sympathetic and parasympathetic nervous systems.
Multiple Choice: Which neurotransmitter is primarily involved in mood regulation? A) Serotonin B) Adrenaline C) Glutamate
A) Serotonin
What is synaptic plasticity?
The ability of synapses to strengthen or weaken over time, affecting learning and memory.
True or False: Neuropharmacology only studies the effects of illegal drugs.
False
What is the primary effect of dopamine in the brain?
It plays a key role in reward, motivation, and pleasure.
Fill in the blank: The _______ nervous system is responsible for the ‘rest and digest’ responses.
parasympathetic.
What is a receptor antagonist?
A substance that binds to a receptor but does not activate it, blocking the action of neurotransmitters.
Multiple Choice: Which of the following is NOT a type of neurotransmitter? A) Peptides B) Steroids C) Amino acids
B) Steroids
What is the role of the blood-brain barrier?
To protect the brain from harmful substances while allowing necessary nutrients to pass through.
True or False: The sympathetic nervous system is responsible for increasing heart rate during stress.
True
What type of drugs can enhance the effects of neurotransmitters?
Agonists.
Fill in the blank: _______ is the neurotransmitter primarily associated with muscle contraction.
Acetylcholine.
What is the main function of the sensory neurons in the peripheral nervous system?
To transmit sensory information from the body to the central nervous system.
Multiple Choice: Which neurotransmitter is associated with learning and memory? A) Glutamate B) GABA C) Norepinephrine
A) Glutamate
