Nervous System Structure
The names of the main lobes of the brain
What are frontal, temporal, occipital, parietal
The part of the neuron that receives signals
The goal of an action potential. What does the Neuron doing?
What is sending a signal?
Involved in muscle contraction, learning, and memory.
What is acetylcholine?
The location where reflexes are processed
What is the Spinal Cord?
The Nervous System is divided into two subsystems. Pick one subsystem and provide what it is composed of.
What is the brain and spinal cord.
What are nerves.
The part of a neuron that transmits information
What is an axon?
The stage of an action potential where Potassium rushes out of a Neuron
What is repolarization?
Plays a role in pleasure, motivation, mood, attention, memory, and movement.
What is dopamine?
This mechanism of action binds to a receptor and activates it to produce a response.
What is an agonist?
The Nervous System is divided into two subsystems. What are the names of these subsystems
What is the Peripheral Nervous System
What is the Central Nervous System
While neurons vary in size, shape, and structure. Nearly all neurons have these three essential parts
What is cell body, axon, and dendrites.
The stage of an action potential where Sodium Ions rush into the neuron.
What is depolarization?
The primary inhibitory neurotransmitter of the central nervous system
gamma-aminobutyric acid (GABA)
A drug that inhibits the voltage gated sodium channels of a neuron affects which portion of an action potential?
What is depolarization?
The brain is split into three distinct structures. What are the names of these three structures?
What is the cerebrum, cerebellum, and brain stem?
The name of the sheath that covers the long axon of a neuron.
What is myelin?
What voltage is needed to be met in order for an action potential to occur? (Threshold)
What is -55mV?
Involved in regulation of mood and sleep; also aids in digestion.
What is dopamine?
This action of mechanism works by binding to a receptor and has the opposite effect to that of an agonist, depressing receptor activity.
What is an inverse agonist?
The name of the specific area of the brain responsible for the processing of sensory information (touch, pain, pressure, temperature)
What is the sensory cortex?
These neurons carry information away from the central nervous system to the organs or structures that will cause the body’s response.
What are motor Neurons (efferent)
If the Sodium/Potassium pump does not work after an action potential occurs what could the result be?
What is resting potential is not met?
What is the neuron stays in hyperpolarization?
Excitatory neurotransmitters that play a role in the fight-or-flight response, to increase arousal and attention.
What is epinephrine and norepinephrine?
Wobbly Cats suffer from this disorder
What is cerebellar hypoplasia?
