Neurons and How they Work
This part of the neuron receives incoming messages from other neurons.
Dendrites
True or False: Neurotransmitters are chemical messengers
True - electricity is used by the nervous system, but the messenger itself is a chemical
This part of the nervous system includes the brain and spinal cord.
Central Nervous System
This “master gland” regulates growth and controls other glands.
Pituitary Gland
This lobe controls vision.
Occipital Lobe
The gap between neurons is called this
The synapse/synaptic gap
This neurotransmitter is often related to exercise
endorphins
This branch of the Peripheral Nervous System controls voluntary movement like waving your hand.
Somatic Nervous System
This gland regulates metabolism and energy levels.
Thyroid Gland
This part of the limbic system is involved in emotion, especially fear and aggression.
Amygdala
The electrical impulse which sends the message down the axon to the axon terminal is called
Action Potential
This neurotransmitter is often associated with movement and addiction. Too much of it is linked to schizophrenia
Dopamine
This part of the autonomic nervous system calms the body after a stressful event.
Parasympathetic Nervous System
The endocrine system uses these chemical messengers carried in the bloodstream.
Hormones
An injury causes a person to make impulsive decisions, struggle with planning, and have trouble controlling emotions. Which brain region is affected?
The frontal lobe
This step in neural communication is like a toilet bowl that cannot be flushed again immediately after flushing.
Refractory Period
This neurotransmitter is linked to mood and well-being. Low levels are associated with depression.
Serotonin
You see a bee and decide to run. Which branch of the nervous system increases heart rate and releases adrenaline?
Sympathetic Nervous System
A person has trouble sleeping consistently. Which gland might be involved?
The pineal gland (melatonin)
A patient can understand language but cannot speak clearly. Which area is damaged?
Brocas Area
This law refers to the fact that a neuron will either fire or it won't -there is no in between
All or Nothing Law
What is reuptake and how does it relate to neurotransmitters?
Reuptake is when neurotransmitters are reabsorbed by the neuron who sent them across the synaptic gap
A student jumps when they see a spider. Which type of neuron sends the message from the eye to the brain?
Sensory Neurons
Compare one similarity and one difference between the nervous system and endocrine system.
Both send messages; nervous = fast/electrical; endocrine = slow/hormonal.
A person suffers from severe memory loss and cannot form new long-term memories. Which brain structure is damaged?
Hippocampus
