This Neurotransmitter enables muscle action, learning and memory.
What is Acetylcholine (ACh)?
100
This hormone is a sugar that circulates in the bloodstream and helps provide energy to the body tissues; low levels of this hormone make us feel hunger.
What is Glucose?
100
Messages travel down this part of the neuron.
What is the Axon?
100
This Nervous System enables the voluntary control of skeletal muscles.
What is the Somatic Nervous System?
100
This is the thing that covers both hemispheres of the brain.
What is the Cerebral Cortex?
200
This is a major excitatory neurotransmitter which is also involved with memory.
What is Glutamate?
200
This hormone is secreted by the pancreas; it controls blood glucose.
What is Insulin?
200
This covers and protects the axon as well as helping to speed up transmission.
What is the Myelin Sheath?
200
This Nervous System controls glands and internal, involuntary functions.
What is the Autonomic Nervous System?
200
This part of the brain controls the expression of language; damage to it inhibit speech.
What is Broca's Area?
300
This neurotransmitter affects mood, hunger, sleep, and arousal.
What is Serotonin?
300
This hormone is secreted by an empty stomach; it makes us feel hungry.
What is Ghrelin?
300
This is the electrical signal that travels down the axon.
What is Action Potential?
300
This Nervous System calms us down after an arousing experience.
What is the Parasympathetic Nervous System?
300
This area of the brain is located just in front of the parietal lobes; it registers and processes the sensations of movement and touch.
What is the Sensory Cortex?
400
This neurotransmitter helps control alertness and arousal.
What is Norepinephrine?
400
This is a hormone secreted by the lateral hypothalamus that triggers hunger.
What is Orexin?
400
This is the part of the neuron that sends messages to other cells.
What are the Terminal Branches?
400
This Nervous System contains the brain and the spinal cord.
What is the Central Nervous System?
400
This part of the brain is involved with language comprehension and expression; damage to it not only prevents meaningful speech, it also dampens understanding of speech.
What is Wernicke's Area?
500
This is a major inhibitory neurotransmitter.
What is GABA?
500
This is a hormone secreted by the digestive tract; it tells the brain to stop eating.
What is PYY?
500
This is the part of a cell that receives messages from other neurons.
What are Dendrites?
500
This Nervous System arouses the body in stressful situations.
What is the Sympathetic Nervous System?
500
This part of the brain is located at the bottom of the brainstem; it controls breathing and heartbeat.
