The Systems
Miscellaneous
100
It's the branch like part of the neuron that receives chemical messages from other neurons
Dendrites
100
This part of the hindbrain controls heartbeat breathing, and other vital life functions
Medulla
100
When you feel rewarded, you are releasing this neurotransmitter
Dopamine
100
The skull and the spinal cord protect this neurological system
Central Nervous System
100
This is the minimum stimulation needed to activate a particular neuron
Stimulus Threshold
200
It is the point of communication between two neurons
synapse
200
This highlighted part of the brain is in every cerebral hemisphere and processes sensory information except smell
Thalamus
200
this neurotransmitter stimulates the muscles in the heart and the stomach to contract. It is how neurons communicate with muscles.
Acetylcholine
200
This system of glands secretes hormones into the body. They are located all over the body
Endocrine System
200
This neurotransmitter's role is learning and memory, physical arousal, and sleep regulation
Norepinephrine
300
Oligodendrocytes form this white fatty covering that wraps around the axon of some neurons in the Brain
Myelin sheath
300
This part of the Hindbrain that connects the medulla to the two sides of the cerebellum and helps coordinate movement on both sides of the body
Pons
300
When you are drinking alcohol, you are increasing this neural regulating neurotransmitter
GABA
300
This nervous system includes all nerves outside the central nervous system and is in charge of coordinating the organs of the body
Peripheral Nervous System
300
This system is made up of forebrain structures that are involved in emotion, motivation, learning, and memory
Limbic System
400
brief electrical impulses that transmit information along the axon, it also follows the all-or-none law
action potential
400
It is the largest lobe of each cerebral hemisphere. It is involved with thinking, planning, and emotional control
Frontal Lobe
400
Prozac, an antidepression medication, increases the production of this neurotransmitter
serotonin
400
This system is your fight or flight response system. You may have dilated pupils, increased heart rate, and slower digestion
Sympathetic Nervous System
400
This lobe is in the back of each cerebral hemisphere and is the primary receiving area for visual information
Occipital Lobe
500
This entering the neuron makes the neuron positively charged
Sodium
500
This part of the frontal lobe is critical for speech production. It is named after a French physician who treated several patients with speech difficulties
Broca's area
500
Naloxone, an opioid antagonist used to reverse the effects of opioid drugs blocks receptors of this neurotransmitter
endorphins
500
This subdivision of the peripheral nervous system receives information from sensory receptors as well as communicates with the central nervous system
somatic nervous system
500
This part of the brain is located in the forebrain and is responsible for forming new memories
Hippocampus
