What is a nerve cell; the basic building block of the nervous system?
100
limbic system
What is a neural system (including the hippocampus, amygdala, and hypothalamus) located below the cerebral hemispheres; associated with emotions and drives?
100
dopamine
What influences movement, learning, attention and emotion? (an oversupply is linked to schizophrenia; and an under supply is linked to tremors and a loss of motor control and Parkinson's disease)
100
frontal lobe
What is the part of the brain that is involved with thinking and language, and is the executive center of the brain?
100
sympathetic
What is part of the autonomic nervous system subdivision that arouses the body, mobilizes its energy in stressful situations; the neurotransmitter norepinephrine activates here which elevates the heart rate and other vital signs?
200
neural impulse
What is an action potential or an electrical signal traveling down the axon?
200
cerebellum
What coordinates voluntary movement and balance and supports memories of such?
200
norepinephrine
What is the neurotransmitter that is produced largely by neurons in the brain stem and also acts as a hormone?
200
parietal lobe
What is the portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position; the somatosensory cortex is located here?
200
somatic
What is in the peripheral nervous system division and controls the body's skeletal muscles; it is also called the skeletal nervous system?
300
synapse
What is a junction between the axon tip of a sending neuron and the dendrites or cell body of a receiving neuron?
300
spinal cord
What is the pathway for neural fibers traveling to and from brain; controls simple reflexes?
300
serotonin
What affects mood, anxiety, hunger, eating disorders, sleep, insomnia, and arousal?
300
occipital lobe
What is the portion of the cerebral cortex lying at the back of the head; includes areas that receive information from the visual fields?
300
parasympathetic
What is part of the autonomic nervous system subdivision that calms the body, conserving its energy?
400
action potential
What is a neural impulse?
400
brainstem
What is the oldest part and central core of the brain, where the spinal cord swells as it enters the skull, responsible for automatic survival functions?
400
endorphins
What influences the perception of pain and pleasure and functions similar to morphine?
400
temporal lobe
What is the portion of the cerebral cortex lying roughly above the ears; includes areas that receive information from the ears?
400
autonomic
What is in the peripheral nervous system division controlling the glands and the muscles of the internal organs (such as the heart); its sympathetic subdivision arouses; its parasympathetic subdivision calms?
500
glial cells
What are cells in the nervous system that support, nourish, and clean up after neurons; they may play a role in learning, thinking, and memory?
500
hippocampus
What is linked to memory, and therefore acetylcholine would be prevalent?
500
acetylcholine
What enables muscle action, learning and memory?
500
cerebral cortex
What is the thin layer of interconnected neurons covering the cerebral hemispheres; the body's ultimate control and information-processing center?
500
sensory neuron
What is the neuron that carries incoming information from the sensory receptors to the central nervous system?
