Term
Definition
Central nervous system (CNS)   show
🗑
Peripheral nervous system (PNS)   show
🗑
show the part of the peripheral nervous system that picks up stimuli from the outside world, coordinates movements, and performs other consciously controlled tasks  
🗑
show the part of the peripheral nervous system that performs tasks that are not consciously controlled  
🗑
show is the part of the autonomic nervous system that is always active and acts as a brake for organs.  
🗑
Parasympathetic nervous system   show
🗑
show excitable cells that receive different types of stimulation; the building blocks of the nervous system  
🗑
show relatively short, bushy, branch-like structures that emerge from the neuron's cell body and receive signals from adjoining neurons  
🗑
Soma   show
🗑
show a cable-like extension that transmits a signal away from a neuron's soma toward the target of communication  
🗑
show a fatty substance that coats and insulates axons  
🗑
Terminal buttons   show
🗑
Sensory neurons   show
🗑
show neurons that carry information away from the central nervous system to operate muscles and glands  
🗑
Interneurons   show
🗑
Threshold   show
🗑
Synapse   show
🗑
show a chemical message created by a synapse from an electric message transmitted by terminal buttons  
🗑
Spinal cord   show

show part of the limbic system; involved in fear detection and conditioning; it is essential for unconscious emotional responses such as the fight-or-flight response  
🗑
Hypothalamus   show
🗑
show a physiological response to stressors, triggered by the amygdala, in which the body becomes prepared for action  
🗑
show involved in the release of hormones that regulate metabolism, growth, development, tissue function, and mood from the caudate and putamen to the thalamus  
🗑
show secretes human growth hormone and influences all other hormone-secreting glands  
🗑
Gray matter   show
🗑
Occipital lobes   show
🗑
show parts of the brain involved in auditory processing  
🗑
Frontal lobes   show
🗑
show a part of the brain that is responsible for generating the neural impulses that control the execution of movements  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
