Neurons & Communication
This electrical signal travels down the axon.
What is an action potential?
This system contains the brain and spinal cord.
What is the central nervous system (CNS)?
This brainstem structure controls basic life functions like heartbeat and breathing.
What is the medulla?
This structure triggers emotional responses like fear and aggression.
What is the amygdala?
This lobe is responsible for planning, decision-making, and movement.
What is the frontal lobe?
These branching fibers receive messages from other neurons.
What are dendrites?
This system includes all nerves outside the brain and spinal cord.
What is the peripheral nervous system (PNS)?
This structure helps coordinate movement and balance.
What is the cerebellum?
This seahorse-shaped structure helps form new memories.
What is the hippocampus?
This lobe receives and processes touch and body-position information.
What is the parietal lobe?
This insulating material speeds up neural transmission along the axon.
What is myelin?
This division controls involuntary functions like breathing and digestion.
What is the autonomic nervous system?
This part of the brainstem helps with sleep and coordination.
What is the pons?
This structure maintains homeostasis and controls hunger, thirst, and temperature.
What is the hypothalamus?
This lobe processes sound and language.
What is the temporal lobe?
This is the neuron’s stable, negatively charged state before it fires.
What is resting potential?
This division of the autonomic system activates the “fight-or-flight” response.
What is the sympathetic nervous system?
This brainstem structure is involved in visual/auditory processing and movement.
What is the midbrain?
This area helps regulate emotions and cognitive control, located above the corpus callosum.
What is the cingulate cortex?
This lobe contains the primary visual cortex.
What is the occipital lobe?
This process occurs when neurotransmitters are absorbed back into the presynaptic neuron.
What is reuptake?
This network of neurons operates in the digestive system.
What is the enteric nervous system?
This long fiber bundle connects the two hemispheres of the brain.
What is the corpus callosum?
This structure lights up in reward processing and motivation.
What is the nucleus accumbens?
This region at the front of the frontal lobe is essential for personality, judgment, and impulse control.
What is the prefrontal cortex?
