What is the autonomic nervous system? - CORRECT ANSWER-The part of the nervous system
that controls organs automatically; includes the sympathetic (arousal) and parasympathetic
(calming) systems.
What is the central nervous system? - CORRECT ANSWER-The brain and spinal cord; processes
information and directs responses.
What is the enteric nervous system? - CORRECT ANSWER-A network of neurons that controls
the digestive system.
What is the forebrain? - CORRECT ANSWER-The front part of the brain involved in thinking,
perception, and voluntary movement.
What is the hindbrain? - CORRECT ANSWER-The back part of the brain that controls basic life
functions like breathing, heart rate, and coordination.
What is the peripheral nervous system? - CORRECT ANSWER-The system that connects the
brain and spinal cord to the rest of the body.
What is the somatic nervous system? - CORRECT ANSWER-The part of the nervous system that
carries sensory information to the CNS and controls voluntary muscle movement.
, What is the sympathetic nervous system? - CORRECT ANSWER-The part of the autonomic
nervous system that prepares the body for 'fight or flight' (increases heart rate, slows digestion).
What is an action potential? - CORRECT ANSWER-A nerve impulse sent along an axon, involving
rapid depolarization of the neuron membrane.
What is the all-or-none law? - CORRECT ANSWER-Once an action potential starts, it always has
the same strength and speed, regardless of stimulus intensity.
What is depolarization? - CORRECT ANSWER-A decrease in the charge difference across the
neuron membrane, making the inside less negative and triggering an action potential.
What is hyperpolarization? - CORRECT ANSWER-An increase in the neuron's negative charge
inside the cell, making it less likely to fire an action potential.
What are the nodes of Ranvier? - CORRECT ANSWER-Gaps in the myelin sheath along an axon
that allow electrical signals to jump quickly from node to node.
What is the refractory period? - CORRECT ANSWER-A brief time after an action potential when a
neuron cannot (or is less likely to) fire another impulse.
What is resting potential? - CORRECT ANSWER-The stable electrical charge difference across a
neuron's membrane when it is not actively sending signals.
Which brain research method relies on the blood protein that binds oxygen? - CORRECT
ANSWER-Functional magnetic resonance imaging (fMRI)
Which technique is among those that researchers use to record brain activity during specific
behaviors? - CORRECT ANSWER-Magnetoencephalograph (MEG)
