#1
Which part of the neuron receives signals from other neurons?
Dendrite
ExplanationDendrites are the branching extensions of a neuron that receive signals from other neurons.
#2
What is the primary function of the central nervous system?
To coordinate and process information
ExplanationThe central nervous system coordinates and processes information from the body, consisting of the brain and spinal cord.
#3
What is a synapse?
The gap between neurons where communication occurs
ExplanationA synapse is the junction or gap between neurons where electrochemical communication takes place.
#4
Which part of the neuron sends signals to other neurons or muscles?
Axon
ExplanationThe axon is the elongated part of a neuron that transmits signals to other neurons or muscles.
#5
What is the primary function of the spinal cord?
To transmit signals between the brain and the rest of the body
ExplanationThe primary function of the spinal cord is to transmit signals between the brain and the rest of the body.
#6
Which neurotransmitter is associated with pleasure and reward?
Dopamine
ExplanationDopamine is a neurotransmitter linked to pleasure, reward, and motivation.
#7
Which part of the brain is responsible for regulating basic survival functions like breathing and heart rate?
Medulla oblongata
ExplanationThe medulla oblongata is a part of the brainstem that regulates vital functions such as breathing and heart rate.
#8
What is the role of the parasympathetic nervous system?
To conserve energy and promote restful activities
ExplanationThe parasympathetic nervous system conserves energy and promotes restful activities, countering the 'fight or flight' response.
#9
Which neurotransmitter is associated with sleep, mood, and appetite regulation?
Melatonin
ExplanationMelatonin is a neurotransmitter associated with regulating sleep, mood, and appetite.
#10
Which part of the brain is responsible for higher cognitive functions such as thinking and problem-solving?
Frontal lobe
ExplanationThe frontal lobe is associated with higher cognitive functions, including thinking, problem-solving, and decision-making.
#11
What is the function of the myelin sheath?
To insulate and speed up neural impulses
ExplanationThe myelin sheath insulates and accelerates the transmission of neural impulses along the axon.
#12
What is the function of the thalamus?
To process sensory information and relay it to the cerebral cortex
ExplanationThe thalamus processes sensory information and relays it to the cerebral cortex for further processing.
#13
What is the function of the corpus callosum?
To facilitate communication between the two hemispheres of the brain
ExplanationThe corpus callosum facilitates communication between the two hemispheres of the brain, allowing information transfer.
