Fill in the blank: The __________ lobe processes auditory information.
Temporal.
What is the function of the Parietal lobe?

Synapse.
True or False: The brain is part of the Peripheral Nervous System.
False.
What is the role of the Autonomic Nervous System?
It regulates involuntary bodily functions.
Fill in the blank: The __________ lobe is involved in higher cognitive functions.
Frontal.
What is the function of sensory receptors?
They respond to environmental stimuli and send information to the brain.
Multiple Choice: Which lobe is primarily responsible for vision?
Occipital lobe.
What is a neurotransmitter?
A chemical messenger that transmits signals across a synapse from one neuron to another.
True or False: The brainstem is part of the Central Nervous System.
True.
What is the main function of the cerebellum?
It coordinates voluntary movements and balance.
Fill in the blank: The __________ system includes the brain and spinal cord.
Central Nervous.
What type of neuron carries signals from the brain to muscles?
Motor neuron.
Multiple Choice: Which lobe is responsible for processing language?
Temporal lobe.
What is the function of the occipital lobe?
It is primarily responsible for visual processing.
True or False: The nervous system has only one type of neuron.
False.
What are the two main divisions of the nervous system?
Central Nervous System (CNS) and Peripheral Nervous System (PNS).
Fill in the blank: The __________ nervous system controls voluntary movements.
Somatic.
What is the main function of the brain?
To process information and control bodily functions.
