Oculomotor nerve (CN III)
Fill in the blank: The ______ lobe is responsible for sensation and perception.
Parietal
What is the role of the thalamus?
Relay sensory information to the cerebral cortex.
Which cranial nerve is associated with taste?
Facial nerve (CN VII)
True or False: The medulla oblongata regulates heart rate and breathing.
True
What is the primary function of the hypothalamus?
Regulates homeostasis and endocrine functions.

Vestibulocochlear nerve (CN VIII)
Fill in the blank: The ______ is a protective layer surrounding the brain.
Meninges
What is the function of cerebrospinal fluid (CSF)?
Cushions the brain and spinal cord, removes waste.
Which part of the brain is responsible for emotional responses?
Limbic system
True or False: The pituitary gland is often referred to as the ‘master gland’.
True
What is the function of the spinal cord?
Transmits signals between the brain and the body.
Which cranial nerve is involved in swallowing and taste?
Glossopharyngeal nerve (CN IX)
Fill in the blank: The ______ controls involuntary functions like breathing and heart rate.
Brainstem
What does the term ‘lateralization’ refer to in brain function?
The specialization of the left and right hemispheres for different functions.
Which cranial nerve innervates the muscles of facial expression?
Facial nerve (CN VII)
True or False: The somatic nervous system controls voluntary movements.
True
What is the role of the autonomic nervous system?
Controls involuntary bodily functions.
Which cranial nerve is responsible for neck and shoulder movement?
Accessory nerve (CN XI)
Fill in the blank: The ______ lobe is associated with higher cognitive functions.
Frontal
What is the function of the corpus callosum?
Facilitates communication between the two hemispheres.
Which part of the brain regulates body temperature?
Hypothalamus
True or False: The brain consumes about 20% of the body’s total energy.
True
What is the main function of the parietal lobe?
Processing sensory information from the body.
Which cranial nerve is known as the ‘wandering nerve’?

Fill in the blank: The ______ is the outer layer of the brain.
Cerebral cortex
What is the function of the pons?
Regulates sleep and relays messages between different parts of the brain.
