Which of the following embryonic brain vesicles forms the cerebrum?
telencephalon
Which of the following is NOT part of the brain stem?
mesencephalon **
medulla oblongata
pons
thalamus
The thalamus is part of the diencephalon, not part of the brain stem.
Which of the meninges is adhered to the surface of the brain and accompanies the branches of the blood vessels as they penetrate the surface of the brain?
pia mater
Which of the following is NOT a function of cerebrospinal fluid?
-supporting the brain
-transporting nutrients, chemical messengers, and waste products
-cushioning the brain
-providing the blood–brain barrier
providing the blood–brain barrier
Which of the following is NOT a function of the medulla oblongata?
-receiving and interpreting visual stimuli -regulating heart rate and force of contraction
-linking the brain with the spinal cord
-setting the basic rate for respiratory movements
-receiving and interpreting visual stimuli
Which of the following is NOT a set of regions linked by the pons?
-right and left cerebral hemispheres
-cerebellum to cerebrum

What directs voluntary movements by initiating impulses in somatic motor neurons?
primary motor cortex
Which cranial nerve contains sensory fibers coming from the inner ear and is responsible for hearing and balance?
