Nerve impulse (action potential) B. Production and presence of adenosine triphosphate (ATP) C. Sodium ions to bind to the thin filament D. Acetylcholine to bind to the sarcolemma receptors • Question 2 This sensory region of the cerebrum is involved with the ability to understand written and spoken language? Selected Answer: A. Wernicke’s area Answers: A. Wernicke’s area B. Broca’s area C. Primary somatosensory cortex D. Olfaction area • Question 3 Which statement is NOT true regarding the meninges and cerebrospinal fluid (CSF)? Selected Answer: D. An epidural procedure will extract CSF from the meninges Answers: A. CSF is reabsorbed back into the venous blood return within the venous sinuses B. CSF is found within the subarachnoid space of the meninges C. The dura mater is the thickest and most superficial layer of the meningesD. An epidural procedure will extract CSF from the meninges • Question 4 Which statement is correct regarding the dorsal horn of the spinal cord? Selected Answer: C. It receives afferent information from the peripheral nervous system Answers: A. It provides a pathway for information from the brain to the efferent peripheral nervous system B. It contains tracts that send impulses to the brain C. It receives afferent information from the peripheral nervous system D.
