Explanation:

• Question 31: Cranial nerves originate from the brain and brain stem. The spinal cord gives rise to spinal nerves. The cauda equina is a collection of spinal nerve roots. The pia mater is a meningeal layer.
• Question 32: In medical terminology, "kerat" refers to the cornea and "-itis" means inflammation. So Kerat/itis is inflammation of the cornea.
• Question 33: Pleurisy is inflammation of the pleura. The pleura has two layers - the visceral (covers the lungs) and parietal (lines the thoracic cavity). Inflammation between these two layers is pleurisy.

Answer:

• Question 31: brain and brain stem
• Question 32: inflammation of the eye’s cornea
• Question 33: visceral/parietal
