Answer to Question 1

B
Explanation: A ventricle is a cavity within the brain tissue that contains cerebrospinal fluid. Gyri are the convolutions on the surface of the brain. A synapse is the point at which the axon of one neuron meets the dendrite of the next neuron. The sulci are the valleys separating the gyri.

Answer to Question 2

A
Explanation: Urethr/o means urethra and -algia means pain; thus, urethralgia means pain in the urethra. -itis means inflammation, so urethritis means inflammation in the urethra. Ureter/o means ureter and -ectasis means dilation, so ureterectasis means ureter dilation. -algia means pain, so ureteralgia means ureter pain.
