A 58-year-old man presents with difficulty seeing. The man has hypertension and he is largely noncompliant regarding his medications. The examination reveals a rigid hemianopia, and MRI shows a lesion of primary visual cortex. Which relays vital input to this damaged area of cortex? a. Medail geniculate nucleus b. Lateral geniculate nucleus c. Pulvinar nucleus d. Lateral dorsal nucleus

Select the statement that explains the neural mechanism underlying the sensation of fast, sharp pain followed by delayed, longer-lasting pain after an injury.  a. Fast pain is conducted by mechanoreceptors, whereas delayed pain is conducted by fibers with free nerve endings. b. Fast pain is conducted by free nerve endings in the dermis, whereas delayed pain is conducted by deep nerve endings in the subcutaneous layer. c. The receptive fields differ for the two types of pain sensation such that fast pain fibers have smaller receptive fields than the delayed pain fibers. d. Fast and delayed pain represent the progression of the injury; both are conducted by the same fibers. e. Fast, sharp pain is conducted by myelinated axons, whereas delayed, longer-lasting pain is carried by unmyelinated axons.
