Question
It doesn’t involve the kidneys, but neurons called ORNs (“O-R-Ns”) relay information about this sense to mitral and tufted cells at ball-like structures called glomeruli. For 10 points each:
[10e] Name this sense responsible for detecting and perceiving pheromone and odor molecules.
ANSWER: smell [or olfaction; accept olfactory receptor neurons; accept olfactory bulbs]
[10m] Since mitral and tufted cells do not innervate this brain structure, olfaction is the only sense it does not relay to the cerebral cortex. This upper portion of the diencephalon (“dai-en-SEH-fuh-lawn”) is also involved in regulating consciousness.
ANSWER: thalamus [reject “hypothalamus”]
[10h] Olfactory signals between ORNs are mostly transduced by these proteins, which contributes to neural depolarization after getting activated by a cascade involving Golf (“G-olf”) and ACIII (“A-C-3”). The activity of these ion channels is controlled by the binding of cAMP (“camp”) or cGMP (“C-G-M-P”).
ANSWER: cyclic nucleotide-gated ion channels [or CNG channels]
