This sensation involves a simple system with receptors that are neuron dendrites. The only known example of neurons with a high rate of replacement in the adult human are the. D) olfactory receptors. Chemicals.
D) Human power of olfaction is as powerful as that of most other mammals. E) Olfactory stimuli do not pass through the thalamus before journeying to the olfactory cortex. Answer: D Diff: 1 Learning Outcome: Skill Level: 1 Reviewing Facts and Terms 19) An example of neuronal replacement in the adult human involves the A) gustatory receptors.
undergoes considerable turnover,the division and differentiation of basal (stem) cells in the epithelium produce new receptor cells. --This turnover is one of the few examples of neuronal replacement in adult humans. --The total number of receptors declines with age, and those that remain become less sensitive.
It is clear, though, that an understanding of the role of neuronal replacement in adult brain must take into account the fact that the great majority of new neurons are transient and will, in due course, be replaced.
