Start studying Nervous System: Sensory. Learn vocabulary, terms, and more with flashcards, games, and other study tools. 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. 32. 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: 9.3 Skill Level: 1 Reviewing Facts and Terms 19) An example of neuronal replacement in the adult human involves the A) gustatory receptors.
Start studying Physiology Exam 2. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Search. The only known example of neurons with a high rate of replacement in the adult human are the _____ Olfactory receptors. We infer that mechanisms of neuronal replacement in adult brain have not evolved as a generalized mechanism for repair, as occur for example in skin, muscle, bone, and liver. Instead, it is a capacity vested only in particular subsets of brain cells.Cited by: 300.
Feb 01, 2002 · Neurogenesis affects a minority of cell types in adult brain. Within the forebrain new neurons are added only to some, narrowly defined circuit positions. For example, the song system of oscine songbirds (Fig. 1) consists of a descending motor pathway necessary for the production of learned song (Nottebohm et al., Cited by: 222. Postnatal or adult neurogenesis and neuronal replacement may also play a role in therapies aimed at restoring impaired brain function. An understanding of various aspects of spontaneous neuronal replacement may also be used to increase the success of procedures that use grafted material. An example of this approach was already mentioned above.Cited by: 229.
