Neural Control And Coordination Question 9
Question: The following statements about nerve metabolism excitation and conduction are true except:
Options:
A) Nerve fibre can be excited under anaerobic conditions.
B) Nerve conduction proceeds in the absence of oxygen and development of action potential does not depend on metabolism immediately.
C) In the absence of oxygen, action potential can be generated and nerve conduction proceeds, but later, it fails as the $ N{a^{+}} $ pump cannot operate.
D) At rest, the oxygen consumption in the brain is lesser than what is seen in a nerve.
