Pontine transection leads to
Ans. (d) Decreased muscle tone(Ref: Ganong, 25th ed/p.242)Pontine transection leads to the loss of effects of Pontine reticulospinal tractNormal function of pontine reticulospinal tract - mediate excitatory effects. Excites gamma motor neurons to muscle spindles that maintains toneSo, there is decreased muscle tone
Decerebrate rigidity
Decorticate rigidity
Increased muscle tone
Decreased muscle tone
