Question 4

Accepted Answer

A) The dog is able to sit and roll over in response to commands. 
B) The dog can move proximal effectors normally,but not distal effectors. 
C) The dog demonstrates reflexive withdrawal of its foot in response to sudden stimulation. 
D) Only vital motor functions such as breathing and heartbeat are intact in this animal.

C) The dog demonstrates reflexive withdrawal of its foot in response to sudden stimulation. 
D) Only vital motor functions such as breathing and heartbeat are intact in this animal.

Question 5

In studies of the role of sensory feedback on motor behavior in monkeys,Taub and Berman (1968)first severed the dorsal roots for one arm and observed motor behavior (Phase 1),and then severed the dorsal roots for the remaining intact arm and again observed motor behavior (Phase 2).They found that the monkeys

Accepted Answer

A) could move and use their arms only when the corresponding dorsal roots were intact. 
B) preferred to use their intact arms following Phase 1 but returned to using both arms following Phase 2. 
C) preferred to use their disconnected arms following Phase 1 but returned to using both arms following Phase 2. 
D) required sensory feedback to use and move their limbs.
