(a)
The order in which an impulse travels along the reflex arc is
I, II and III
II, I and III
III, II and I
III, I and II
If neuron I were severed
the sensory receptor would detect touch, but the muscle would not contract
the muscle would still be capable of contracting, but the sensory information would not be relayed to the CNS
the reflex arc would not work because sensory information is not received by the CNS
it would be impossible for the information received by the sensory neuron to travel to the brain
Select the correct answer
A
B
C
D
Repolarization occurs in
area B because more K+ ions enter the cell than Na+ leave
area B because more Na+ ions enter the cell than K+ leave
area C because of diffusion of K+ ions out of the axon
area C because of diffusion of Na+ ions out of the axon
The area of the graph that indicates the opening of Na+ ion channels and the diffusion of Na+ ions into the nerve cells is
area A, which represents polarization of the membrane
Area B, which represents depolarization of the membrane
Area C, which represents repolarization of the membrane
Areas B and C, which represent depolarization of the membrane.

Good: grey matter of the brain has myelinated neurons, which have some capacity for repair.
Good: white matter of the brain has unmyelinated neurons, which have some capacity for repair
Poor: grey matter of the brain has unmyelinated neurons, which have little capacity for repair
Poor: white matter of the brain has myelinated neurons, which have little capacity for repair
