Answer:
Repolarization
Explanation:
Repolarization refers to the phase during which the resting potential is restored after depolarization. This means that the inside of the axon membrane becomes negative again compared to the outside.
Repolarization is obtained by the functioning of K+ ion channels. The opening of K+ ion channels allows the K+ to move outside of the axon. Movement of positively charged ion (K+) outside of axon makes the inside negative again and the resting potential is restored.
Answer: Option D
Explanation:
The sensory information that is entering from the dorsal ramus of the body is most likely to come from exteroreceptors on the back.
Exteroreceptor are the different afferent nerve endings that has the ability to sense stimuli which originates from the outside of the body such vibration, sound, pain, touch et cetera.
These receptors carry signals from the external back to the dorsal ramus of the spinal cord.
I'm going to assume the correct answer is C.
Probably go to a doctor, preferably the one who talked about the plans of the surgery
