Question Number 14

What are the differences and similarities between sensory motor and relay neurons? (this would be an essay question so im just going to write the answer in the possible answer blanks... just pick F to get it right)

A. Sensory neurons transmit messages from sensory organs to CNS, also called afferent, their cell bodies are usually in a different location than other neurons because of their specialized dendrites

B. motor neurons transmit messages to muscles and glands from CNS, very specialized axon branches

C. relay or interneurons are almost only located in the CNS they are specialized at both dendrites and axon but not as specialized as motor or sensory neurons, they help differentiate between messages and amplifies messages

F. this is the answer... but read the answers A B and C carefully and study for test!!

IN resting potential...

A. positively charged on the outside and negative on the inside

B. negatively charged on the inside and positively on the inside

Question Number 16

Another essay question... What happens when the neuron is stimulated? (answer is F)

A. when the neuron is stimulated, the distribution changes for a milasecond

B. in this millisecond, the inside is positive and the outside is negative

C. This is caused by Na= coming in

D. this is called depolarization

E. after it is stimulated, re polarization causes it to go back to resting position

F. this is the answer... but read the answers A B C D and E carefully and study for test!!
