E. no answer
F. no answer
Question Number 8
afferent neurons are also called sensory neurons... what are NOT a characteristics of them?
A. transmit info from sensory receptors to CNS
B. dendrites are more specialized
C. dendrites collect and transmit information about environmental stimuli
D. they end at a muscle or gland
Question Number 9

Question Number 12
IN resting potential...
A. Na is on the outside and K is in the inside
B. Na is on the inside and K is on the outside
Question Number 13
When the neuron is firing.....
A. Na is on the outside and K is on the inside
B. Na is on the inside and K is on the outside
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!!
Question Number 15
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!!
Question Number 17
What is the space between an axon terminal and a dendrite?
A. calcium
B. nerve impulse
C. synapse
D. action potential
