Synthesis of neurotransmitters mostly occurs in the neuronal soma.

Answer 19

TRUE, L3 32

Question 20

The ability of a neuron to respond to stimuli by converting it to into a nerve impulse is called Conductivity.

Answer 20

FALSE, this is irritability, L3 22

The sympathetic division of the ANS utilizes both norepinephrine and acetylcholine

Answer 25

TRUE

Question 26

The sympathetic division of the ANS is also called the thoracico-lumber division -

Answer 26

TRUE. Unsure about this one but it looks to be a spelling error Thoracolumbar division is the correct spelling

Answer 30

TRUE, L4 25

Question 31

The neurotransmitter used by the parasympathetic division of the ANS is acetylcholine

Answer 31

TRUE

Question 32

Neurological damage above the brain stem results in flaccid muscles.

Answer 32

FALSE, L4 9, would potentially result in uncontrolled muscle movements instead - spastic

Question 33

Muscle tone is the result of the integrity of muscle fibers’ elasticity

Answer 33

FALSE - L2, S31

Question 34

Sensory pathways to the brain are slower than motor pathways from the brain.
