Question 41

first step of a reflex arc, the blank is stimulated by a detectable environmental blank

Answer 41

receptor, stimulus

Question 42

second step of reflex arc, the blank stimulates a blank neuron that sends a signal to the blank for processing

Answer 42

Receptor, sensory, CNS

Question 43

in step three of the reflex arc, the blank from sensory neuron to another neuron

Answer 43

transmission

Question 44

in the fourth and fifth steps of a reflex arc, a blank is stimulated and sends a signal to a blank

Answer 44

motor neuron, effector

Question 45

Answer 45

stretch reflex

Question 46
