Exhorts; impulses (5)
I believe the answer is:
urges
I believe this is a double definition.
'exhorts' is the first definition.
('urge' can be a synonym of 'exhort')
'impulses' is the second definition.
('urge' can be a synonym of 'impulse')
(Other definitions for urges that I've seen before include "Exhorts or prods" , "Compulsions" , "Presses to do something" , "Advocates strongly" , "Drives" .)
