Final answer:
Damage to upper motor neurons would be indicated by all of the following except hypotonia.
Step-by-step explanation:
Damage to upper motor neurons would be indicated by all of the following except:
a) Spastic paralysis
b) Hyperreflexia
c) Hypotonia
d) Extensor plantar reflex
The correct answer is c) Hypotonia. Hypotonia is a condition characterized by low muscle tone and reduced resistance to passive movement. In contrast, damage to upper motor neurons typically leads to spastic paralysis, hyperreflexia, and the extensor plantar reflex.
