The addictive substance is called Nicotine.
Answer:
a.Hypotonic
Explanation:
Lower motor neurons refer to the spinal and cranial motor neurons that directly innervate skeletal muscles.
When injury occurs to lower parts of the motor system , such as motor systems or their axons , deficits may be well localized. If the motor nerve to a muscle is damaged , that muscle develop paresis or complete paralysis. If their motor nerves are transected ,muscles become flaccid (atonia ) and eventually develops atrophy.
Damage to these neurons is associated with :
1) Flaccid paralysis
2) Muscle atrophy
3) Fasciculations
4) Hypotonia
5) Hyporeflexia.
Hence option A is the right answer.
