Question

_____ act on the nervous system to increase its overall activity and general responsiveness.

Answer 1

STIMULANTS act on the nervous system to increase its overall activity and general responsiveness.

Step-by-step explanation:

A networked, organized group of cells known as the nervous system is responsible for carrying electrochemical inputs from sensory receptors to where a response occurs.

Stimulants are a subclass of psychoactive drugs that stimulate brain activity. These substances can transiently improve mood, consciousness, and alertness. Many people use legal stimulant medications.

Many stimulants have addictive potential. Although stimulants have many things in common, they all have different qualities and ways of working. Drugs that are classified as stimulants include caffeine,cocaine, etc.

Answer 2

Step-by-step explanation:

One of the main factors that can increase the overall activity and responsiveness of the nervous system is the release of neurotransmitters such as adrenaline and noradrenaline. These neurotransmitters are released in response to stress or excitement and can increase heart rate, blood pressure, and alertness.

Other factors that can increase the activity of the nervous system include exercise, caffeine, and certain drugs such as amphetamines and cocaine. These substances can stimulate the release of neurotransmitters and increase the activity of neurons in the brain.
