The drug that Jo began using is a stimulant. Stimulants increase neural activity and causes bodily functions to speed up. This drug increases activity in the nervous system by activating specifically the sympathetic nervous system, which arouses the body, also known as the fight-or-flight response.

4a. Neurons communicate using neurotransmitters. First, a neuron has to receive the message through the dendrites, which receive messages. Then, the message passes through the cell body, which is the life support of the cell. Next, the axon receives the message and the neural impulse travels down the axons. The axons are covered by the myelin sheath, which help speed up the neural impulse. Finally, they reach the axon terminal.
4b. Neurotransmitters are the chemical messengers that sends information to a receiving neuron. It is not a hormone because hormones travel through the bloodstream while neurotransmitters travel through the synapse. Also, hormones are messages for organs while neurotransmitters are messages for the
