Cocaine blocks the removal of Dopamine from the synaptic cleft, causing the existing Dopamine to bind again and again, overstimulating the cell. At first the cell just fritzes out- producing the high. But then, to counteract the extra stimulus, the body starts to remove Dopamine receptors. That's why it takes an ever increasing amount of cocaine (or meth or whatever stimulant you choose) to produce a similar high.

What are nerve cells specialized to receive and conduct electrical impulses?
Neurons transmit nerve impulses/ electric impulses throughout the body.
How does the myelin sheath and synapse affect nerve impulses speed up or slow down?
Myelin sheath insulates axons for speedier signaling
What nerve processes transport impulses to the cell body?
Axons are the nerve processes that transport impulses to the cell body.
Which nerve fiber do impulses travel slowly?
Impulses travel more slowly through unmyelinated nerve fiber.
What nerve carries impulses to the diaphragm?
phrenic nerve
What are all the systems that nerve agents can affect?
Nerve agents affect the transmission of nerve impulses in your nervous system. Nerve agents can affect the central nervous system, the respiratory system as well as cholinergic nervous system.
Which Mineral is necessary for transmission of nerve impulses in the nerve fibers?
Zinc
What major mineral is required for transmission of nerve impulses?
neuro transmitter is essential for the transmission of nerve impulses in nerve fibres.it is a chemical which is present in the axon terminal bulb(ending of a neuron).
Providing a pathway for the transmission of nerve impulses is the responsibility of the?
peripheral nerve system
What provides for the transmission of nerve impulses way from the cell body?
'Axons'
What cranial nerve Transmits motor impulses that affect heart rate?
Optic nerve
Which two elements are needed to help nerve cells send electrical signals?
It's Sodium and Potassium are necessary for the transmission of nerve impulses
Why is the transmission of nerve impulses often referred to as an electrochemical event?
Myogenic conduction
What is one dietary factor that affects synaptic transmission of nerve impulses?
vitamen b12
What substance aids the transmission of nerve impulses?
Acetylcholine is one of many neurotransmitters. It's the primary NT of voluntary muscular movement. Myelin insulates the axons, allowing nerve impulses to be transmitted faster.
Where does the spinal nerve take nerve impulses?
the spinal nerve sends nerve impulses away from the CNS
Are Nerve impulses electrical signaled?
Nerve impulses are electrical signals.
