What is a Neuron?

A neuron is a nerve cell that is the basic
building block of the nervous system. Neurons
are similar to other cells in the human body in a
number of ways, but there is one key difference
between neurons and other cells. Neurons are
specialized to transmit information throughout
the body.

How Does Marijuana Affect the Nervous
System?

THC acts on cannabinoid
receptors which are found on
neurons in many places in
the brain. These brain areas
are involved in memory (the
hippocampus), concentration
(cerebral cortex), perception
(sensory portions of the
cerebral cortex) and
movement (the cerebellum,
substantia nigra, globus
pallidus). When THC
activates cannabinoid
receptors, it interferes with
the normal functioning of
these brain areas.
What Neurotransmitters are Affected by
Marijuana?
