Marijuana and Brain Function

A set of vocabulary flashcards defining key biological and chemical terms related to how marijuana interacts with the human brain based on the provided video transcript.

Neurons

The cells that process information in the brain.

Neurotransmitters

Chemicals released from the axon of one neuron to the dendrite of another to change the electrical charge of the receiving neuron.

Axon

The part of the neuron responsible for releasing neurotransmitters.

Dendrite

The part of the neuron that receives chemical signals from another neuron.

Cannabinoids

Molecules produced in the human brain or found in cannabis that resemble specialized neurotransmitters released by neurons after firing.

Tetrahydrocannabinol (THC)

The specific chemical in cannabis that resembles the natural neurotransmitter called anandamide.

Anandamide

A natural transmitter produced in the human brain that is mimicked by the chemical THC.

Refractory period

A temporary state during which neurons become unresponsive after firing to prevent overreacting or being too dominant.

Dopamine and Norepinephrine

Levels of these neurotransmitters are affected by cannabinoids, leading to experiences of euphoria, relaxation, and pain modulation.

Cannabinoid receptors

Receptors located in brain areas controlling short-term memory, learning, coordination, movement control, and higher cognitive functions.
