<p>Axoplasmic transport is the movement of neurotransmitters or drugs along the axon of a neuron. It plays a crucial role in the distribution of drugs within the brain by allowing substances to travel from the cell body to the axon terminals.</p> Signup and view all the answers

<p>Endogenous opioids are naturally occurring peptides that act as neurotransmitters. They play a crucial role in pain modulation and reward pathways, influencing the effects of opioid drugs.</p> Signup and view all the answers

<p>Opiate receptors are specific protein molecules in the brain that bind to endogenous opioids and opioid drugs. Drugs like heroin exert their effects by binding to these receptors, leading to analgesia, euphoria, and other central nervous system effects.</p> Signup and view all the answers

<p>Synthetic opiates are artificially produced drugs that often have higher potencies than naturally occurring opiates. They have revolutionized pain management but also come with a higher risk of abuse and overdose.</p> Signup and view all the answers

<p>THC acts on cannabinoid receptors in the brain, altering neurotransmitter release and affecting various brain functions. This interaction leads to the physiological and psychological effects associated with marijuana use.</p> Signup and view all the answers

<p>Sensitization is a phenomenon where a drug becomes more effective with repeated use, leading to an increased response. This contrasts with tolerance, where the body adapts to a drug, requiring higher doses to achieve the same effect.</p> Signup and view all the answers
