Catecholamines (Norepinephrine, Epinephrine)

Dr. Morton explains catecholamines, their synthesis, storage, release, receptor binding, and degradation. Catecholamines like dopamine, norepinephrine, and epinephrine are synthesized in a specific order, stored in vesicles, and released into synapses. The video also covers adrenergic receptors and the removal of catecholamines through reuptake, diffusion, and degradation.

How does the adrenal medulla contribute to the secretion of catecholamines?

What is the significance of the chromaffin cells in the adrenal medulla?

Discuss the differences between norepinephrine and epinephrine.

What mechanisms are involved in the removal of catecholamines from the synaptic cleft?
