Cell signaling and Erectile DysfunctionA review of the current literature.
Primary research vs Review
Case study: Vasodilation •Understand and apply vocabulary in cellular communication. •Understand the importance of proteins and non-protein messengers in cellular communication. •Understand how drugs can be used to treat a condition controlled by a cell signaling pathway. •Understand how a cell signaling pathway can be blocked. •Be able to explain a visual representation of a cell signaling pathway
What is vasodilation?•Widening of blood vessels that results from relaxation of the muscular walls of the vessels.()•Vasodilatorsare agents that widen the blood vessels, cause a decrease in vascular resistance and an increase in blood flow. They bring about relaxation of the smooth muscle in the blood vessel walls or act locally on blood vessel smooth muscle cells.()

Signal TransductionProcess by which an extracellular signal molecule activates a receptor that in turn alters intracellular molecules to create a response.
