receptor, major tissues, major functions Flashcards
alpha 1 receptors act on what tissues and have what major function?
act on smooth muscle and sphincters to contract them
alpha 2 receptors act on what tissues and have what major function?
act on nerve endings and they decrease neurotransmitter release
beta 1 receptors act on what tissues and have what major function?
act on cardiac and kidney muscle, they increase HR, and force of contraction, and increase renin release
beta 2 receptors act on what tissues and have what major function?
affect smooth muscle in bronchi, liver, and skeletal muscle. To relax smooth muscle, increase gluconeogenesis, and glycogenolysis
beta 3 receptors act on what tissues and have what major function?
act on adipose, to increase lipolysis
dopamine 1 receptors act on what tissues and have what major function?
act on renal, mesenteric, and cardiac smooth muscle to relax renal vessel smooth muscle
