    we have one heart and two lungs, i.e. Beta 1 in heart, beta 2 in lungs.
    sympathetic system stimulates the heart and inhibits elsewhere. Heart has beta 1 receptors in greater quantity.
    blood vessels have alpha 1 receptors to perform vasoconstriction, and beta 2 for vasodilation.

    Current trying to figure out why taking propanolol that was prescribed to me for performance anxiety made it so much worse about an hour and a half after taking it, this made it easier to understand the receptors it was acting on

      Quick question
      Does Beta 2 stimulate Insulin secretion ? And if it does , why ? Becuase parasympathetic as I am concerned is responsible for secretion of insluin .

    • @lyndsy5302
      @lyndsy5302 2 года назад

      @@MohammedHassan-dj8wy I'm late, but answering you helps me recall what I have learned. PSNS is responsible for secreting insulin during normal processes, but beta-2 receptors, which are part of your SNS (remember fight or flight) also release insulin in times of stress. From what I learned, glucose is released from muscle cells, so insulin is released to get glucose into the tissues that need to function well in times of stress.

    You have the etymology of sympathetic wrong @ 5:35. It's not used as in "having sympathy for someone" it's used as in "multiple actions in sympathy". All those things, faster heart rate + constrictions + gut slows are happening in sympathy. Therefore, sympathetic nervous system. (also, what does having sympathy for someone have to do with fast heart rate? lol)
    Love this video though, just learning about this a little for fun. Too fast for me, but I just slow it down and it's very interesting even for someone without detailed medical knowledge.

      It’s the Parasympathetic that secretes saliva for digestion.
      Sympathetic may only secrete some thick visid secretion to make you thirsty, so that you can drink water.
