Adrenergic nervous system
Adrenergic system or Adrenergic nervous system (ANS) is a group of organs and nerves in which adrenaline (epinephrine) and/or noradrenaline (norepinephrine) act as neurotransmitters. ANS is counted as one of the main neurohormonal systems that regulate cardiovascular function, including smooth muscle tone.[1]
Components
The peripheral adrenergic nervous system consists of three main components:[2]
- The sympathetic nervous system (SNS), which comprises the autonomic outflow from the thoracic and high lumbar segments of the spinal cord;
- The parasympathetic nervous system (PNS), which includes the outflow from the cranial nerves and the low lumbar and sacral spinal cord
- The enteric nervous system (ENS), which comprises intrinsic neurons in the wall of the gut.
gollark: My device is still warrantied but not having a laptop for ages while it gets repaired would be very inconvenient, so does anyone know how long this sort of thing generally takes to get fixed (or if there is a simple repair I can do, but I doubt it)?
gollark: I heard a "pop" noise earlier today when using my laptop (Legion 5, 2020, RTX 2060, i5-10300H), and it seems that now heavy GPU load causes a weird periodic buzzing noise (attached; sorry for the poor quality but I had to boost the volume lots for it to be audible, and also the recording is mostly fan noise). I figure it's a GPU power supply issue.
gollark: Discrete = always use dedicated GPU, dynamic = sometimes use integrated GPU, probably.
gollark: It's running but ÆÆÆÆÆ IPv6 configuration.
