Physiology Exam 2

1. Parasympathetic

   • Preganglionic
     • Postganglionic
       • Cholinergic
         • AcH
           • Synapse muscarinic (M1-M5)
       • Very short
     • Cholinergic
       • AcH
         • Synap with nitoctinic
     • Much longer
   • Rest Digest

2. Sympathetic

   • Preganglionic
     • Postganglionic
       • Andronergic
         • Nor and epi
           • Two exceptions
             • Arrector pili muscle and sweat glands
               • where and pre and post symp are AcH
       • Much longer
     • AcH
       • Cholinergic
         • Synapse with Nitoctinic (N1 N2)
     • Short
   • Fight or Flight
   • Innvates all blood vessel

3. AP favors high Ca outside

   • EPSP excitatory
     • IPSP inhibit
       • De or Hyper polarization
     • Only depolarization
   • Electrical Fast di direction direct comm
     • Chemical Not direct comm, unidirection seperate synaptic cleft
       • Exo involve SNARE v and t
   • Endo of Kiss and run
     • Kiss not whole collapse of vessicile into membrane.

4. Ionotrophic

   • Metatrophic
     • Secondary messengers
   • gate (open of closed)

5. Adaption

   • Pacinian Corp
     • Fast
   • Temp does adapt
   • Pain Receptors
     • DONT adapt
     • Muscle Pain
       • Spindle
         • DONT ADAPT
           • Tonic receptors
           • Gamma Bias
             • altered set point-Not adaptation

6. Gamma Motor

   • Muscle tone
   • Alpha motor
     • Stimulate skeletal muscles

7. Reverbrating

   • Postive Feedback

8. Adernergic Receptors

   • Epinephrine: Beta
     • Low epi: vasoconstriction, Greater cardiac stim, bronchodila
     • Increase Bronchdil, vasodilation, cardiac stim
   • Norepinephrine: Alpha
     • Low nor: reflex bradycardia, and extensive vasoconst
       • Increase vasocontri, and some cardiac stimul
   • Dopamine:Beta equally or only alpha 1
     • Increase: vasodilation, cardiac stimul
       • Decrease: vasconst only
   • B1: heat; B2: vascular and lungs
   • Anticipatory response: FEED Forward Mech

9. Adernal Gland

   • Release mainly Epi, lil nor

10. Sym: Mass discharge

    • Except: thermo skin
    • Increase BP, flow
      • Decrease Blood coagul
      • Release glucose liver to muscles
      • increase cellular meta
        • Increase muscle strength and activity

11. Para: Discrete Discharge

    • Except: salivate ad food stomach prepares
    • Vagus outflow only alters rate
    • Stimulation along GI

12. Baroreflex Receptors

    • In Carotid and aortic arch
    • Maintain BP homeostatis
      • Via negative feed back loop
        • Goes to nucelus. Tractis, Sole
    • Stops us from passing out on standing
      • Arotic arch usually under press
        • If increases via running
          • Send signal Help stretch Vagus send to NTS
            • Tells heart to slow down
            • Aorta stretch more, signals firing more

13. Vaso Vagal

    • Sympathetic withdraw
      • Oppress vagus
      • Heart Rate slows down
      • Pass out
    • public speaking

14. Autonomic Reflex

    • Feed Foward
    • No just cardio but GI too
    • think of food
      • Salivate: Parasym outflow
