Autonomic Nervous System

Slide 2

Homeostasis Integration Feed-back Effectors Receptors

Slide 3

Somatic versus Autonomic NS

Slide 4

Somatic versus Autonomic Nervous frameworks Somatic NS Receptors Integration Effectors 5 detects Cortex (& assoc.) Skeletal muscles Autonomic NS Receptors Integration Effectors Chemo-baro hypothalamus cardiovascular, Osmo-medulla oblongata smooth Receptors muscles organs

Slide 5

Autonomic Nervous framework Two viewpoints - 1 to advance survival - the other to advance in emergency state survival in stable state Sympathetic Parasympathetic Fight or flight Rest and process

Slide 6

Brain territories required in controlling the ANS Figure 11.12

Slide 7

Promote survival in emergency state: - Increase heart rate - Increase breathing rate - Increase circulatory strain - Vasoconstriction of fringe/insignificant veins and - Vasodilation in heart, mind, muscles - Bronchodilation - Iris widening - Increase blood glucose Decrease absorption Decrease digestive juice discharge Decrease digestive tube motility Promote sphincter shutting Opposite of Sympathetic Promotes assimilation Promotes rest Functions: Sympathetic Parasympathetic

Anatomy of the engine ANS Figure 11.1

Slide 10

Motor pathways of the ANS

Slide 11

Sympathetic NS 2 engine neurons Motor neuron 1 in sidelong horn of spinal line between T1 to L3 Motor neuron 2 in the paravertebral ganglia (shaping the thoughtful trunk) Acetylcholine (nicotinic receptor) in ganglionic neurotransmitter, norepinephrine at the organ neural connection Nerve pathways blended with substantial tangible and engine pathways

Slide 12

Motor Sympathetic NS Two exemptions: - Adrenal organ: Motor neuron 2 has developed into a "secretory" neuron which discharges for the most part epinephrine - The security ganglia: ganglia situated between spinal string and effectors - ex: celiac ganglia innervating the digestive framework

Slide 13

Sympathetic trunk: all the connected paravertebral ganglia will respond as a unit to an incitement of the thoughtful NS  heart rate builds, vasodilation of bronchi … . Guarantee ganglia: they won\'t consequently respond as a unit with the engine neurons from the thoughtful trunk

Slide 14

The organ is shaped by the second engine neuron Secretes epinephrine Sympathetic impact maintained The adrenal medulla

Slide 15

Figure 11.5

Slide 16

2 engine neurons Motor neuron 1 in medulla oblongata or sacral spine Motor neuron 2 in a ganglion close to the organ Acetylcholine (nicotinic receptor) in ganglionic neurotransmitter Acetylcholine (muscarinic receptor) in effector neural connection Nerve pathways blended with tangible and engine pathways, aside from Vagus nerve (75% ANS) Parasympathetic NS

Slide 17

Parasympathetic NS (engine pathway)

Slide 18

Neurotransmitters and receptors from the Sympathetic NS

Slide 19

Neurotransmitters and receptors from the parasympathetic NS Figure 11.7b

Slide 20

Receptors in the ANS Cholinergic receptors: Inhibitory or excitatory - Nicotinic: quick - Muscarinic: moderate Adrenergic receptors: moderate, excitatory or inhibitory - α 1 and 2 - β 1 and 2 (and 3)

Slide 21

α 1 and 2: partiality NE > E for the most part excitatory β 1 and 3 fondness NE = E excitatory β 2 liking E > NE inhibitory Adrenergic receptors Figure 11.8a

Figure 11.7

Slide 25

Drugs following up on the cholinergic receptors: - agonist: recreate parasympathetic impact - enemy: squares parasympathetic impact (impersonates thoughtful agonist) Drugs following up on the thoughtful NS - agonist: reproduce thoughtful impact - rival: pieces thoughtful impact (emulates parasympathetic agonist) Effects of different medications on the ANS

Slide 26

Epinephrine and ephedrine are given in vaporized in individuals experiencing an asthma assault. - Knowing that these medications are adrenergic agonists, which impact do you expect on the bronchi? - Which reactions would you say you are prone to see? Allude to Table 11-2 from the book to answer these inquiry

Slide 27

Propanolol is a beta-blocker. - What is this medication impact on the heart? - Which reactions would you say you are prone to see? Allude to Table 11-2 from the book to answer these inquiry

Slide 28

Atropine is a muscarinic cholinergic adversary. - What is this medication impact on the students? - What is this medication impact on the heart? - Which reactions would you say you are liable to see? - Will skeletal muscles be influenced by this medication? Allude to Table 11-2 from the book to answer these inquiry
