Flashcards in Chapter 18 Part 2 Deck (11):
1

Released by all S+ P preganglionic neurons-all p postganglionic neurons -a few s postganglionic neurons -ach has a short lived localized effect

Acetylene (Ach)

2

Released by most s postganglionic neurons -long lasting widespread effects

Norepinephrine

3

Produces ATP during psychical or emotional stress -increases blood glucose for ATP production by breaking down glycogen and fats

Sympathetic functions (fight or flight response)

4

Involves 4 "E" situation emergency exercise,excitement and embarrassment -increase heart rate, force of contraction and blood pressure

Sympathetic functions (fight or flight response )

5

Dilates airways increasing breathing rate -increases sweating and dilates pupils-contracts erector pilli muscles

Sympathetic functions (fight or flight responses )

6

Increases blood flow to essential organs by vasodilating blood vessels to skeletal muscles,heart,liver and fat tissue - decreases blood flow to nonsensical organs by vasostricting blood vessels to gi tract and kidneys decreasing digestion and urination

Sympathetic functions (fight or flight response)

7

Conserves and restores body energy -decreases heart rate,airway diameter and pupil diameter -stores energy by increasing glycogen and fat production

Parasympathetic functions (rest and digest response)

8

SLUDD; salivation,lacrimnation, urination, digestion and defactation

Parasympathetic functions (rest and digest response)

9

1 receptor 2 sensory neuron 3 intergrating center 4 motor neurons 5 effector

Automatic reflexes

10

Is the major control and integration center of automatic nervous system

Hypothalamus

11

Achetoline (ach),noroprinephrine

Ans neurotransmitters
