Drugs

Question 1

Whats the neurotransmitter ans receptor in somatic N.S?

Answer 1

ACh and nicotine receptors

Question 2

What’s the neurotransmitter in autonomic N.S?

Answer 2

Ach –》nicotine》ach –》 muscarine

Question 3

What is the neurotransmitter in parasympathetic N.S?

Answer 3

Ach》 nicotin》 ach》muscarine

Question 4

What’s the neurotransmitter in sympathic N.S?

Answer 4

Ach》 nicotin》Nad 》alfa/beta

Question 5

What’s the function of anticholinergic drugs?

Answer 5

Blocking the neurotransmitter ACh

Question 6

What’s the anticholinergic drugs?

Answer 6

Antimuscarinic and antinicotinic

Question 7

What’s the function of sympathic N.S?

Answer 7

Fight and flight

Question 8

What’s the function of parasympathetic N.S?

Answer 8

Rest and digest

Question 9

What’s the characteristics of the preganglion in parasympathetic N.S?

Answer 9

Lightly myelinated

Transmitters ACh

Question 10

What’s the characteristics of a preganlionoc axon in the somatic N.S?

Answer 10

Meylated, ACh 》 skeletal muscle

Question 11

What’s the characteristics of a postganlionic axon in parasympathetic N.S?

Answer 11

Unmeylated. Ach

Question 12

What’s the characteristic of a sympathic postganglion?

Answer 12

Unmyelinated

Question 13

What’s a anticholinergic drug?

Answer 13

It blocks the neurotransmitter ACh in the central and peripheral N.S
Two types receptors affected:
Nicotinic and muscarinic
MAJORY OF ANTICHOLINERGIC DRUGS ARE ANTIMUSCARINIC

Question 14

Witch is the cholinergic receptors?

Answer 14

Nicotinic and muscarinic

Question 15

What’s the function of anticholinergic drugs?

Answer 15

Blocking the action of ACh in central and peripheral N.S, this inhibits nerveinpulses responsible for involuntary muscle movements and various body functions

Question 16

What is a antimuscarinic agent?

Answer 16

Operate on the muscarinic receptor = mAChR BLOCKERS (majority of all anticholinergic drugs are antimuscarinic)

Question 17

What is parasympatholytic agent?

Answer 17

An anticholinergic agent that INHIBITS the transmission of ACh mediated stimulation by competitive occupancy (antagonist) of cholinergic receptors of postganlionic parasympathetic nerves. MUSCARINIC RECEPTORS is modified and smooth muscle and secretorycells effected

Question 18

what is the function of anticholinergic drug?

Answer 18

it blocks the neurotransmitter ACH in the central and peripheral nervous system by blockiing the cholinergic receptors of postganlionic of parasympathetic (muscarinic)

Question 19

what is the function of antimuscarinic agents?

Answer 19

the modify the muscarinic effects of ACH on smoot muscle and sensorycells but NOT the nicotinic effects on ganlionic transmission points and endplates of the skeletal muscles.

in heart block cardioinhibitor effect on muscarinic receptor in the sinus node by ACH release from the vagalnerve (parasymptatetick nerve)

Question 20

what is atropine?

Answer 20

anticholinergic agent that blocks ach in central an peripheral N.S

Question 21

what is anticholinesterase?

Answer 21

an agent thats inhinbits the acetylcholinesterase ensyme —> no hydrolysis of ACH—> increasing borh level and duration of action of the neurotransmiiter ACG —> muscular spasm –> spatic paralysis
