Lecture 15: Respiratory Defense Reflex

Question 1

Pulmonary defensive reflexses

Answer 1

cough, sneeze, diving response, laryngeal chemo reflex, pharyngeal phase of swallow

Question 2

Impairmnet

Answer 2

leads to aspiration, pulmonary infections and increased mortality

Question 3

enhancement or hyperrresponsivness

Answer 3

reduced quality of life, increased morbidity

Question 4

cough and sneexe do?

Answer 4

remove mucous or foreign matter from nasla/pulmonary systems

Question 5

Cough

Answer 5

mechanical manifestation of of neurological problems, receptors in lungs and larynx

Question 6

Diving response

Answer 6

cold water hits face, trigeminal nerve sends info the brain which causes vasoconstriction, bradycardia and apne

Question 7

Laryngeal chemoreflec

Answer 7

causes swallowing, laryneospasm, bradycardia and apnea; problem with intubation

Question 8

airway smooth muscle

Answer 8

narrows airways to limit intrusion of foreign objection more distal airways and stiffen lungs during coughing

Question 9

Bronchospasm/bronchoconstricttion

Answer 9

increased contractile acyivity of airway smooth muscle

Question 10

Bronchodilators

Answer 10

drugs that relax or inhibit contractility of airway smooth muscle

Question 11

Bronchomotor tone

Answer 11

baseline contractile activity of airway smooth muscle

Question 12

Cilia

Answer 12

move mucous from distal airways to larger airways and ultimately out of the respiratory system

Question 13

Mucous

Answer 13

composed of glycoproteins produced by goblet cells and submucousal glands, not much in the airways

Question 14

Functions of mucous

Answer 14

insulator from irritants, antibacterial activity and trap particles

Question 15

Neural control of mucous

Answer 15

parasympathetic regulation of submucousal and goblet cells

Question 16

atropine

Answer 16

decrees mucous secretion and airway constriction

Question 17

proinflammatory release by c-fibers

Answer 17

induce mucous release
