RESPIRATORY REFLEXES

RESPIRATORY REFLEXES

Respiratory rhythm is altered reflexly.

Occurs in response to metabolic signals & other stimuli.

MAJOR RESPIRATORY REFLEXES:

Hering-Breuer inflation reflex.

Hering-Breuer deflation reflex.

Irritant receptors.

J-reflex/J-receptors.

Head’s paradoxical reflex.

Afferent from proprioceptors.

1. HERING-BREUER INFLATION REFLEX:

Mediated by pulmonary stretch receptor.

Mechanism:

Lung inflation above particular volume results in,

Reflex inhibition of inspiration.

Initiation of expiration.

Major actions:

Limits tidal volume.

Increases respiratory frequency.

Prevents lung hyperinflation.

2. HERING-BREUER DEFLATION REFLEX:

Rapid lung deflation initiates prolonged inspiration (reflex hyperpnea).

3. IRRITANT RECEPTORS:

Respiratory tract mucosa contains rapidly adapting “Irritant receptors”.

– Responds to noxious gases, cigarette smoke, inhaled dust, cold air, etc.

Information from irritant receptors conveyed to CNS by vagal afferent fibers.

– Nerve stimulation causes reflex bronchoconstriction, cough & increased mucus secretion.

4. “J-REFLEX”/”J-RECEPTORS”:

J- receptors –

– Sensory nerve endings of non-myelinated (type – C) afferent fibers in vagus nerve.

“J” refers to “Juxtacapillary”.

– Juxta-position to pulmonary capillaries,

– In alveolar interstitium.

Stimulating factors:

Increased in alveolar interstitial fluid → Interstitial edema.

Alveolar capillaries engorged

– As in CHF/pulmonary microemboli.

Stimulation reflexly causes,

– Severe tachypnea

– Bronchoconstriction

– Hypotension.

– Bradycardia.

Major stimulating factor:

Increased pulmonary capillary pressure.

– Eg: Especially during exercise at high altitude.

Effect of stimulation:

Produces tachypnea → Leading to dyspnea.

Inhibits stretch reflex in skeletal muscles → Inhibits exercise.

Protecting from pulmonary edema precipitation.

5. HEAD’S PARADOXICAL REFLEX:

Lung inflation further induces inflation.

Functions:

Physiological role of Head’s reflex is uncertain.

Play a role in initiating respiration at birth.

– Fetus is delivered with empty lungs.

– First breath doesn’t fill lungs completely.

– Each inflation promotes further inflation, facilitating lung filling.

6. AFFERENT FROM PROPRIOCEPTORS:

Proprioceptive afferent impulses from muscles & joints → Stimulate inspiratory neurons,

– Hence, increase pulmonary ventilation during exercise.
