Anatomy of URT
Neural breathing control centers
1. Cerebral control
  1. Voluntary hypoventilation
  2. Voluntary hyperventilation
2. Central Control
  1. Medulla
    1. Ventral neurons
      1. Expiration
    2. Dorsal neurons
      1. Nucleus Tractus Solitarius
  2. Pons
    1. Lower pons
      1. Apneustic centers
    2. Upper pons
      1. Pneumotaxic
3. Receptors
  1. Chemoreceptors

    2. Peripheral
  2. Mechanoreceptors
    1. Lung stretch receptors
    2. Joint + muscle receptors
  3. Irritant receptors
  4. J receptors
Snoring
1. noisy breathing
2. Mechanism
  1. due to vibration of soft palate and its thin edges due to partial air way obstruction during inspiration

  1. -Alcohol -Sleep apnea -Sleep position -Sleep deprivation
4. TONSILLECTOMY
Excessive snoring with intervals of breath cessation and arousals from sleep.
Signs and Symptoms

Risk factors
1. Excessive weight, Family history, Male gender,
Pathophysiology

2. Neurologic
Investigation
1. Physical examination
  1. Neck circumference, tonsils and tongue, septum and soft palate, blood pressure
2. Mallampati Score
3. Polysomnography
  1. Records brain waves, oxygen levels, heart rate and breathing, as well as eye and leg movements and sleep noises during the study.
Management
1. CPAP
  1. It gently blow pressurized air through your airway at a constant pressure that keeps the throat from collapsing.
2. Lifestyle
Psychological impact
