It is a normal variation of breathing found in premature and full term infants. It occurs when the infants pauses their breathing for more than 10 seconds at a time followed by a series of rapid, shallow breaths. Then the breathing returns to normal without any stimulation or intervention. These pauses in breathing may be accompanied by minor oxygen desaturation and bradycardia.

It usually occurs when the infant is sleeping deeply, but can occur with light sleep or even when awake. Studies have shown that 78% of healthy full term infants experience episodes of periodic breathing in the first 2 weeks of life, which typically resolves in the first six months of life.

This is not the same as apnea, which is a cessation of breathing for greater than 20 seconds associated with limpness and cyanotic colour change. Periodic breathing are of two types:

1. Cheyne-Stokes breathing.

2. Biot's breathing.

Why oxytocin and vasopressin called as 'neuro hormone'?

Why Oxytocin and Vasopressin called as 'neuro hormone'? -souti das The posterior pitutary secretes two hormone oxytocin and vasopressin(ADH).The hormones are synthesized within the cell bodies of large magnocellular neurons lying in the supraoptic and paraventricular nuclei (PVN) of the hypothalamus. The posterior pituitary hormones are transported in association with specific proteins, called neurophysins , along the axons of the neurons to end in those nerve terminals which lie within the posterior lobe. Prior to secretion, these hormones are stored in secretory granules either in the nerve terminals or in the varicosites called herring bodies . The hormones are secreted in response to nerve impulses originating in the supraoptic and PVN and enter the capill...

TDP Of Insulin

Time Dependent Potentiation of Insulin secretion Glucose causes time dependent potentiation(TDP) of insulin secretion; that is exposure of islets beta cells to high glucose enhances insulin release in response to the stimulus applied later.
