Morphological and morphometric analysis of human oesophagus mucous membrane layers in the norm in postnatal period show that all membranes have definite stages of development. Among them we can single out: first: from birth to 12 months--stage of secondary differentiation; second: from 12 months to 3 years--stage of combined development; third: 3 to 12 years--stage of intensive development; from 30 to 50 years--stage of before involutive development and sixth: from 50 to old age--stage of involutive development. Each of the stages is characterized by a combination of correlative morphological and morphometric features, which form individual ontogenesis of organ membrane.
